BATTERY STRUCTURE

A battery structure includes battery cells arranged in a first direction and in which each battery cell includes an electrode terminal, a busbar holder on a top of the battery cells and including a through hole, a busbar including a first flat surface and a second flat surface each electrically connected to one of the battery cells, fixing members coupled to the busbar holder in which each fixing member is fixed between the first and second flat surfaces of the busbar, and separating members coupled to the busbar holder and separating the busbars.
