Abstract
Provided by the present invention is a new anode material comprised of a carbon obtained by pyrolyzing a polymer of a conjugated vinyl monomer. The carbon is suitable for a lithium intercalated anode as it offers potential advantages of high capacity. The economics of manufacturing such anodes are also beneficial.
