ELECTRODE-TERMINAL FILM WITH HEAT-RESISTING PROPERTY, METHOD OF MANUFACTURING THE SAME AND ELECTRODE TERMINAL COMPRISING THE SAME

摘要

PURPOSE: A high thermal resistant film for electrode terminal is provided to improve the durability of secondary batteries since heat adhesiveness and high temperature dimensional stability are secured at the same time and internal electrolytic property is excellent. CONSTITUTION: A high thermal resistant film for electrode terminal (100) comprises a polymer layer, which is interposed between the pouch and electrode terminal, as a main material (120) for sealing the pouch. The polymer layer is at least one selected from the group consisting of ethylene norbornene copolymer, polymethylene pentene, polycarbon terephthalate, and polyphenylene sulfide. The one selected from the group consisting of ethylene norbornene copolymer, polymethylene pentene, polycarbon terephthalate, and polyphenylene sulfide is mixed with a polypropylene resin at a weight ratio of 1:9-5:5.
