Product Introduction:
The high-power supercapacitor module is a hybrid electrochemical energy storage device that combines the embedding mechanism of the lithium-ion battery anode and the double-layer mechanism of the double layer capacitor (EDLC) cathode. The combination of negative battery type LTO electrode and positive capacitor type activated carbon (AC) results in an energy density of approximately. 20Wh/kg, approximately 4-5 times the standard double layer capacitor (EDLC). However, the power density has been proven to match EDLC as it can fully discharge within a few seconds. On the negative electrode (anode) where activated carbon is frequently used, charges are stored in a double layer formed at the interface between the electrode and electrolyte. Like EDLC, the voltage of LIC varies linearly, which increases the complexity of integrating them into systems with power electronic devices that expect more stable battery voltage. Therefore, LICs have a high energy density that varies with the square of the voltage. The capacitance of the anode is several orders of magnitude larger than that of the cathode. Therefore, the change in anode potential during the charging and discharging process is much smaller than the change in cathode potential.
