Toshiba Corporation today announced a lithium-ion battery that can be recharged to 80 percent of its capacity in just one minute. This is approximately 60 times faster than the typical lithium-ion batteries used in handhelds and smartphones today.
According to Toshiba, the negative electrode in this battery is made up of nano-particles. This prevents 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 fast recharging characteristics of this battery are not its only performance advantages. It also has a long life cycle, losing only 1 percent of capacity after 1,000 cycles of discharging and recharging.
In addition, it offers a high energy density. The prototype battery is only 2.4 inches long, 1.4 inches wide, and 0.15 inches thick. (62 mm by 35 mm by 3.8 mm) and has a capacity of 600 mAh (see picture at left).
Toshiba did not make a price comparison between this new type of battery and current ones.
Toshiba’s new rechargeable battery will start appearing in commercial products in 2006. Initial applications will be in the automotive and industrial sectors, but considering its advantages over current lithium-ion batteries, it will surely be used in future handhelds and smartphones.
