ABSTRACT:
A thin film multi-layered electrolyte for a rechargeable electrochemical cell, and a rechargeable electrochemical cell including said electrolyte. The multi-layered electrolyte consists of a primary electrolyte material having at least one secondary electrolyte material disposed on one surface thereof. The secondary electrolyte material should be selected so as to have a potential stability window sufficient to prevent decomposition of the primary electrolyte, while preventing chemical reactions leading to the formation of ionically non-conducting materials on the surface of the electrodes of the electrochemical cell. A rechargeable electrochemical cell is made by disposing the multi-layered electrolyte material between a positive and negative electrode.
