Abstract: A coated electrode includes a negative electrode and a carbon coating adhered to a surface of the negative electrode. The negative electrode includes an active material selected from the group consisting of lithium, silicon, silicon oxide, a silicon alloy, graphite, germanium, tin, antimony, or a metal oxide; a conductive filler; and a polymer binder. The carbon coating includes a percentage of a ratio of sp2 carbon:sp3 carbon ranging from 100% (100:0) to 0% (0:100).
