Solid state electrochemical cell including lithium iodide as an electrolyte additive

摘要

An improved solid state electrochemical cell is provided including a lithium ion conducting solid electrolyte. The lithium ion conducting solid electrolyte is a solid solution of lithium germanium oxide and lithium vanadium oxide that includes lithium iodide as an additive. The improved cell can be used as a high temperature high rate rechargeable cell or as a high temperature thermal cell.
