Abstract
An electrode composite conducting agent for a lithium battery includes a carbonaceous conductive material, and the graphene-silica composite, wherein the graphene-silica composite includes a matrix including graphene, and a silicon suboxide of the formula SiOx wherein 0<x<2, or a combination of silicon dioxide and silicon suboxide of the formula SiOx wherein 0<x<2, or a combination thereof, wherein an amount of the graphene-silica composite is 20 parts by weight or less, based on 100 parts by weight of a total weight of the composite conducting agent. Also an electrode for a lithium battery including the electrode composite conducting agent, a method of manufacturing the electrode, and a lithium battery including the electrode.
