摘要： Disclosed are a polymer electrolyte composition, a method for preparing the same and a lithium secondary battery employing the same. The polymer electrolyte composition comprises a polymer mixture and a solvent in which a lithium salt is disclosed. The polymer mixture includes polyvinylidene fluoride-based polymer and at least one polymer selected from the group consisting of polyacrylonitrile and polymethyl methacrylate. Polyvinylidene fluoride-based polymer which has a good mechanical strength, polymethyl methacrylate polymer which has a good affinity and polyacrylonitrile polymer which has a good adhesiveness to electrodes are utilized. As a result, the mechanical strength and the adhesiveness to the electrodes of the polymer electrolyte can be improved to obtain a lithium secondary battery which has a stable charge/discharge characteristic and a high capacity.

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.
