Abstract
An electrode precursor sheet in which the active electrode material is bound by a polymer binder that includes an oxidized polymer or a blend of a first polymer with an oxidized polymer additive. The oxidized polymer advantageously has a minimum oxygen content of 1 atom % and may be an oxidized form of the first polymer.
