<p>Provided is a highly reliable storage battery module wherein internal shorts do not readily occur during use. This storage battery module (50) has a plurality of cylindrical storage batteries (10A, 10B) connected in series via a connection member (30). A winding electrode body (14) has a first collector welded to either a positive electrode plate or a negative electrode plate, at one end of the winding axis, and a second collector (20) welded to the other of either the positive electrode plate or the negative electrode plate, at the other end of the winding axis. The first collector is electrically connected to a sealing body. The second collector (20) has a planar shape having a slit formed in the periphery thereof, and has a center section welded to the inside surface of the floor section of a cylindrical exterior canister (22). The connection member (30) has one surface thereof welded to the outside surface of the floor section of the cylindrical storage battery (10B), at a position that does not overlap with the position of the second collector (20) slit. The other surface of the connection member (30) is welded to the sealing body in the other cylindrical storage battery (10A).</p> |
