Lithium ion supercapacitor module

Product introduction:

         Lithium ion supercapacitor module is a hybrid electrochemical energy storage device, which combines the embedding mechanism of lithium ion battery anode and the double-layer mechanism of 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 about. 20Wh/kg, about 4-5 times of the standard double-layer capacitor (EDLC). However, the power density has been proved to match the EDLC because it can discharge completely in a few seconds. On the negative electrode (anode) where activated carbon is often used, the charge is stored in the double electric layer formed at the interface between the electrode and the electrolyte. Like EDLC, the voltage of LIC varies linearly, which increases the complexity of integrating them into the system, which has power electronic devices that expect more stable battery voltage. Therefore, LICs have a high energy density, which 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 of anode potential during charging and discharging is far less than that of cathode potential.
