Proton Polymer Battery

To top it off, they can make it in a credit card-thin format. Very cool, and about time!"
and/or put smaller cells in parallel and series to achieve the desired voltage/internal resistance
Like a beowulf cluster of batteries?
Sorry, couldn't resist.
One of the most interesting aspects is extremely fast (5 minutes!) recharge times. i.e. the battery might not last as long, but you'd be able to fully recharge it while waiting in line to board the plane (much less while waiting for the plane to arrive). 10K cycles means that you could fully discharge and recharge it 3 times a day and it would still have a 10 year life cycle (In my world, I think this would mean ~5 years ( at 3 discharges/day) before you started to notice serious capacity dropoff.
For example, you could fast-charge it (full charge) while in transit between customers and not have to worry about battery death. 30 seconds plugged into a wall circuit might give you an extra 2 hours of stand-by power
THE DOWNSIDE -- SAFETY
Fuse early, fuse often.   I've seen a small (VHS casette sized) battery vaporize a 30A fuse without breathing hard. Something that can give you 10 times the discharge of a lead acid battery could couple as an emergency ark welding power supply. As long as you didn't drain it, A furby-sized battery could jump start a car (but you'd still need 2-gauge jumper cables to connect it!). If you shorted it out with 12Gauge (extension cord) wire, you could probably burn off the insulation in under 10 seconds. Now think what would happen to your thigh if you stuck one of these batteries in your pocket and shorted it out on your keys -- We're talking instant branding here (not to mention the hole burnt in your pants).
ON THE BRIGHT SIDE - QUAKE LIVES
I think that, with a fuel-cell generator pack, you could probably use one of these things in a man-portable rail gun. The scarey thing is that it would probably work much like the quake-3 unit (fire off a round (or three), and then wait for the power pack to reload).

After reading the various replies in this thread, I couldn't resist...
By looking at the page of NEC it seems to suggest that their 'cell' is 12V/20mAh, with a connected version of 10 cells for 12V 200mAh. The 200mAh model is about as thick as three or four floppy disks and about 2/3 the height.
The average laptop-battery is about 1 1/2 the height(length) of a floppy and about 5 floppies think. (well, mine is). My current battery provides me with about 3.5 hours of juice and it provides 3600mAh at 10.8V. (Lithium/Ion)
Now there's always the difficulty in expressing these things because almost all variables are related. I'll try to calculate the batteries back to their energy-values in Joules.
3600mAh at 10.8V provides (3.6A * 10.8V * 3600 seconds)== 139968 Joules of power.
For the sake of argument, let's compensate the 'thinness' of the battery (compared with my current battery) by assuming three fit in the length of the 'current' battery.
That would provide 600mAh at 12V in a similar battery. This mounts to (0.6A * 12V * 3600s) 25920 Joules. Even in a very positive estimate of 5 200mAh cells in the same size, it would provide only (1A * 12V * 3600s) 43200 Joules of power. (this last figure is slightly under 1/3 of the amount of power my current battery provides)
As a conclusion, the new battery from NEC won't give us the "durability" most of you have been celebrating about. However, as NEC's article states, it has a significantly higher discharge rate. This 'battery' therefore sooner approaches (as some posters already stated) the specifications of 'burst' capacitors.
Then again, it has the potential for improvement. As Ericsson is already working with Lithium/Polymer (i.e. Electron/Polymer, as opposed to NEC's Proton/Polymer) batteries in their cell-phones, we should be seeing credit-card thickness batteries with longer lifespans for (to begin with) PDA's/cellphones pretty soon.
Another thing I noticed in the posts is a discussion about the units of measurement. Things like the 'Coulomb' and the 'KWh'.
Basically, energy is expressed by Joules. And Power is expressed in Watts, which equals 1 Joule 'consumed' in 1 second. Electrical power (consumption) is calculated by the formula of Power(consumption) equals Voltage times Current (or P=V*I).
[Start inflammatory bit]
Up until now, this has all been highschool-level physics. Which means either one of three things:
1) The posters didn't read the article, clicked on reply and started yapping away,
2) The posters haven't finished highschool yet.
3) The posters won't finish highschool.
[End inflammatory bit]
So the timespan, potential and current are interconnected. Enter the Coulomb. Coulomb is a measurement of charge. Current can therefore be expressed in Coulombs as well as Amps.
1 Coulomb/sec equals 1 Ampere. 1 Ampere equals 1 Watt over 1 Volt. Which in turn means 1 Joule over 1 Volt in 1 second.
(1sec * 1J) * 1V == Watts * Potential == Current
1sec * (1J * 1V) == Time * Coulombs == Current
[Thus Coulomb is the relation between energetic value and potential difference]
The KWh is merely a 'compound' unit for use by power-companies who don't want to daunt their customers by stating a 9-figure number on the bill as the 'power consumed'. Besides, the cost/Watt consumed are so small, they can't reasonably calculate with it.
So, the KWh is one KW (1000 Watts), sustained for one hour (3600 seconds), which results in 3.6 million watts. Stating "200KWh consumed" looks so much friendlier than saying "720000000 Watts consumed" (720 _million_ watts).
Running 4 computers 24/7 in your home (which I do), without the monitors and having saved on the number of harddisks, would probably end up around 300Watts continously. 300 Watts * 3600 * 24 equals 25920000 Watts per day, or 7.2 KWh.
This, at 365 days a year, ends up in a whopping 2628 KWh on computer power-consumption a year alone.
Didn't that catch phrase come from Mr. Rogers?
What do you mean "can we say"? What does this phrase mean?
--
Escher was the first MC and Giger invented the HR department.
It's credit card thin, right? What about stacking 10 of them in the section where the battery slot is and modding the power down to something reasonable? Kind of like when you plug a 9-volt adapter into the wall to power a small piece of electronics, like a phone.
- I don't care if they globalize against free speech. All my best free thoughts are done in my head.
Compare this to something as creaky and ancient as a Cessna 152 carrying 25 gallons of gasoline and a 25% efficient engine. Gasoline yields about 119,000 BTU/gallon, or 30000 BTU/gallon at the crankshaft. That 25 gallons of gas would yield 750,000 BTU or 220 KWH of work; divided by the aircraft's 1670 pound gross weight, that's 132 watt-hours per pound.
Even the NEC battery is about a factor of 20 behind what you need to power a real heavier-than-air personal transport. Airplanes will not be electric any time soon.

Time is Nature's way of keeping everything from happening at once... the bitch.
Battery guys use the following terms:
Power/Volume = power density
Energy/Volume = energy density
Power/Weight = specific power
Energy/Volume = specific energy
Interesting bit o' trivia: the theoretical limit for a battery's specific energy is c^2. Disscuss amongst yourselves.
Here is a more recent article (August 2000), so it appears to be truthful. It includes more correct info pertaining to power vs. energy density as well.
OK, you say electric cars, but for aircraft the advantages that apply to cars would be even more attractive.
I've done a little electric aircraft RC modelling. They were almost as good as the "slimers" (various kinds of petrochemical fuels) but never quite, because the weight of the batteries always kept them from achieving the same power to weight ratios of otherly powered craft. Also they tend to have a run time of less than ten minutes, with performance rapidly dropping off towards the end. Until recently they were limited just to NiCd batteries, because of the high current draw required - LiIon and NiMH just couldn't dump the 80A that some of the big brushless motors like. Lightweight, high capacity batteries will make internal combustion models a thing of the past.
Extend that idea to passenger aircraft... For a start, it would make them much less flammable (remember KLM in 1973?), and if people were farsighted enough to get a solar infrastructure built for recharging, much, much cheaper.
Even possibly affordable enough for personal ownership. And of course very quiet, and almost pollution-free - not the sort of thing a neighbour would complain about at all.
The battery itself uses sulfuric acid solution
somelines further:
Free of pollutants
Sounds contradictory to me...
After an exhaustive "9 volt to the tongue" type experiment outside NEC's cafeteria, 98% of the random subjects all reported that the "damn proton battery hurts like a motherfucker." The remaining 2% had tongue piercings and could not legally participate in the in-company experiment.
Results will be expected on-line shortly at the NEC homepage, with Realmedia clips of the after-effects of licking including slurred incomprehensible speech that may or may not be profanity.
An NEC engineer was later quoted as saying, "we're working hard on clear and concise warning labels for kids so they don't do the same thing, but it probably won't make much of a difference," probably refering to socially inept and possibly really stupid children like his own son, Samuel, who is often the subject of taunts and dares.
The press release compared the energy density of the new batteries to that of lead-acid cells. It wasn't clear whether they were referring to the energy density by volume or by mass. (My guess is by mass, which is more favorable to them because lead is so effing dense).
Lead-acid isn't all that great for mass density, so don't expect greatly increased range from electric vehicles. The main advantages are that (A) the plastic can probably (eventually) be made cheaper than the lead, and (B) it can be charged quickly (provided that mega-amp charging cables for cars become common, which is another story...)
I wonder if people have considered the safety issues of batteries with high energy densities and high discharge currents. Under the right conditions, some batteries can explode, catch on fire, ...
:-)
Yeah, people are really worried about such things, which is why gasoline-powered cars never caught on.
"The question of whether machines can think is no more interesting than [] whether submarines can swim" - Dijkstra
or 72mA in 1/8th of a hour, etc, etc. - that is, sure you can light an LED to half brightness for an hour, or the same battery can blaze a floodlight for a few seconds, it's the same amount of enerfy, just released slowly or quickly. Heck, I have plans for a 100,000w laser that runs off a 6v flashlight battery, only thing is the pulses are only 10nS long. One Ampere is one coulumb/second - the units get quite comfortable once you work with them and actually build things for a few years, constipated liberal arts majors notwithstanding. Only newbies have to expand a unit of measurement into it's basic physical quantities. After saying "coulombs per second" five hundred thousand times, we find it much faster to just say "amps". "Jake, could you flip off that 20 coulombs per second circuit breaker? Thanks!" Got any 1 millionths of a coulomb-volt capacitors anybody?
But I still wouldn't accept a ride in his new car.

My dad works in the Battery business, and as off 2002, this new battery will appear in cars. It should be appearing soon in Harleys and Lawn tractors. INFO on INSPIRA http://www.johnsoncontrols.com/bg/NewTechnologies/ tech_info/tech_info_main.htm
Problem with batteries is that there is a tradeoff between discharge rate, and reserve power. Discharge rate is important for starting engines, but reserve is important for say, running you radio. So you got a battery that's okay with both.
Enter "Inspira", the Thin Metal Foil Lead Acid battery. These lil buggers are POWERFUL. A 6 cell unit not much bigger than a latern battery can crank out 1200 amps for 30 secs. It recharges in 15 minutes too. Now starting a car of course takes a lot less than 30 secs... ;)
The thing can crank a DIESEL SEMI as fast as a car. The glow plugs warm up instantly basically, because of the high current.
They're sealed lead-acid, no more need to add water, and they're recycleable using the current means for recycling car batteries.
Using a seperate Deep Cycle marine battery for reserve, and this battery for cranking, the combined weight is less than a normal car battery. You can keep a spare cranking battery in the trunk, top it off on a home charger that plugs intoa wall outlet. Keep a spare, if the first cranking battery goes dead, pop it out, and plug the spare in! The circuitry used in the battery docking hardware for power management, well, they're adding car security too it too. You'll get a keychain dongle, and with a press of the button, it will disconnect the battery circuit from the car.
Best of all, it's backwards compatible with current cars! You'll be able to go to a store, and BUY a drop in replacement that fits in the current battery tray. Drop it in, plug in the batteries, and off you go! And because that lil battery is so powerful, no more problems starting on cold days.
We had a test model in our van for a year.
NB, a electric drag racer equipped with Inspiras instead of normal lead acid car batteries, last year did so well, it can no longer compete in the electric class! It will now be racing with conventional fueled dragsters! By switching to inspira, they managed to shave 500 lbs off the weight. Drag races last a lot less than 30seconds, this makes them perfect for large banks of these lil batteries.
What NEC is promising, Johnson Controls delivers today... ;)
(Now's your queue to do an Emily LeTella: "Oh, nevermind").
The battery uses PROTONS, not PHOTONS, as the charge carrier. Rather than using large ions as the primary way to shuttle charge across the battery, they use H+ ions (a.k.a. protons) to move the charge. The only photons involved are the virtual photons mediating the electromagnetic force.

- A 200 mAH cell does not have to be discharged at 200 mA or less. The press release said "in a 200mAh device, 9A in 10 seconds" (whatever that means).
- Nothing in the press release mentioned how big this 200 mAH cell is, how much it weighs, or the voltage. That 200 mAH cell might be the size of the end of your pinky finger, in which case a decent-sized battery would be umpteen amp-hours. I can't tell from what's given.
- One can make some educated guesses of the density from the description of the materials; the plastic electrodes probably have a density of less than 1.5, and the sulfuric acid electrolyte is probably 1.2 or less. Contrast this with metallic lead's density of (11.3.)
- The energy density is comparable to lead-acid, but the power density is far higher. If surge discharges can be done at a rate of 45C for 10 seconds, this implies a peak power output of 450 KW from a 10 KWH battery pack. This is equivalent to about 600 horsepower. With the proper power electronics and motors, an electric car with these batteries could eat Corvettes for breakfast. Taking a full charge in 5 minutes means that regenerative braking is a lot easier, and so is quick charging.
This battery is looking like a good part of the death of the non-hybrid internal combustion engine car. With this kind of thing, it won't make sense to use non-electric powertrains any more.--

Risking the wrath of the copyright police, here is the Popular Science blurb (nov 2000 issue). It gives a bit more info. I typed it fast, so beware of typos:
Proton Power
A NEW TYPE of battery that relies on a proton traveling between its poles, rather than bulky molecules, could change how you think about rechargeable batteries. Not only would the new batteries recharge much more quickly, but also they could be recharged an unlimited number of times.
The new protocol polymer battery, developed by Japan's NEC Corp., works more like a capacitor--which stores an electrical charge--than a conventional electrochemical battery. When the battery is fully charged, hydrogen atoms, which each have on electron and one proton, are bound within the cathode material. When an electrical circuit is opened, the electrons split from the atoms and flow through the circuit toward the anode, giving off electricity. The protons flow through an electrolyte to the anode, where they recombine with incoming electrons, forming hydrogen atoms and binding to the anode material. Recharging the battery reverses the process.
The tiny protons speed through the electrolyte quicker than the complex molecules that carry charges in conventional batteries. This means a 12-volt proton polymer battery recharges in just 5 minutes. The battery also generates more power in a shorter period of time--important in, say, an electric motor for a car.
The capture and release of electrons also causes less degredation of the electrodes than the electrochemical reaction of conventional batteries, giving the proton polymer battery a life of tens of thousands of cycles, instead of the hundreds for conventional rechargeables. NEC believes a virtually limitless cycle life--along with the ability to deliver power in pulses--makes the new battery ideal for the recently introduced Bluetooth short-range radio technology, which wirelessly links notebook PCs, mobile phones, and other portable gadgets.
NEC is showing the battery to other manufacturers, but it's too early to tell when (or if) it will go into production.

Sometimes it's best to just let stupid people be stupid.
9mAH means it can supply 9mA for 1 Hour ... 9mA is enough to light a standard LED to half brightness. For an hour.
Please don't offer me a lift in your new car, ''Reality Master''.
Whomever wrote this has little if any clue about the existance of the universe. Either that or they're trying to be vague to keep secrets. It mentions protons being the electron carrier. Hmmm..... where else is a proton the electron carrier? Every metal in the universe. Proton's ALWAYS carry electrons(with the exception of an H+ ion or any other time you completely ionize an element). THe point in that being, they are using electron carrier to confuse you. They may mean differential carrier.
If photons are used to knock electrons off of protons and then a barrier created between the two, it'd ceate one of the largest differentials possible.
But hey, I'm just a physics major.... it doesn't really work in the real world anyways

Humans are slow, innaccurate, and brilliant; computers are fast, acurrate, and dumb; together they are unbeatable
That it is constructed of such simple materials;
As materials such as metals and halogen are not used, the environmental load of the device is reduced (polymer consists of carbon, hydrogen and nitrogen and does not include any of the pollutants used in other batteries).
... and provides such a high energy density, it sounds lmaost infeasible. But then some of the most interesting new technologies I've been reading about in energy creation/storage all sound remarkably simple. Fuel Cells, flywheels and now Proton Polymer batteries.
It'll be interesting to see what new devices come out of the marriage of these technologies. Combine them with low-energy consumption chips such as Crusoe and we could easily be looking at all-day laptops, all month cellphones etc.
"Give the anarchist a cigarette"
A little planning goes a long way...
Actually, lead-acids are probably the worst as far as deep-cycling. Even ones designated as "deep cycle" batteries should never be deep-cycled the way NiCDs have to be. Rechargable alkalines are similar to lead-acids in this respect...
:)
I'd say that if anything, the need to "refill" a lead-acid is a disadvantage. Gel-cells are a wonderful thing.
retrorocket.o not found, launch anyway?
This Article from Carnegie Mellon Talks about how lead based battery cars would be bad for the enviroment. They also talk about how there needs to be a better technology. Well, of all people NEC did it. I'm really excited about this.
Imagine this battery and a transmeta chip also. This Is Great
At last, a UPS that won't outweigh its own volume in neutron star matter...
End of lesson. You may press the button.
These wouldn't make very good laptop batteries because they're too heavy. They would be great for BattleBots because of their high power/weight ratio.
Your design to a real part online: Big Blue Saw
The press release claims that the energy density is the same as lead-acid batteries. We can presume that is for weight/unit volume. No clear indication of the weight of this unit though... I would presume much lighter (I associate lead with heavy) and though this would be it's biggest advantage in many cases (esp. cars), don't forget that Lithium/Ion and even Nickel Metal Hydride have higher energy density (erg/vol) than lead acid...
I think that the speed of recharge might be most useful, as e-cars would not require an overnight charge. 5 Minutes at a servo (with a thick enough cable to carry the amps) wouldn't be so bad.
20min@9A, 2min@90A 15sec@900A.
The battery might actually be able to take the 900A, if you could design it so that the wiring wouldn't melt in the process. The most probable approach for most consumer items would be between the first 2 options. (charging a 12V battery at 90A is actually doable with household current. It would translate to ~10A at 120V, but a power supply that could do that would be rather bulky -- you're talking a 1100W power supply. It might be doable as a base station. The lower range is more likely for a portable. The 900A range might be used for industrial/military applications.)
If the connectors for the battery were standardized, you might actually see units in the airport where you'd pay $2 to charge your battery in 2 minutes or less. (Images from half-life keep flashing in front of my eyes (HEV charging units)).
If they go commercial, these units might actually be made with cheap Titanium cases because a puncture could result in a catastrophic energy release.

try { do() || do_not(); } catch (JediException err) { yoda(err); }
And this is an important consideration in hybrid electric vehicles.
In my final two years of college (ME degree,) I got involved in a project to build a hybrid. We participated in the 1995 Hybrid Electric Vehicle Challenge, and won our class. I drove this car (a converted Saturn SL-2) all around California.
In watching the performance of the car, we noticed that we used power from the batteries in a very "spikey" manner. The engine would drive the car, then stepping on the pedal would cause a > 300A draw from the batteries. This would drop to less than 30A in about a second. This is from a 180V (nominal) battery pack.
As for energy density, that's the problem hybrids solve. The energy for this car came from the fuel. We never recharged the batteries from the grid, only by running the engine, and almost always while driving. We even drove the thing from Fresno to Yosemite valley, and put more energy into the batteries than we removed.
I'm rambling, I see, but my point is that these batteries would rock in a hybrid meant for performance. While ~350 lbs of these things would probably send the car ~4 miles before running out, a hybrid would replace the energy before you ever got that far. That is the beauty of hybrids - use the great acceleration of electric motors without having to cart 3000 lbs of lead to get anywhere useful.

As long as you didn't drain it, A furby-sized battery could jump start a car (but you'd still need 2-gauge jumper cables to connect it!). If you shorted it out with 12Gauge (extension cord) wire, you could probably burn off the insulation in under 10 seconds. Now think what would happen to your thigh if you stuck one of these batteries in your pocket and shorted it out on your keys -- We're talking instant branding here (not to mention the hole burnt in your pants).
I once saw a friend of mine fix a car without taking off his wedding ring.
It was a Ford, with an external starter solenoid. He shorted the positive terminal on that to ground and lost the finger.
If you heat it fast enough, gold will glow red before it drips away and breaks the circuit.
Fire and Meat. Yummy.
I love cars. Old muscle cars, big-assed V8 engines sucking back huge amounts of gas. I love the mechanism, and I love the elegance of them.
I've always been someone who has put down the electric car. Not for loss of that romance - oil is evil, but until now, there's been no practical replacement for it.
I look forward to the improvements and things that will definately come of this NEC innovation. I think we're finally at a stage where the electric car is going to become practical.
Now, we've gotta start building nuclear power plants so that when people start plugging in their cars to charge them, it won't kill the country's electrical grid.
Fire and Meat. Yummy.
Second, this is really a device for high surge power output. That's a specialized application. The classic in that market is the PolaPulse battery inside each Polaroid film pack. As others have pointed out, this new device is down there with lead-acid on energy density. The NEC article mentions Bluetooth devices as an application. They're thinking of "somnolent computing", devices that sleep most of the time.
Cruddy battery time is a big factor in my choice to not have a laptop for personal use. I fly overseas occasionally and it's always a disappointment when my work laptop runs out of juice or when on a trip wondering when I can get the time to charge up the batteries again.
The power density is high for this material, NOT the ENERGY DENSITY. Power density is a measurement of high-current discharge per unit of time per unit of volume(or weight).
The power density for these devices is in excess of 1,000 Watts/Kg, much higher than the few hundred for lead acids/NiCd's etc. Although--- the energy density of the NEC proton batteries is still rather dissapointing at 10-15 WattHours/Kg compared to the 20-30 WattHours/Kg of lead-acids'. But since it's such a new technology IMHO there is much prospect for improvment in this area, and getting competitive(in terms of batteries) energy densities out of these things is only a matter of time.
There is an article in the "Nikkei BP AsiaBizTech" site here: http://www.nikkeib p.a siabiztech.com/nea/200008/cmpo_108677.html
- "Hear that?! The percolations are imminent! Cease your ingress!"
Fast charging, fast discharging, add these babies on top of the main battery in your electric car (or hybrid) and you have the potential to regain maybe 80% of the energy when you stop and use it to start moving again.
In city driving, that means probably doubling the range of an electric car, and not having to worry too much about low mass for efficiency. This means having an efficient city car that carries enough batteries for long-range highway use. Sweeeeet.
Sure, there are plenty of other applications for something halfway between a battery and a capacitor, but this is the one I bet you're most likely to end up using, and the one that saves you the most money.
--------
This battery technology has high power/weight and mediocre energy/weight. To me that sounds ideal for applications where you have a steady low-power energy source and want short bursts of much higher power from time to time. Where is this, we ask:
1. Small planetary exploration robots: charge slowly off the solar cells, then use a burst of power to move/dig/analyze/transmit, then go back to sleep and recharge.
2. Similar story for remote sensing -- run the sensors and slowly charge the battery of a small solar cell, then use a burst of power to run the radio transmitter and report
Steve
Hmmm, 9A in 10 sec = 25 mAh, that is more than the 20 mAh battery capacity. There is something wrong here !
RFC1925
But unfortunately, due to the conspiracy, we'll never get this kind of technology. :-(
Say what? Are you sure you aren't just talking out your ass? Go dig up the issue of Wired magazine from around April 1999 or so. They've got an article on electric drag racing in there, and the reason electrics are in a different class is because they blow away fuel-powered racers. Fuel-powered dragsters have no chance against an electric, because electrics can dump so much energy so quickly.
The reason we don't have electric cars on the highway is not because of strength, but because of duration. You can get great performance out of an electric vehicle for half an hour or so, and then it drops way off.

A reality check guys,
This document is dated the 30th of March this year (Probably available to the world on the 1st of April!) and claims that the technology would be presented on the 4th of April in Japan with actual products becoming available in October this year...
If this is as big as it sounds the whole world would be raving about it, no i think this is a April fools joke.
Damm shame.... *sigh*
Every time I see an article about the next "super battery", I wonder if people have considered the safety issues of batteries with high energy densities and high discharge currents. Under the right conditions, some batteries can explode, catch on fire, go into thermal runaway while being charged, or cause burns when shorted. Lithium ion batteries are already banned in some applications.
