A heat sensitive jacket label for battery and battery with the same

摘要

A heat sensitive jacket label (10a) for a battery comprises a base (1) made of a heat-shrinking film, a metal layer (2) provided on a back surface of the base, a heat-resistant insulating layer (6) provided on the metal layer, and a heat sensitive adhesive layer (3) on the insulating layer. The base (1) heat-shrinks at a temperature at least 15 DEG C higher than a temperature for effecting adhesion of the heat sensitive adhesive layer (3) to a body (16) of the battery, so as to prevent wrinkling of the jacket label (10a). The heat-resistant insulating layer (6) prevents the metal layer (2) from gradually dissolving into the adhesive layer (3) during storage of the battery in high-temperature or high-humidity conditions. Thus the metal layer (2) is able to continue to give the battery an attractive metallic gloss appearance.
