Carbon-metal/alloy composite material, synthesis method, and electrode including same

Abstract

A carbon-metal/alloy composite material includes a composition represented by (1-a)Sn1-xM1x+aM2+cC, wherein: M1 includes one or more transition metals, metals, or metalloids; M2 includes one or more transition metals, metals, or metalloids; x is 0≦x≦1; a is 0≦a≦1; and c is 0<c≦99. A method of forming the carbon-metal/alloy composite material includes the steps of dissolving one or more precursor materials in a solvent to form a solution; adding an organic carbon forming precursor to the solution to form a mixture; heating the mixture in an autoclave reactor for a prescribed period of time; separating solids formed from the mixture after the heating; washing the separated solids with a washing solvent; and heating the washed solids under a non-oxidizing atmosphere to form the carbon-metal/alloy composite material.
