Toshiba Battery Charges In 10 Minutes
Slatterz writes "Toshiba has unveiled a battery prototype that offers a 90 percent charge capacity in just 10 minutes. The Super Charge Ion Battery (SCIB) is capable of handling 5,000 to 6,000 recharge cycles, compared to the typical 500 offered by standard lithium-ion batteries. The new battery is composed of a durable material that offers a high level of thermal stability and prevents overheating."
Will this battery explode or just burst into flames?
Even better, this article. More tech specs.
Never approach a vast undertaking with a half-vast plan.
Yes, there is:
Typically, the last few % take a as long as everything before together. Its just that the nature of the chemical reactions involved: During the charge, the battery voltage increases. The charger OTOH cannot push more than 4.2V (for normal batteries) respectively 3.7V for LiFePo4, in order not to damage the cells. This means that effective voltage drops during the charge, and duringe the last bits of capacity, there are only some 0.1V left. Add internal resistance, and its clear why it cannot fill up completely fast
Other comments suggested downrating, but that doesnt really make sense: as long as you leave it in the charger, it will gain charge for a while, so the real capacity is truely higher.

It stinks, but who knows - it may just be a fine cheese or chocolate.
On the other hand, the Vaporware Meter is off the charts, and the "durable material" and it's claims broke the poor Economic Feasibility Meter.
How could any geek not want a battery like that?
Is it just my observation, or are there way too many stupid people in the world?
How about, "This flashlight charges to full in 10 minutes. If you leave it plugged in for another two hours, you get an extra 10% 'superboost' charge!"
This is marketing language we're talking about, after all.
You're special forces then? That's great! I just love your olympics!
only 500 cycles, really? that seems a little low. do they mean that after 500 charges the battery begins to decrease in capacity, or that the battery will start to fail completely after 500 charges? because that seems really really low to me.
i mean, most rechargeable batteries today are Li-ion batteries, right? i just wanna know how many recharges i have left on my PSP.
does it help if you make sure to plug the battery back into the charger before it's out of charge? what can you do or not do to help preserve the capacity and life-span of a li-ion battery?
Li-ion batteries are usually limited by 'calendar' life, not charge cycles - they start losing capacity the moment they are packaged at the factory and generally last a couple of years before they become too weak to use.
However, there are some strategies to extend their life:
1. Keep them cool (but not frozen)
2. Keep them at around 40% charge
Now, this probably isn't too useful for batteries that you are actively using - however, if you have spare lithium batteries lying around that you aren't using at the moment you might want to drain the charge to about 40% and zip them up in ziplock bags and put them in the fridge until you need to use them (check it once in a while to make sure they haven't drained to zero charge because that can kill them).
Also, this means that you should avoid letting your Li-ion batteries get hot unnecessarily, like leaving them in a hot car in the summer.
This is a good reference http://www.batteryuniversity.com/parttwo-34.htm
And you won't need one.
Let's use Australian numbers (because I know them):
Available voltage from a standard wall outlet: 240v
Available amps: 10
Using Ohms law (and assuming resistance will remain roughly the same), I should be able to get nearly 100A @ 24v using a step-down transformer. Most laptops have an input of around 19v. As long as the leads can handle the amperage, it shouldn't be an issue.
It's the leads that will be an issue. IIRC, cars need 50-80A @ 12v to start. The leads that come off the battery for the starter motor are pretty big, and they only need to handle that current draw for up to 10 seconds...
Hey, I just removed the "citation needed". You're good to go.
