Toshiba Announces One-Minute-Rechargeable Li-Ion Battery
"Toshiba Corporation today announced a breakthrough in lithium-ion batteries that makes long recharge times a thing of the past. The company's new battery can recharge 80% of a battery's energy capacity in only one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today, and combines this fast recharge time with performance-boosting improvements in energy density."
Wow! 8O While the Toshiba press release goes on to say that this technology will be focused initially within the automotive and industrial sectors, it also clearly states that mobile devices will be targeted as well. This could be the most significant breakthrough I've ever seen with regards to rechargeable batteries! I just hope that when this eventually does trickle down to PDAs and Smartphones, that Toshiba will share the love with all manufacturers. So what do you guys think?

24 hours too early? I hope it's true though!

While this looks pretty amazing, I can't help but think about what my dad always told me..."If it looks too good to be true, it isn't real."
This has me wondering.

Hmm...600mah in 1 minute. That charger is gonna have to put out better than 36 amps. I can't wait to see how they handle that problem, but then of course thats probably why they are aiming at the industrial/automotive sector.

i dont see any possibility that this technology will be used in handhelds.
i want to add a simple math to what locksmith wrote:
under 4 V voltage, 36A of current(!!!) means 144W/h of power !
man, what kind of a pda will carry connectors which will handle this much power and heat emited by this current!

I'm glad there are people out there like locksmith and kowalski who understand all of these issues. My first thought was a loud "wow!" But your doses of information help me separate the hype from the reality.
Is it possible that Toshiba has somehow suspended the laws of nature and this super-rapid charging can take place without melting anything within three feet of the charger?

Just because it can be done in one minute does not mean it has to. 10 minutes are good enough (meaning 10 times less current), and even just the extremely low degradation rate (1000's of cycles) would be good enough, even without rapid charging.

It does say 80% though. Could they somehow make the last 20% actually hold most of the charge :idea:?

Ummm... then the 80% wouldn't be 80%, would it?
