NOVELTY - NOVELTY -The pressure-sensitive adhesive tape (3) comprises a substrate and a pressure-sensitive adhesive layer provided on a surface of the substrate. The pressure-sensitive adhesive layer has a thickness of 2-100 mu m. The pressure-sensitive adhesive tape has a 180 degrees peeling adhesive force towards an aluminum foil after a pressure bonding of greater than or equal to 0.05 N/10 mm at 25 degrees C and a 180 degrees peeling adhesive force towards an aluminum foil after thermo compression bonding, at a temperature of 30-200 degrees C, of greater than or equal to 0.5 N/10 mm. The pressure-sensitive adhesive layer contains a thermoplastic elastomer.    USE - The pressure-sensitive adhesive tape is useful for manufacturing a battery (claimed) such as a lithium ion battery.    ADVANTAGE - The reusable pressure sensitive adhesive tape can be easily and economically manufactured and reattached with high adhesiveness and workability and increased scrappage rate, prevents short circuit thus enhancing lifespan and capacity of the battery.    DETAILED DESCRIPTION - The pressure-sensitive adhesive tape (3) comprises a substrate and a pressure-sensitive adhesive layer provided on a surface of the substrate. The pressure-sensitive adhesive layer has a thickness of 2-100 mu m. The pressure-sensitive adhesive tape has a 180 degrees peeling adhesive force towards an aluminum foil after a pressure bonding of greater than or equal to 0.05 N/10 mm at 25 degrees C and a 180 degrees peeling adhesive force towards an aluminum foil after thermo compression bonding, at a temperature of 30-200 degrees C, of greater than or equal to 0.5 N/10 mm. The pressure-sensitive adhesive layer contains: a thermoplastic elastomer that is an acid-modified thermoplastic elastomer; and a tackifier (5-50 pts.wt.%). INDEPENDENT CLAIMS are included for:    (1) a battery; and    (2) a process for manufacturing a battery.
