Title:
POROUS CARBON-METAL/ALLOY COMPOSITE MATERIAL, SYNTHESIS METHOD, AND ELECTRODE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2017/221779
Kind Code:
A1
Abstract:
A porous carbon-metal/alloy composite material includes a composition represented by (1-a)Sn1-xM1
x + 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 porous carbon-metal/alloy composite material includes the steps of dissolving one or more metal salts and a metal salt of polysaccharide to form a mixture; subjecting the mixture to heat treatment under an inert atmosphere to form carbon-metal/alloy composite material and metal salt by-product; and washing the formed carbon-metal/alloy composite material and the metal salt by-product with washing solvent to remove the metal salt by-product and obtain the porous carbon-metal/alloy composite material.
