2021/04/30

Summary

  Based on a technical presentation at the 12th International Rechargeable Battery Expo - Battery Japan (March 3-5, 2021, Tokyo Big Sight), this report introduces the principle features and future strategy of the SCiBTM lithium-ion rechargeable battery, which Toshiba Corporation (Toshiba) has developed and produced independently since 2008. (Speaker: Ms. Asako Satoh, Cell Technology Executive, Battery Division, Toshiba Corporation)

  The electrodes of the latest lithium-ion batteries are made of a variety of materials on the positive electrode side, but graphite is nearly a standard for the negative electrode. In contrast to this, SCiBTM has been given a unique feature that sets it apart from other batteries by using a distinctive material on the negative electrode side.
