Report: Toshiba Boosts Discharge Density of SCiB Li-ion Battery, Plans Full-Scale Commercialization in the Fall
13 April 2009
The Nikkei reports that Toshiba has improved the discharge density of its SCiB Li-ion battery to 3,900 W/kg. Last year, Toshiba described the development of a 3.0 Ah high-power version of the SCiB with 3,600 W/kg output specifically for hybrid electric vehicle (HEV) applications. (Earlier post.)
...because it can be charged as fast as in a minute and a half, instead of more than 10 minutes, it is suited for plug-in hybrids, according to Toshiba. The battery also has a long life, capable of withstanding more than 10,000 recharges. The firm has started shipping it to major Japanese, US and European automakers on a trial basis.
In addition, Toshiba has developed a lithium ion battery with a high energy density for electric vehicles, given that discharging power over a long duration trumps high output in such applications. The company hopes to begin sample shipments of the battery this fall.
In February, Volkswagen AG and the Toshiba signed a letter of intent to cooperate for the development of electric drive units and the accompanying power electronics for Volkswagen’s planned New Small Family. Volkswagen and Toshiba said then they were planning the development of battery systems with a high specific energy density for the next generation of electric vehicles. (Earlier post.)
Cannondale Sports Group, a global provider of branded bicycles and a division of Dorel Industries, Inc., selected the SCiB to provide the power battery module for a new electric bicycle for the North American and European markets. Toshiba’s SCiB 24V/4.2Ah module will debut in the Tailwind, a new electric bicycle Cannondale Sports Group is bringing to market under the Schwinn Bicycles brand. (Earlier post.)
Toshiba currently produces 150,000 SCiBs a month at its plant in Nagano Prefecture, and plans to start constructing a factory in Niigata Prefecture by this fall to coincide with its full-scale entry into the field of automotive batteries. Toshiba is planning for an initial 2 million units a month upon start-up, and hopes to boost monthly output to 10 million by around 2015.
