Plastic Batteries Coming Soon?

Roland Piquepaille writes "Engineers at Brown University have built a prototype of a hybrid plastic battery that uses a conductive polymer. The system, which marries the power of a capacitor with the storage capacity of a battery, can store and deliver power efficiently. For example, during performance testing, 'it delivered more than 100 times the power of a standard alkaline battery.' Still, it's unlikely that such a device can appear on the market before several years."

Most devices, from light bulbs to computers, require a certain voltage to operate. At the same time, you want to be sure your battery can provide sufficient current -- can it supply electricity fast enough to keep the device going.

      So that's power, a rate of energy. You can convert it into Joules per second.

      The other thing you're interested in is how long your battery will power your device. For that you need to know how much energy it stores, not just how fast it can release it. That is, Joules or, more commonly in batteries, Watt-hours, miliwatt-hours or, assuming the rated voltage, amp-hours or miliamp-hours.

      It's the same with power plants. Your power plant might be rated for 500 megawatts, meaning it can supply 500 megawatts, we assume pretty much constantly, but your power bill will charge you for kilowatt hours.

        * Current (I, in Amperes A)

      However, these units only measure energy at a single point in time. But we're dealing with finite energy sources. We need to introduce another unit:
        * Time (T, in Hours h, or in Seconds s)

      Let's take a new look at your formula, adding a variable for time:
        P * h = V * I * h

      Now, let us consider a the same NiMH AA battery that you looked at earlier. To know how powerful that battery is, we need two know two things:
        * Its cell voltage: 1.2V
        * Its capacity rating: 2.5Ah (normally quoted in mAh / you'd see 2500mAh in the specs)
        * It's maximum power drain: 2.5A

      These two numbers tell us that roughly, this AA battery can deliver its quoted voltage of 1.2V for one hour if the current drain is 2.5A.

      P1 = 1.2V * 2.5A * 1h
      P1 = 3W * 1h = 1.2V * 2.5Ah
      P1 = 3Wh = 1.2V * 2.5Ah

      This battery can power a device with a power draw of 3W (equivalent to a current draw of 2.5A at a voltage of 1.2V) for one hour. It has a capacity of 3Wh (equivalent to a capacity rating of 2.5Ah at a cell voltage of 1.2V).

      Let's assume that these are the specs for our new battery:
        * Its cell voltage: 1.2V
        * Its capacity rating: 2.5Ah
        * It's maximum power drain: 250A

      Now, this is where you get it wrong. What we're doing is increasing the power drain by 100, not increasing the capacity by 100.

      P1 = 3W * 1h = 1.2V * 2.5A * 1h

      P2 = 3W / 100 * 100 * 1h = 1.2V * 2.5A * 100 * 1h / 100
      P2 = 3W * 1h = 1.2V * 250A * 0.01h
      P2 = 3Wh = 1.2V * 250A * 36s
      P2 = 3Wh = 1.2V * 2.5Ah

      So, the new battery could power the 3W device for 1 hour, or a 300W device for 36 seconds.

      Now, in reality, this new battery/capacitor hybrid is likely to have a far lower capacity rating (quoted in mAh on the box) than your typical NiMH AA cell. Also, the typical AA cell has a higher maximum power drain, which can be increased further by cooling the battery as you discharge it.

      Also, in the real world, things don't work out quite as nicely as in these equations - there are power losses that vary based on a lot of factors. How fast is the battery discharged? How hot is it - and the more quickly you discharge it, the hotter it becomes, the less efficient it becomes.

      Granted ExxonMobil is prevented from behaving this way, but ExxonMobil is essentially a ginormous middleman in the way that McDonalds is. The producers are the problem here, not the refiners. To follow the McDonalds parallel, you're looking at the resteraunt when you should be looking at the cattle ranchers.

      Think about it rationally: if Ford had found a way to make a regular car get 80mpg using some Magic Carburetor Technology (to reference the urban legend in its 70's form), they could make a killing in the marketplace.

      In 1940, Tucker released an automobile that got almost 40 miles per gallon. His top of the line model, the Tucker '48, got 36. Ford's best fuel economy in 2006 was the Ford Escape Hybrid, which got 33 miles per gallon. Do you honestly believe that there's been no progress in the last 60 years?

      Besides, 80 mpg isn't actually unreasonable. The problem is getting 80mpg in a car at over 25 miles per hour, in a vehicle with amenities that will sell (the weight of the car is significant,) which is built in a way that if there's an accident, not everyone dies. To give you a sense of scale, Suzuki makes and sells a motorcycle that gets 216 miles per gallon. On one 11-gallon tank, you can make it from Las Vegas to Washington DC. That's not fringe science.

By that time, the new laptops have increased in power and performance, so I tend to want to weigh the cost of a new battery vs just getting a new laptop.

      1. Toshiba T1910CS, 4 MB of RAM, DOS/Windows 3.1, lots of handy Toshiba utilities, such as Windows 3.1 or DOS floppy disk creator, so you can give everyone a set of DOS or Windows 3.1 installer floppies. Upgraded everything, so it has Internet Explorer and can dial up using the PCMCIA modem, and surf the web. Windows 3.1 did not do that unless upgraded (a lot).

        Screen now almost gone, very dim, and battery is dead. Will run, and you can see the display if you turn off all the room lights. I can run Arachne on it, and some have installed linux, the link above shows that.
      2. Toshiba 4015CDS, 32 MB RAM standard, upgrade to 160 MB about $50.00 (friend couldn't use the stick).
        Windows 98, 4 GB hard drive. Will run my livecd linux (see screenshots, below) directly from the hard drive, using loadlin and some menu batch files, completely freeing the CDROM Drive. Battery is dead. New one probably over $120.00 delivered. Laptop when new was (gasp) $2100.00. I buried the receipt in a time capsule to be opened in 100 years (just kidding).


      One advantage to the 4015CDS is that it can run linux which is easier on the hard drive (and the battery), than Windows 98, now an unsupported OS. PCMCIA modem gives good dial-up performance, usually 48000 bps or higher. Does 800x600x24, display still works good.
      Still, considering the cost of the battery, a new laptop might be worth it. Windows XP would be nice to run for music and photo's , but I would not really want to let it out onto the internet.

Yunick's wondrous new engine is dirty and difficult to maintain, but the only POSSIBLE reason why it isn't being used today is that every CEO in Detroit, from Lee Iacoca back then through Bill Ford Jr today, would rather teeter on the brink of bankruptcy with billions of dollars in losses, than risk offending their secret masters in OPEC. Yeah, that makes perfect sense.

      What? All I was doing was pointing out originally that there was at least one verified advanced carburetor system that got much better than normal mileage. And was very open about the possibly why's why it wasn't used much. there was another one way way back as well, the Pogue carburetor. Carbs in general have poblems that have been overcome with fuel injection, smokey's came just hen the industry was going to fuel injection, which gives somewhat better mileage and allows a lot better timed delivery. They do the fuel part for vehicles with emissions in mind as well. Smokey was clear his needed expensive lubrication and more advanced engineering and materials, that is primarily the reason they didn't go to anything like that, but that doesn't negate the fact that he did build it, and it did work and at the time was an amazing difference with what was currently out there. As to any high level conspiracies or whatnot, you get what you see, especially with the detroit car bosses, behind the curve a lot compared to the japanese and european car companies because gasoline remained so cheap in the US most likely. That's a guess on my part. US drivers wanted huge engines, bg sound, out of the hole performance and didn't care to mych untilrecently about mileage except for a brief period after the OPEC embargo. We had european and japanese cars hit with much better mileage and designs way before it was common in detroit, fuel injection, overhead cams, turbocharging, etc. In the more modern era we have seen it with stratified charge and hybrids, etc. Now that basically all the car companies are global and own each other, I don't think you can even classify them as being all that regional or national. I do think though you might be seeing a resurgence of the smaller companies as more advanced features are developed. It seems to go in cycles like most others-way way back we had a lot more companies, then consolidation, now we are seeing the very small companies really coming out with some interesting stuff, like AC propulsion with the two stage hybrid concept (the detachable ICE part) or the tesla car. That there will be a much bigger variety of types of cars though is indisputable now, we will be getting a lot more options, flex fuel, more turbo diesels, etc. Honda just announced they will be pushing a much cleaner diesel starting next year IIRC, and a bt more battery design tweaking and we will be seeing comercial plug in hybrids, which really opens up some good mileage areas tat still maintain "performance" and range.

      To summarize, there were good mileage carbs that didn't make it into mainstream use, why they weren't adopted is something of a red herring, *aspects* to improved designs get adopted and modified and morphed around. We are seeing a resurgence of variable valve timing now, because altough the concept was sound way back, they couldn't pull it off with reliability, now they can. and etc.

  43. Plastic Batteries That Last 100x Longer? by electrogeek_dot_com · · Score: 1

    Yeah I can see it now. Duracell will roll out a new plastic battery that lasts 100x longer then their standard batteries so in turn consumers will need to buy Duracell batteries less often. This in turn will drive their profits down due to slower sales. Yep. I'm sure they'll get right on that. Then they can start work on their line of nuclear batteries which never need replacement or recharging. Sounds like a plan.

  46. Uhm, no by joto · · Score: 1

    Currently there are three kinds of rechargeable batteries used for electonics and toys: [NiCd, NiMH, Rechargeable alkaline]

    Uhm, no!

    You forgot some very common types:

    • Alkaline - Most common. (or are all alkalines rechargeable?)
    • Li-Ion - Expensive, rechargeable, with high energy and power. Non-standard sizes only. Used in cellphones, digital cameras and other expensive high-tech gadgetry that ared used often, requires a lot of power, and must remain portable.
    • Litium - Expensive, non-rechargeable, with high energy and power, and long shelf-life (> 10 years). Not rechargeable. Cells are 3 volt, so standard, AA, AAA, C, D cells cannot be replaced, although 2 of them in series can. Comes as 9 volt batteries and as their own weird sizes (CR123A being the most common).
    • Heavy duty - The cheapest kind of battery. Has long shelf-life. Not rechargeable.
    • Lead - Well perhaps not commonly for electronics and toys, but... does the "portable" speakers for my mp3-player count?

Congratulations!

    On a related note, coal -- having one of the highest energy-densities of any chemicals known -- has been banned, since it must also therefore be a bomb. Likewise with wood. Anyone found transporting wood on their person into a government building or office will be shot on sight as a terrorist. Upon realizing that hydrogen, by virtue of its capacity to fuse releasing energy, has a high energy density too, our handsomest politicians have seem to it that water and all other hydrogen-containing compounds are banned. It was then helpfully pointed out that all matter is also energy, and therefore has enormous energy density. All matter is therefore bombs. Anyone found purchasing matter will be requird to have the appropriate paperwork for dealing with explosives. Unregistered transport of matter-bombs is a terrorist act of the worst kind, and will be tortured to death in a CIA information-collection centre until saftety happens.

    I was talking about rechargeables, so Lithium, heavy-duty, and regular alkaline don't count.


    Not sure how I spaced on the Lithium-Ion batteries - I was probably thinking about things that can replace AA/AAA, but obviously cellphones and laptops are using the things, and they work a lot better than NiMH in terms of memory effect.


    I left out lead-acid on purpose - how big are the ones for your MP3 player speakers? I do have a friend who uses them in his portable stereo system, but it's mainly "portable" with a hand-truck, uses a couple of motorcycle batteries, and puts out enough sound to cover a whole dance floor for a couple of hours.

    I didn't know about Lithium Polymer batteries - interesting to hear about them. I've had a number of applications which needed 3V or more, so LiOn or LiPo would work. Unfortunately, NiMH works well enough for most AA/AAA applications that it's pretty much crowded out the rechargeable alkaline market, and I've had trouble finding more AAA for things that need low power for months, though AA are still usually around.
