Abstract
A series of solid-state lithium ion composite electrolytes is described. The composite materials have lithium ions in an anionic framework wherein the anionic framework has lithium ion vacancies or interstitial Li+ sites. The anionic framework lattice is isostructural to a Laves Mg2Cu lattice and the lithium ion (Li+) conductivity of the solid state lithium ion electrolyte is at least 10−4 S/cm. The activation energy for lithium ion migration in the solid state lithium ion electrolyte is 0.36 sV or less. Composites of specific formulae are provided.
