Abstract

A lithiated carbon phosphonitride material is made by, for example, reacting P(CN) 3 with LiN(CN) 2 in solution (for example, dimethoxyethane or pyridine), then drying the solution to obtain the product. The material is a thermoset that is stable to over 400° C. and exhibits up to 10 −3 S·cm2 of Li + conductivity.

Claims (3)

1. A material comprising a polymer of lithiated carbon phosphonitride and consisting essentially of Li, C, P, and N.

2. The material of claim 1 , having a conductivity of 10 −3 S cm −1 at 90° C.

3. The material of claim 1 , in a condition of having been made by reacting P(CN) 3 with LiN(CN) 2 in solution, then drying the solution to obtain the material.
