PURPOSE: Provided are a process for producing a polymer electrolyte having improved mechanical properties and a process for producing a lithium polymer secondary battery having stable charge/discharge property by using the polymer electrolyte. CONSTITUTION: The process for producing the polymer electrolyte(4) comprises the steps of: mixing a polyvinylidene fluoride polymer and an electrolyte not containing electrolyte salts in the weight ratio of 1:2-10, wherein the electrolyte is at least one selected from the group consisting of ethylene carbonate, propylene carbonate, diethyl carbonate, dimethyl carbonate, ethyl methyl carbonate, and gamma-butyrolactone; stirring and heating the mixture to prepare a homogeneous electrolyte slurry; and solidifying the electrolyte slurry. And the lithium polymer secondary battery is produced by laminating a cathode(6), the polymer electrolyte(4), and an anode(1). |
