摘要： A prismatic sealed battery has a prismatic battery case (3) which includes a plurality of prismatic containers (4) coupled in a row via partitions (5), electrode plate assemblies (8), and collectors (10) which are joined to lead portions on both sides of the electrode plate assemblies (8). Each container (4) contains the electrode plate assembly (8) to which said collectors 10 are joined. An opening (21) is formed in at least one side wall (20) of the prismatic battery case (3) and in a position where each partition (5) is disposed, in such a manner as to face the containers (4) on both sides, and a conductive connection member (23) disposed in the opening (21) is connected to the collectors (10, 10) on both sides of the partition (5). Since the current-carrying path between the electrode plate assemblies (8) becomes short, internal resistance decreases, and hence internal resistance per cell (2) is reduced. Even and full use of the whole electrode plate assembly (8) achieves higher power output.
