Abstract

Cyanophosphines other than P(CN) 3 react with lithium dicyanamide to produce lithiated carbon phosphonitrides with mobile Li + ions.

First claim

What is claimed is:

1. A method of preparing lithiated carbon phosphonitride material, the method comprising reacting LiN(CN) 2 with (diphenylamino)dicyanophosphine.

2. A method of preparing lithiated carbon phosphonitride material, the method comprising reacting LiN(CN) 2 with (diphenylamino)dicyanophosphine in γ-valerolactone.
