Abstract
Approaches are described for producing porous, polymer electrodes with good characteristics for incorporation into polymer batteries. Two preferred processes are presented. The polymer electrodes can be subjected to additional processing to increase their porosity and electrical conductivity. The polymer electrodes preferably are incorporated into a polymer battery where the components are laminated together.
