Its current capacity is 20Ah and output density is about 1,000W/kg. Toshiba is currently manufacturing a 4.2Ah cell with an energy density of about 67Wh/kg for electric bicycles and other applications. The company improved the energy density by about 1.5 times by replacing lithium cobaltate previously used for the positive electrode, it said.Source: Tech-On
Toshiba has already developed a 3Ah high power cell with an output density of 4,000W/kg for hybrid cars and is now shipping its samples.
