FILM FOR ELECTRODE TERMINAL OF LITHIUM POLYMER SECONDARY BATTERY AND ELECTRODE TERMINAL COMPRISING THE SAME

摘要

PURPOSE: A film for an electrode terminal of a lithium polymer secondary battery is provided to suppress electrolyte from being leaked and to prevent shrink generated at a side of the electrode terminal. CONSTITUTION: A film(100) for an electrode terminal of a lithium polymer secondary battery comprises a non-polar polypropylene resin layer(110), and a polar polypropylene resin layer(120) contacting one side or both sides of the non-polar polypropylene resin layer. The polar polypropylene resin layer has a melting point of 120-150°C. The non-polar poly propylene resin has a melting point of 155-240°C.
