Although the LIBSC has a high power density and energy density, different positive and negative electrode materials have different energy storage mechanism, the battery-type materials will generally cause ion transport kinetics delay, resulting in severe attenuation of energy density at high power density [83], [84], [85]. Therefore, when AC is used as a cathode
By using an external power source, electrons are moved from a positive electrode to a negative electrode during charging. As the electrolyte bulk flows to the electrodes, the ions are released. Electricity moves from one negative electrode to the other positive electrode when it discharges, and ions migrate from surface to bulk electrolyte as well.

As a result, on the positive electrode, there is an accumulation of negative charges which is attracts by positive charges due to Coulomb’s force around the electrode and electrolyte. Electrolyte–electrode charge balancing results in the formation of an EDL.
Different from negative electrode, the SEI on positive electrode is mainly composed of organic species (e.g., polymer/polycarbonate).32 In brief, the stable SEI on electrodes has significant influence on the safety, power capability, shelf life, and cycle life of the battery.
Electrochemical energy storage devices based on solid electrolytes are currently under the spotlight as the solution to the safety issue. Solid electrolyte makes the battery safer and reduces the formation of the SEI, but low ion conductivity and poor interface contact limit their application.
