ABSTRACT:
A structure for clamping a plurality of battery cells to prevent deformation thereof, includes a pair of pressure plates positioned against the ends of a stack of battery cells and a plurality of bands which extend around the cells and the end plates to hold the end plates in fixed position with respect to each other. The structure can be used with a plurality of sealed cells of rectangular configuration to pevent expansion of the cells of the type where pressure can build up therein, such as ni-clad rechargeable batteries, and thereby prevent bulging of the electrodes of the cells to injure the same. The pressure plates can be made of steel to also serve as heat sinks during welding of the bands, and the bands can be formed of steel strips which are preferably cinched tight about the cells and welded together. Partitions can be positioned between adjacent cells, with edges welded to the bands to prevent expansion of the cellsin a direction parallel to the pressure plates.
