ABSTRACT:
A storage battery and a method of making same wherein the positive plates of one cell are electrically connected to the negative plates of an adjacent cell without the need of welding. A conventional battery case is utilized and modified to provide an opening through the partitions between the cells. A conductive material, either lead particles or a low-melt alloy in molten form, is added in the cells and through the openings therebetween. The lugs of the positive plates of the cell are all positioned downward in the cell and are aligned with all the lugs of the negative plates in an adjacent cell. The conductive material electrically connects all the positive lugs of the one cell to the negative lugs of the adjacent cell. Where particulate material is utilized as the conductive material, a sealing agent, for example, epoxy resin, is poured onto the conductive material to render the material impermeable and to seal it in place. If desired, the conductive material can be sintered or even melted after addition to the battery case by applying external heat through the battery case.
