AIST, Ishihara Sangyo Develops Advanced TiO for LiI Battery Electrode

National Institute of Advanced Industrial Science and Technology (AIST) and Ishihara Sangyo Kaisha announced on Monday they developed high capacity titanium oxide negative electrode material for lithium ion battery, which has higher capacity with lower cost compared with lithium titanate.

The titanium oxide is composed of hydrogen, titanium and oxygen. The charging and discharging voltage is 1.55 volt as lithium titanate and the capacity is 225 milli-ampere hour per gram of oxide, which is around 30% higher than lithium titanate.

Due to no use of lithium, the production cost of the titanium oxide is lower than traditional material. AIST and Ishihara Sangyo expects the technology will contribute to a high capacity, long service life of lithium ion battery and price reduction for electric vehicle.
