Abstract:
A method of manufacturing a lithium secondary battery comprising the steps of:mixing a polymer mixture including a) polyvinylidene fluoride-based polymer and b) at least one polymer selected from the group consisting of polyacrylonitrile and polymethyl methacrylate with a solvent in which a lithium salt is dissolved, said polymer mixture and said solvent being mixed in a mixing ratio of about 1:3-10; heating thus obtained first mixture to obtain a polymer electrolyte composition; coating thus obtained polymer electrolyte composition on a first electrode which is one of an anode and a cathode, and then drying to obtain a polymer electrolyte layer; and attaching a second electrode which is a remaining one of said anode and cathode onto said polymer electrolyte layer.
