METHOD FOR MANUFACTURING A SECONDARY LITHIUM ION BATTERY USING A POLYMER ELECTROLYTE

摘要

PURPOSE: A method for manufacturing a secondary lithium ion battery using a polymer electrolyte is provided to easily regulate the capacity of the battery by regulating the length, the width, and the number of windings. Further, the shape of the battery can be easily changed. CONSTITUTION: A circular secondary lithium ion battery is manufactured by winding four plates. The four plates comprises a cathode plate(1), a composite film(3), an anode plate(4), and a composite film(6). The cathode plate(1) is formed by coating carbon or black lead on both surface of a copper foil(2). The anode plate(4) is formed by coating lithium metal oxide on both surfaces of an aluminum foil.
