Abstract
A battery includes an external terminal, a thermal fuse, a bare cell, an electrode assembly disposed within the bare cell and electrically coupled to the external terminal via the thermal fuse, such that the thermal fuse electrically disconnects the electrode assembly from the external terminal when a temperature of the battery reaches a predetermined value, a top cover, a protective circuit module within the top cover and on the bare cell, and a thermally insulating top sheet disposed on the thermal fuse, between the thermal fuse and the protective circuit module, the top sheet having a recess configured to receive the thermal fuse, such that the top sheet covers the top surface of the thermal fuse.
