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. |
