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 lithiated carbon phosphonitride material in a state of having been made by reacting LiN(CN) 2 with (diphenylamino)dicyanophosphine.

2. The material of claim 1 , wherein the reacting process is made in γ-valerolactone.

3. The material of claim 2 , wherein the (diphenylamino)dicyanophosphine was used at 40.9 mg in 0.5 g stock solution.

4. The material of claim 2 , wherein the (diphenylamino)dicyanophosphine was used at 61.3 mg in 0.5 g stock solution.

5. The material of claim 2 , wherein the (diphenylamino)dicyanophosphine was used at 122.6 mg in 0.5 g stock solution.

6. A lithiated carbon phosphonitride material in a state of having been made by reacting LiN(CN) 2 with a cyanophosphine other than P(CN) 3 .
