PURPOSE: To manufacture an electrode easily in an industrial coating process using a specified coating paste for electrode and to establish an excellent battery performance. CONSTITUTION: A coating paste for electrode is used which is in the form of emulsion in water or in dispersion, and therewith it is practicable to prepare a consistent paste suitable for being applied without use of any solvent and manufacture an electrode easily with high safety in works. The yielded electrode exhibits a low wet swelling property for electrolytic solution and an excellent battery performance. The water dispersion contains 0.1-13wt.% propylene-fluorine copolymers (propylene-ethylene tetrafluoride copolymer and/or propylene-ethylene tetrafluoride-vinylidene fluoride copolymer), 0.2-2wt.% carboxymethyl cellulose. 0-1.0wt.% polyacrylic acids, and 98.5-85wt.% active material for battery. |
