摘要： Disclosed is a method of manufacturing a lithium secondary battery. 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 is mixed with a solvent in which a lithium salt is dissolved. The mixing ratio of the polymer mixture and the solvent is about 1:3-10. Thus obtained first mixture is heated to obtain a polymer electrolyte composition. And this polymer electrolyte composition is coated onto a first electrode which is one of an anode and a cathode, and then dried to obtain a polymer electrolyte layer. Then, a second electrode which is a remaining one of the anode and cathode is attached onto the polymer electrolyte layer. The polymer electrolyte has a good mechanical strength and the lithium secondary battery has a stable charge/discharge characteristic.
