[PROBLEMS] To provide a lithium polymer secondary battery using a hybrid polymer electrolyte and a method for manufacturing the same. SOLUTION: A step of manufacturing a predetermined unit anode plate, a unit cathode plate and a separator containing a plasticizer, and a step of extracting and drying the plasticizer from the unit anode plate, the unit cathode plate and the separator, respectively. Forming a unit battery cell by laminating the unit anode plate and the unit cathode plate with a separator interposed between the unit anode plate and the unit cathode plate; and impregnating the plasticizer extraction site with an electrolyte. This is a method for producing a polymer secondary battery. As a result, the productivity of the lithium polymer secondary battery using the hybrid polymer electrolyte is improved, and the shape of the electrode current collector of the lithium polymer secondary battery has a foil shape as well as an expanded metal or a perforated metal shape. Current collectors may also be used. |
