Cyanophosphines other than P(CN)react with lithium dicyanamide to produce lithiated carbon phosphonitrides with mobile Liions.

Lithium conducting carbon phosphonitrides from substituted cyanophosphine

Carbon phosphonitride (CPN) including tricyanophosphine (P(CN)), its pre-polymer (CPN-PP), and/or solid CPN(CNP) can serve as a useful additive for thermoset resins, resulting in improved thermal and mechanical properties.

Carbon phosphonitride polymer additives

A method of preparing borosulfate materials avoids the need for fuming sulfuric acid, also known as oleum. Instead, B(OH)present in solution in concentrated sulfuric acid at 5% to 15% by weight is reacted with a cation source at 100-250° C. under dynamic vacuum while in connection with a receiving vessel comprising a desiccant and separate from the reaction vessel, thereby causing formation of a borosulfate material in the reaction vessel while eliminated water is collected in the receiving vessel.

Scalable method for preparing crystalline borosulfate materials

Substituted cyanophosphine additives for lithium conducting carbon phosphonitrides

Described herein is the preparation of carbon phosphonitride pre-polymers that are soluble in organic solvents and can be further thermoset into carbon phosphonitride extended solids (i.e. films, monoliths, etc.) with an approximate empirical formula of CNP.

Organic solvent processable carbon phosphonitride pre-polymers

Borosulfate salts of protic Br&#xf8;nsted bases, for example NH[B(SO)], can serve as proton conductors in electrochemical devices such as fuel cells, flow batteries, and electrolyzers.

Borosulfate proton conducting materials

A lithiated carbon phosphonitride material is made by, for example, reacting P(CN)with LiN(CN)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&#xb0; C. and exhibits up to 10S&#xb7;cm2 of Liconductivity.

Lithiated carbon phosphonitride extended solids

P(CN)3 reactions with lithium dicynamide producing metalated carbon phosphonitride extended solids

A material with the empirical formula CNP is made by polymerizing P(CN)in a polar aprotic solvent such as acetonitrile, by heating, irradiation with ultraviolet light, and/or using a polymerization initiator and/or a catalyst.
