Battery and method of manufacturing the same

Abstract

Abstract A storage battery case of synthetic resin in prepared which has a plurality of partition walls for forming cells therein, each wall having a notch formed its upper end portion, Into each notch is inserted a connector member so that opposite sides may face the respective cell. Then mold elements are brought into a position near the connector member to form an enclosed space around the peripheral portion of the connector member. Synthetic resin is then injected into the space of form a seal member so that at least a portion of the sides of the connector member facing the cell may be exposed. Then into each cell is inserted an electrode plate assembly, which has an electrode rod extending upward from an end thereof up to the connector member. In the next step, the upper ends of both electrode rods of the adjacent assemblies are connected to the connector member by means of electrical welding, for example. A battery case cover also made of synthetic resin is thermally bonded on the battery case so that each cell is isolated from each other. As a result a good liquid-tight effect of the connector extending through the partition wall in the battery is attainable with ease.
