Toshiba recently announced the launch of a new Li-Ion battery that could be recharged to 90% within 5 minutes. Toshiba plans to initially make the quick-charging Super Charge ion Battery for electric bikes, forklifts, construction machinery and other industrial use. It can work in temperatures as low as minus 22 degrees Fahrenheit. Toshiba also said its new battery, which is estimated to last 5,000 charges, is unlikely to rupture or catch fire, problems that have beset some lithium-ion batteries used in laptops. The full report can be found here: http://www.msnbc.msn.com/id/22240865/ I am a bit sceptic about this announcement, although such a battery would be great! What have the battery experts among you to say about the news released by Toshiba? Just plain PR or some truth behind? Twike 890

Hi, news like this pop up every now and then but: a) What kind of power socket can deliver such vast amounts of energy in such a short time? I don't know of any. b) Who has the power plant at home to prevent a blackout in your whole street when charging this battery? I really like this PR nonsense.

They're actually selling small quick-charge battery packs now for power drills and the like. But as I think Franko30 was suggesting, it's not practical to quick-charge a battery pack at home which could power your car, motorcycle etc. That would take far more amperage than household current provides. One possible solution, which has been suggested for use of the EEstor ultracapacitor (if that turns out to be real), is to have two battery/capacitor packs; one is left plugged in at home overnight, and the other is in your car (motorbike, etc.) To charge your car quickly, you'd run a thick power cable between your car and the stationary unit. Obviously the problem with this solution is you need two battery packs instead of just one, and battery/capacitor packs powerful enough to run a car are gonna be expensive.
