Abstract: A battery includes a battery cell matrix including a plurality of battery cells arranged in M rows and N columns. M and N are integers larger than or equal to 2. Each battery cell includes a casing, two end caps arranged along a column direction, and two electrode terminals arranged at the two end caps, respectively. In the column direction, electrode terminals of two adjacent battery cells are opposite and coupled to each other. The battery further includes a reinforcing plate extending in a row direction and fixed to the casings of the N columns of battery cells. A size of the reinforcing plate in the column direction is smaller than a size of the battery cells in the column direction. The reinforcing plate is fixed to the casings of the battery cells in two adjacent rows among the M rows.
