Toshiba Corporation has expanded its SCiB™ 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 cell is now available to order worldwide.
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.
Heavy load applications
The cell is ideal for heavy-load applications where high power input and output are essential, and for situations where battery cells must suppress heat and operate continuously, such as rapid charging of commercial vehicles, regenerative power systems for rolling stock, and industrial equipment. The cell is the same size as Toshiba’s current 20Ah product, allowing current customers to easily upgrade to the improved input and output power with the same module pack.

Product Features
- 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, realized by an approximately 40 per cent reduction of resistance in the cell.
- 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.
- 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.
Applications
Toshiba expects to see the new cell deployed in automobiles, industrial equipment, and storage battery systems. Some examples include drive power supply and emergency power supply for railways, regenerative power supply for harbor cranes, electric ferries, hybrid buses, trucks, hybrid electric vehicles and plug-in HEVs, alternatives to lead-acid batteries and storage battery systems.
