PROBLEM TO BE SOLVED: To provide a composition for forming an electrode active material of a lithium secondary battery, a composition for forming a separator, and the manufacturing method of a lithium secondary battery using this composition. SOLUTION: This manufacturing method contains a step for forming a cathode and an anode by coating of a composition for forming an electrode active material containing an electrode active material, a binder, and a solvent on an electrode current collector; a step for forming a separator on both sides of the anode by using a composition for forming a separator containing polymer resin, a plasticizer, a filler, and a solvent; a step for forming a battery structure by placing the cathode on the separator and bonding them; a step for drying the battery structure under vacuum; a step for impregnating an electrolyte in the resulting product, and the plasticizer in the composition for forming the separator is at least one selected from the group comprising an ethylene glycol derivative, a cyclic carbonate base material, a non-cyclic carbonate base material, and a propylene glycol derivative. |
