摘要： A rechargeable battery pack may include a battery cell configured to draw out an electrode tab from an electrode assembly accommodated in a pouch, a protection circuit module (PCM) connected to an electrode tab drawn out to a terrace of the pouch and connected to a printed circuit board (PCB) including a protection circuit through a flexible printed circuit board (FPCB). The rechargeable battery pack may include top tape configured to surround the protection circuit module and is attached to the battery cell to form a terrace space therein, and a flame retardant coated portion formed by coating a flame retardant coating agent on at least one portion of the protection circuit module exposed to an outside of the top tape.
