MANUFACTURING METHOD OF CATHODE PLATE FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY USING THE CATHODE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of cathode plate for lithium secondary battery of which innermost part of an electrode plate group having a small radius of curvature is not cut, excellent in productivity and battery characteristics.

SOLUTION: On the manufacturing method of the cathode plate for a lithium secondary battery, heat treatment is applied at a temperature of 200 to 400°C by using a binder composed of a binder A decreasing its adhering property at 200 to 400°C and a binder B keeping its adhesive property at 200 to 400°C.
