METHOD FOR MANUFACTURING ELECTRODE FOR SECONDARY BATTERY OF NONAQUEOUS ELECTROLYTE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrode for secondary battery of nonaqueous electrolyte, which has no such problems as shrinking or swelling of active materials for a cathode and an anode when charging or discharging, followed by increase for contact resistance between an active material and a metal collector while reducing cyclic characteristics in charging and discharging. SOLUTION: For the electrode for secondary battery of nonaqueous electrolyte, the process of manufacturing it is designed in such ways that the temperature of thermal treatment with the electrode should be higher than the melting point of binders and the treatment should be done at higher temperature than softening temperature for the metal collector of electrode, and this thermal treatment should be done before the process of rolling.
