Abstract
An improvement in the production of a cell electrode system comprises a process in which a fibrillatable polymer, an electrode active material and a removable, polymeric pore-former are subjected to conditions to convert the polymer by a dry process technique to fibrous form and to form a composition comprising discrete fibers through an intimate mixture consisting essentially of electrode active particles, and pore-former, said pore-former also serving as a processing agent and being present in a major amount, and then removing the pore-former from such composition.
