Toshiba launches 20Ah-HP SCiBTM Lithium-ion Rechargeable Battery Cell

Cell delivers both high energy and high power and its wide applications include vehicles, industrial equipment and energy storage systems.

Toshiba Corporation, a company dedicated to advancing carbon neutrality through its technologies, products and services, recently expanded its SCiBTM product offering with the launch of an innovative 20Ah-HP lithium-ion rechargeable battery cell that delivers high energy and high power at the same time.

The market wants batteries that deliver both high-energy and high-power characteristics, but until now this has required a trade-off for lithium-ion rechargeable batteries. In an EV, for example, a high-energy battery allows the vehicle to drive further on a single charge—but it lowers power input and output and extends charge times. Toshiba drew on its knowhow in current high-energy and high-power products to develop a new cell that successfully combines the advantages of both.

Product Features

1. Excellent heat suppression
   Compared to Toshiba’s current 20Ah cell, the new 20Ah-HP cell delivers 1.7x higher input and 1.6x higher output, realised by an approximately 40 percent reduction of resistance in the cell. This improvement efficiently suppresses heat generation when a large current is applied, allowing design of a simpler cooling system. For example, depending on the customer’s system, water cooling can be simplified to forced air cooling, and forced air cooling simplified to natural cooling. The lowered resistance also reduces over voltage, allowing the cell to function in a wider range of state-of-charge (SOC).
2. Long life
   The new 20Ah-HP cell achieves a longer life than the current 20Ah cell by suppressing heat during continuous charging and discharging, due to its lower internal resistance. Under the test conditions shown in figure 1, the cell maintained almost 100 percent capacity after 8,000 charge/discharge cycles, while the capacity of the current 20Ah cell decreased by approximately10 percent.
3. Compatibility
   The new 20Ah-HP cell delivers improved input and output power but maintains the same size as the current 20Ah cell, allowing current customers to easily upgrade to the improved performance with the same module pack.
