PACKED BATTERIES AND METHOD OF MAKING THE SAME

摘要

A packed battery includes a frame composed of a pair of substantially I-shaped frame members (1, 2) molded of synthetic resin and joined together to hold therein a power generating elements composed of a plurality of series-connected cells (5, 6), and an end cap (3) molded of synthetic resin and joined with the frame to close an open end of the frame. One of the frame members (1) has in its one end face a pair of apertures through which a pair of external terminals (8) is inserted for connection to positive and negative terminal end faces of the power generating element. With this construction, the packed battery has a high capacity per unit volume and the external terminals (8) and the positive and negative terminal end faces can be welded easily and efficiently. Accordingly, the packed battery can be manufactured at a high rate of production.
