摘要： A plurality of positive electrode plates and negative electrode plates are stacked alternately upon one another with intervening separators therebetween, wherein 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. Collector plates are brought in tight contact with respective lateral edges of the positive and negative electrode plates, and heat is applied to the collector plate on an opposite surface of the electrode plates from a non-contact type heat source at several locations in lines along a direction in which the electrode plates are stacked.

摘要： Positive electrode plates and negative electrode plates are arranged alternately with intervening separators, and their end faces are respectively butted on collector plates. A solder material made from nickel alloy is disposed on the surfaces of the collector plates, which are made from nickel. An electron beam is irradiated onto the collector plates for causing the solder material to melt, thereby bonding the end faces of the positive and negative electrode plates with the collector plates.

摘要： Positive and negative electrode plates, after being dried, are layered alternately upon one another with intervening separators therebetween to constitute electrode plate groups. These electrode plate groups are transferred in succession from one to another of a plurality of preliminary chambers, which are respectively constructed to be able to create vacuum of various levels and arranged so that the vacuum level is gradually increased, and finally introduced into a processing chamber in which the vacuum level is highest, where the welding of collector plates to the electrode plate groups is performed with an electronic beam irradiating device. After that, the electrode plate groups are taken out through a post-processing chamber.

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.
