Abstract
A new class of metal hydride alloy and processes for forming these alloys is disclosed. The alloys are comprised essentially of organically soluble metal hydrides and single molecular layer type transition metal dichalcogenides. They are produced via a non-metallurgical route in organic solvents under mild conditions. These alloys have exhibited improved qualities in battery applications.

A method for producing a metal hydride alloy of the form MX.sub.2 Y wherein MX.sub.2 is comprised of single molecular layer transition metal dichalcogenide, X is a chalcogen, and Y is an organic-solvent soluble metal hydride, said method comprising the steps of:
- (a) providing a solution comprised of a soluble metal hydride and an organic solvent wherein said metal hydride is Protically reactive and immiscible in water and
- (b) providing a suspension consisting essentially of single molecular layer transition metal dichalcogenide particles homogeneously dispersed in an aprotic solvent and
- (c) combining the solution with the suspension and
- (d) recovering the precipitate, which is comprised of the soluble metal hydride/transition metal dichalcogenide alloy wherein said metal hydride has not reacted to form a metal hydroxide.

- (a) providing a solution comprised of a soluble metal hydride and an organic solvent wherein said metal hydride is protically reactive and immiscible in water,
- (b) providing a suspension comprised of single molecular layer transition metal dichalcogenide particles homogeneously dispersed in a protic solvent,
- (c) replacing said protic solvent with an aprotic solvent,
- (d) after said replacing, combining the solution with the suspension,
- (e) recovering the precipitate, which is comprised of the soluble metal hydride/transition metal dichalcogenide alloy wherein said metal hydride has not reacted to form a metal hydroxide.
