Toshiba announces better battery for 2006: March 2005:  "Toshiba Corporation today announced a breakthrough in lithium-ion batteries that .. 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 improvements in energy density. ..  the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store vast amount of lithium ions, without causing any deterioration in the electrode. ..

The battery has a long life cycle, losing only 1% of capacity after 1,000 cycles of discharging and recharging, and can operate at very low temperatures. At minus 40 degrees centigrade, the battery can discharge 80% of its capacity, against 100% in an ambient temperature of 25 degree centigrade).

Toshiba will bring the new rechargeable battery to commercial products in 2006. Initial applications will be in the automotive and industrial sectors .. tTe battery's advantages in size, weight and safety highly suit it for a role as an alternative power source for hybrid electric vehicles."  This is faster than expected; nano particles to accelerate charge and discharge and improve density have been reported in universities, while this is an announced product.
