摘要：
A secondary battery comprising a heat-sensitive indicator on the outer surface of the battery is disclosed. The color of the heat-sensitive indicator changes according to battery temperature. The heat-sensitive indicator may comprise a sheath. When the internal temperature of the battery increases rapidly, the heat-sensitive indicator changes color to alert the user that the battery is abnormally hot.
