METHOD FOR PREPARING LITHIUM SECONDARY BATTERY

摘要

PURPOSE: A method for preparing lithium secondary battery is provided to improve processability of a polymer electrolyte and battery assembly without preprocessing and a gelling process at high temperature. CONSTITUTION: The method comprises a) preparing an electrode, a porous separator, and a polymer film with affinity for electrolyte; b) placing the polymer film with affinity for an electrolyte between the electrode and the porous separator; and c) integrating the electrode and the porous separator by gelling the polymer film with affinity for the electrolyte with liquid electrolyte.
