METHOD FOR MANUFACTURING LITHIUM ION POLYMER BATTERY USING GEL POLYMER ELECTROLYTE, CAPABLE OF EASILY CONTROLLING THE PHYSICAL PROPERTIES OF GEL

摘要

PURPOSE: Provided is a method for manufacturing a lithium ion polymer battery using a gel polymer electrolyte which has high voltage, high energy and excellent cycle characteristic, and can easily control the physical properties of gel. CONSTITUTION: The method for manufacturing a lithium ion polymer battery comprises injecting an electrolytic liquid-containing precursor into an electrode laminate and then, polymerizing it by heat to obtain a gel-phase electrolyte. The electrode laminate includes a cathode layer(2) comprising an active material capable of lithium ion-intercalation and deintercalation which is deposited on a cathode collector(1); an anode layer(4) comprising an active material capable of lithium ion-intercalation and deintercalation which is deposited on an anode collector(5); and a separator(3) interposed between the cathode layer(2) and the anode layer(4).
