Fast charging and discharging
WebThe charge time of a supercapacitor is 1–10 seconds. The charge characteristic is similar to an electrochemical battery and the charge current is, to a large extent, limited by the charger’s current handling capability. The initial charge can be made very fast, and the topping charge will take extra time. WebApr 10, 2024 · The discharge rate is a crucial indicator for power batteries. The large rate discharge of the battery is a test for cathode and anode materials and electrolytes. For lithium iron phosphate cathode material, its structure is stable, the strain in charge and discharge processes are small, and it has the basic conditions for high-current discharge.
