Abstract: A battery pack is disclosed. In one aspect, the battery pack includes a plurality of battery cells electrically connected to each other and comprising first and second outermost battery cells positioned at opposite ends thereof and a case accommodating the battery cells. The battery pack also includes a barrier wall formed between the battery cells and the case and a traversing tab positioned between the case and the barrier wall and electrically connecting the first and second outermost battery cells. At least one embodiment can facilitate a welding process while preventing a conductive tab connecting battery cells to a protective circuit module from being short-circuited.
