A common method for measuring a battery’s performance involves cycling the battery between its empty and full states. During each cycle, the battery’s actual capacity is determined by calculating the total discharged capacity, while the coulombic efficiency (CE) is calculated by dividing the discharge capacity by the charge capacity.<\/p>\n\t\t
