Abstract
Powder of a polymer active material exhibiting an electro-chemical oxidation-reduction reaction is mixed with powder of a conductivity assisting agent to obtain a mixture. The mixture is molded by a thermal press into a unitary block. Thus, a cell electrode having a large film thickness is produced without causing cracks or breakage. The electrode having a large film thickness improves the energy density of the polymer secondary cell.
