摘要： The present disclosure provides an electrochemical cell including a solid glass electrolyte including an alkali metal working ion that is conducted by the electrolyte, and a dipole, an anode having an effective anode chemical potential μA, and a cathode having an effective cathode chemical potential μC. One or both of the cathode and anode substantially lack the working ion prior to an initial charge or discharge of the electrochemical cell. At open-circuit prior to an initial charge or discharge, an electric double-layer capacitor is formed at one or both of an interface between the solid glass electrolyte and the anode and an interface between the solid glass electrolyte and the cathode due to a difference between μA and μC.
