Abstract
A battery pack includes a battery cell including a cell tab, a protective circuit board including an internal terminal coupled to the cell tab and a positive temperature coefficient (PTC) device connected to the internal terminal, and a heat transfer member contacting the cell tab. The heat transfer member may be attached to the cell tab as well as the PTC device. Heat generated in the battery cell, the cell tab, and the internal terminal is quickly transferred to the PTC device through the heat transfer member to quickly interrupt current flow when the battery cell is exposed to high temperature. Therefore, the battery pack may have the improved stability and reliability.
