| abstract | The present invention casts a cathode active material slurry composition comprising 80 to 95% by weight of a lithium composite oxide, 5 to 15% by weight of a binder, and 4 to 10% by weight of a conductive agent on a current collector and then dried to form a nonporous cathode electrode plate. Preparing a; (b) An anode active material slurry composition comprising 80 to 95% by weight of lithium metal or carbon, 5 to 15% by weight of binder and 4 to 10% by weight of conductive agent is cast on a current collector and then dried to form a nonporous anode Manufacturing the electrode plate; (c) preparing a film from a polymer matrix-forming composition comprising a polymer resin and a plasticizer, and then extracting the plasticizer to prepare a porous polymer matrix; And (d) sequentially stacking the non-porous cathode electrode plate, the porous polymer matrix, and the non-porous anode electrode plate, and then impregnating the organic electrolyte solution containing a non-aqueous organic solvent and a lithium salt. According to the present invention, according to the present invention, the capacity of the battery can be increased by adding an active material as much as the amount of plasticizer added, instead of adding a plasticizer during the production of the electrode plate, and the process of removing the plasticizer from the electrode plate can be omitted. And it is useful in that the manufacturing cost reduction effect can be obtained. |
