Abstract
Provided herein is a method of preparing carbon-graphene-lead composite particles, comprising the steps of forming a dispersion of lead particles, graphene particles and cellulose in an aqueous solution, spray drying the dispersion to aggregate the lead particles, graphene particles and cellulose to form cellulose-graphene-lead composite particles, and heating the cellulose-graphene-lead composite particles, to carbonize the cellulose to result in the formation of the carbon-graphene-lead composite particles.
