ABSTRACT:
A rechargeable battery reducing internal resistance and equalizing the distribution of current flow in an electrode plate assembly. A plurality of battery jars are connected to one another through partition walls. A power generation element including an electrode plate assembly, in which a cathode plate and an anode plate are stacked together with a separator arranged in between, and collector plates joined to opposite ends of the electrode plate assembly are accommodated in each battery jar. The collector plates on opposite sides of the partition wall formed between two adjacent battery jars are connected to each other. Connection holes are formed in the partition wall at a plurality of locations. Connection projections, which project from the collector plates, are fitted into the connection holes and welded. The connection projections have distal ends that are in contact with each other.
