Toshiba's new one-minute-recharge battery PDF Print E-mail

Toshiba has announced what sounds like a big advance in Battery technology with a Lithium Ion battery that recharges to 80% of capacity in a minute; only loses 1% of its capacity after 1000 cycles; among other attributes that make it particularly suitable for hybrid vehicles. The press release is unusually informative, with some neat charts for comparing it with other batteries. I think the potential for a fast recharge has been overlooked in most of the reports on this battery. Sure its great for regenerative braking, but it also eliminates a lot of the range arguments against pure electric cars. At a sweep it creates the potential for doubling the range, since one could assume recharging at the destination (an unreasonable assumption if a recharge takes a few hours). Similarly, for long journeys a one or two minute break every hour is not an unreasonable expectation. The gains compound, i.e. if a car (or scooter or bike) only has to travel one hour between recharges, then the mass of batteries to be carried can be reduced, which means less energy needed to carry the batteries around, and so on. I'd love to get a set of these for my electrified pushbike, it would make it practical for a LOT more uses than currently.
