Abstract
The present disclosure relates to a device and method for controlling discharge by calculating a slope of a discharge profile of a battery having a lithium-based cathode material and a silicon-based anode cell material, counting a frequency the slope is equal to or smaller than a preset slope value and adjusting a final discharge voltage in response to the counted frequency being above a predetermined frequency.
