PURPOSE: A high molecular solid electrolyte is provided which has good mechanical strength, adhesive strength and interfacial property when being employed to a lithium secondary battery. And a lithium secondary battery containing thereof is also provided. CONSTITUTION: The high molecular solid electrolyte comprises: (i) a high molecular matrix which is a terpolymer of polyacrylonitrile, polyvinylidenechloride and polymethylmethacrylate; (ii) an ionic organic salt which is LiPF6 or lithium LiAsF6; and (iii) a solvent which is selected from the group consisting of ethylene carbonate, propylene carbonate, diethyl carbonate, dimethyl carbonate, ethyl methyl carbonate and Y-caprolactone. The lithium secondary battery consists of the cathode(3, 5) being composed of lithium cobalt oxide, the high molecular solid electrolyte(1) and the anode(7) being composed of lithium electrode or carbon electrode. |
