PURPOSE:To obtain a secondary battery with highly flexible, seat-like electrodes having excellent adhesiveness to metal sheets by utilizing powdery conductive high polymer. CONSTITUTION:A specified amount of conductive high polymer, conductive minute particles of an optional composition, steel balls, etc., are added to a binder solution and then dispersed. The dispersed liquid is applied on a conductive film, and then by drying it, a sheet-like electrode can be obtained. Conductive films include coating films on which metals such as iron and aluminum or alloys are evaporation-deposited or applied dud the film thickness should preferably be 5 to 50mum. Conductive high-polymers include polypillol and polythyophen, which are to be used conveniently as needed. The particle size of conductive high-polymer and conductive minute particles should preferably be from 0.1mu to 500mu. As a result, a secondary battery with highly flexible and highly reliable seat-like electrodes can be obtained. |
