Title: High-conduction GE substituted LiAsS4 solid electrolyte

Abstract

A solid electrolyte for a lithium battery includes Li3+xGexAs1-xS4 where x=0 to 0.50. The value of x can be a range of any high value and any lower value from 0 to 0.50. For example, x can be 0.25 to 0.50, and x can be 0.3 to 0.4, among many other possible ranges. In one embodiment x=0.33 such that the solid electrolyte is Li3.334Ge0.334As0.666S4. A solid electrolyte for a lithium battery can include LiAsS4 wherein ½ to ⅔ of the As is substituted with Ge. A lithium battery and a method for making a lithium battery are also disclosed.
