METHOD OF MANUFACTURING ELECTRODE PLATE FOR NON-AQUEOUS ELECTROLYTIC LIQUID SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTIC LIQUID SECONDARY BATTERY USING ELECTRODE PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode plate superior in adhesion with an active material mixture and conductivity, and a non-aqueous electrolytic liquid secondary battery superior in cycle life characteristics using the electrode plate.

SOLUTION: The method of manufacturing the electrode plate for a non-aqueous electrolytic liquid secondary battery is characterized in that an active material mixture paste containing a dispersant and a binder is coated on a current collector, and after drying and removing the dispersant, pressurized, and subsequently, heat-treated under the temperature of crystallization temperature or more and less than the melting point of the binder. The method of manufacturing the electrode plate for non-aqueous electrolytic liquid secondary battery is configured such that the active material mixture contains a lithium complex oxide which can store and release lithium ions or contains a carbon material which can absorb and release lithium ions. The non-aqueous electrolytic liquid secondary battery uses the electrode plate manufactured by the above manufacturing method at least for one of the positive electrode or negative electrode.
