Toshiba SCiB™, a highly safe rechargeable battery, has six outstanding characteristics.
What is SCiB™ ?
The Toshiba SCiB™ is a rechargeable battery with outstanding safety performance.
By using newly developed oxide-based materials, SCiB™ is designed to have a structure that holds high resistance towards thermal runaway resulting from short circuiting caused by physical stress .
Furthermore, SCiB™ has various superior characteristics, Including a long life exceeding 15,000 charge / discharge cycles, rapid charging time of 6 minutes, input / output current densities comparable with capacitors, and operational at temperatures as low as -30 ° C.
- Rechargeable battery with high safety and long life
- Rapid charging and low-temperature operational
- Well proven in various fields
SCiB™ provides a long life of over 15,000 * charge / discharge cycles, rapid charging, high input / output power performance and excellent low-temperature operational, all while maintaining a high level of safety.
1. Safety : uses highly safe lithium titanium oxide (LTO)
2. Long life : over 15,000 cycles *
3. Low-temperature-operation : can be used at Temperatures as low as -30 ° C
4. Rapid charging : rechargeable in 6 minutes *
5. High input / output : chargeable at high current and provides high current output
6. Wide effective SOC range ** : provides a large available capacity
* Measured with a particular single cell under specific conditions
** SOC: State of Charge
There is very low risk of fire or explosion from internal short circuit caused by external pressure. therefore, SCiB™ is suitable for various applications requiring high levels of safety and reliability, such as automobiles, industrial equipment and stationary systems.
2. Long life
Only a small degree of capacity degradation occurs even after more than 15,000 cycles * at charging and discharging currents of 3C.
SCiB™ has less impact on the environment because it requires low maintenance even when it is used in applications that perform frequent charging / discharging such as large-scale storage battery systems.
* Measured by Toshiba using a 20Ah cell under specific conditions
3. Low-temperature operation
SCiB™ exhibits low cycle-life degradation even when it is charged and discharged at -30°C. Thus, SCiB™ can be used for applications that require exposure to low temperatures, such as refrigerators or island applications in cold climate.
4. Rapid charging
Frequent rapid charging does not cause significant deterioration in the SCiB™ performance. Thus, the use of SCiB™ allows automobiles, buses and other vehicles to be charged as quickly as refilling a gasoline car.
5. High input / output
SCiB™ can be charged and discharged at high current rate. Thus, SCiB™ can store a large amount of regenerative energy in a short time as produced by a train or an automobile during braking and supply a large current to the motor during vehicle start-up / acceleration.
6. Wide effective SOC* range
SCiB™ exhibits stable input / output characteristics over a wide SOC* range, and can be charged to 100% and fully discharged to 0%.
This reduces the amount of batteries and space necessary for a system.

Manufacturing and R&D center : Toshiba Kashiwazaki Factory
SCiB™ rechargeable batteries are developed and manufactured at Kashiwazaki Factory.
Kashiwazaki Factory is designed to provide great flexibility in changing its floor plan in much the same way as the latest semiconductor facilities. Thus, Kashiwazaki factory can respond to changes in production plans in a timely manner according to demand and model changes.
Moreover, the factory reduces the energy consumption necessary to run air-conditioners and maintain dry air by optimizing and minimizing the locations of clean areas and dry areas. Consequently, this environmentally friendly factory consumes roughly one-fifth the energy of Toshiba's existing factories.
