Toshiba has developed a lithium-ion battery with a short
rechargeable time and an energy capacity 'equal' to those of
conventional lithium-ion batteries. Toshiba's new battery,
according to the company, can recharge 80 percent of the
battery's energy capacity in one minute. This is approximately
60 times faster than the typical Li-ion batteries. The energy
density is 150 to 250 Wh that is equal to the lower range of
energy densities existing lithium ion batteries have. Toshiba's
prototype battery has a capacity of 600mAh and is 8mm thick,
62mm high and 35mm deep. The battery was demonstrated in a hard
disc music player for about 10 minutes by charging 5 milliwatts
in 5 seconds. With the stable electrolyte solution, the battery
is expected to operate at temperatures of -40°C, though Toshiba
maintains that it is limited to 80 per cent of capacity in such
conditions, compared to 100 per cent at 25°C. The battery also
has a long life considering the company holds that it loses only
one percent of its capacity eac
