Abstract
The present disclosure provides a rechargeable electrochemical cell including an electrolyte side, a cathode side, and a polymer/plasticizer. The electrolyte side includes a solid glass electrolyte including an electrolyte mobile cation and electric dipoles, as well as an anode including a metal of the electrolyte mobile cation and contacting the solid glass electrolyte at an anode:solid glass electrolyte interface. The cathode side includes a cathode including a cathode active material into which a cathode guest cation is reversibly extracted/inserted. The cathode active material has a voltage versus lithium (Li) metal of between 3V and 15V. The polymer/plasticizer contacts the solid glass electrolyte at a solid glass electrolyte:polymer/plasticizer interface and the cathode at a polymer/plasticizer:cathode interface such that the cathode guest cation is confined to the cathode side and the electrolyte mobile cation is confined to the anode side during charge and discharge of the electrochemical cell.
