Si-dominant Li-ion company Enevate targeting power tool market

Green Car Congress

Enevate developed the power cell to be capable of high energy density, low temperature operation, and both high discharge and charge rates, allowing very short recharge times of depleted batteries which power cells today cannot achieve. Enevate’s power cell has been tested at up to 10C sustained discharge rates.
