<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape for a non-aqueous battery that improves an insertion competence of an electrode in a battery case and can prevent a short-circuit between electrodes caused by a burr existing on an electrode plate by using the tape in the battery in which a non-aqueous electrolytic solution is to be sealed without causing a decrease in power of the battery. <P>SOLUTION: The pressure-sensitive adhesive tape for a non-aqueous battery has a pressure-sensitive adhesive layer on at least one side of a substrate, in which the pressure-sensitive adhesive layer contains ≥90 wt.% of a polyisobutylene rubber, and in which a content of a polyisobutylene rubber having a molecular weight of 800,000-2,200,000 is 15-50 wt.% based on the entire pressure-sensitive adhesive layer, a content of a polyisobutylene rubber having a molecular weight of 10,000-700,000 is 35-70 wt.% based on the entire pressure-sensitive adhesive layer, and a content of a component having a molecular weight of ≤10,000 is ≤5 wt.% based on the entire pressure-sensitive adhesive layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
