Abstract
A group of electrodes are accommodated in a prismatic cell case of a rechargeable battery. Intervening separators are provided between positive and negative electrode plates arranged alternately in parallel to long lateral walls of the cell case. The positive electrode plates each include a lead portion having a surface on which at least one lead plate is attached. Lateral edges of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edges of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side. The protruding portions form the lead portions. Upper open ends of the cell cases are closed by an integral lid member.
