BATTERY MODULE

Abstract:

To provide a battery module capable of improving the workability in manufacturing. A battery module (1) includes: a plurality of battery cells (10) each including: a battery (11); and an exterior packaging body (12) that houses the battery (11). The battery (11) incudes: a negative electrode including a negative electrode current collector; an electrolyte; and a positive electrode including a positive electrode current collector. The plurality of battery cells (10) each include: a current collector tab (13, 15) extending from each of the positive electrode current collector and the negative electrode current collector; and a current collector tab lead (14, 16) connected to each of the current collector tabs (13, 15). The current collector tab lead (14, 16) extends in a vertical direction (y2) perpendicular to the stacking direction (y1) of the plurality of battery cells (10).
