Abstract
A solid-state electrolyte capable of lithium ion transfer comprising and interdiffused combination of a lithium metal oxide and a metal halide.
Claims6
A solid-state electrolyte for use in electrochemical devices consisting essentially of an interdiffused mixture of lithium ion, oxygen, a halide and at least one element from the group of M' and M", said electrolyte having a composition calculated to result from the interdiffusion of a material "A", and material "B", said material "A" being representable by a formula LiM'O.sub.n and said material B being representable by a formula Li.sub.x M".sub.y X.sub.z wherein, in said formulas,
- X=is a halide atom,
- M' and M" represent at least one element from Groups IIA, IIIA, LLB, IVA, IVB, VA and VB of the Periodic Table,
- n=is a number depending on the valence of M' and calculated by
- n=(1+valence of M'/2)
- x=is 0 or a number up to 1,
- y=is a number from 0.1 to 1, and
- z=is a number depending in part on the valence of M" and calculated by z=x+y (valence of M").
