METHOD FOR PREPARING LITHIUM SECONDARY BATTERY

摘要

PURPOSE: A method for preparing lithium secondary battery is provided to improve processability of a gel polymer electrolyte and battery assembly. CONSTITUTION: The method comprises a) coating a polymer film with affinity for electrolyte on at least one side of the anode and cathode; b) placing a porous separator between the anode and cathode; and c) integrating the electrode and the porous separator by gelling the coated polymer film with affinity for the electrolyte with liquid electrolyte at high temperature.
