ELECTROCHEMICAL CELL WITH SOLID AND LIQUID ELECTROLYTES

摘要

A hybrid solid state battery may comprise: a metal ion negative half-cell; a metal ion conducting solid state electrolyte separator; and a positive half-cell comprising an electrolyte selected from the group consisting of a liquid electrolyte, a gel electrolyte and a polymer electrolyte; wherein the solid state electrolyte separator is between the metal ion negative half-cell and the electrolyte in the positive half-cell. The solid state battery may be a Li-ion battery, with a Li-ion conducting solid state electrolyte separator, such as one or more of LiPON, Li7La3Zr2O12, doped anti-perovskite compositions, Li2S—P2S5, Li10GeP2S12, and Li3PS4, for example. A method of fabricating a Li-ion cell may comprise combining a lithium metal electrode, a solid state electrolyte separator and a positive half-cell, wherein the positive half-cell comprises a liquid/get/polymer electrolyte and wherein the solid state electrolyte is between the lithium metal electrode and the liquid/gel/polymer electrolyte in the positive half-cell.
