APPARATUS FOR PRODUCING LITHIUM POLYMER BATTERY USING CONTINUOUS ROLL-TO-ROLL SYSTEM BY DIRECT SOLUTION CASTING TECHNOLOGY AND METHOD FOR PRODUCING LITHIUM POLYMER BATTERY USING THE SAME

摘要

PURPOSE: A manufacturing apparatus and a manufacturing method of a lithium polymer battery are provided to increase process efficiency through a roll-to-roll continuous process, and to improve electrolyte activity in an interface. CONSTITUTION: A manufacturing apparatus(200) of a lithium polymer battery comprises: an anode slot die(210) coating cathode active material slurry on a cathode current collector; a first drier(230) forming a cathode active material layer on the cathode current collector by drying the coated cathode active material slurry; a solid polymer electrolyte slot die(220) coating solid polymer electrolyte slurry on the cathode active material layer; and a second drier(240) forming a solid polymer electrolyte layer on the cathode active material layer by drying the coated solid polymer electrolyte slurry. On cathode electrolyte, the cathode active material layer and the solid polymer electrolyte layer are sequentially and continuously formed.
