Tubular battery electrodes are filled with a mix of lead oxide, sulfuric acid and water to which electrolyte-resistant fibers have been added. These fibers strengthen the mass and reduce its tendency to escape through the pores of the tube envelope fabric. Also the product resulting from this method.

Storage battery electrode tubes and method of filling

Multi-cell battery cooling is accomplished by cooling elements immersed in the cell-top electrolyte. The elements have high heat conductivity and electric resistance. The cooling medium has low electric resistance. Various configurations of circulatory flow paths provide various utilizations for the medium beyond that of cooling the cells.

Battery cell cooling system

Pasted storage battery plates are dried by subjecting them to an alternating magnetic field which induces heating of the plate grids, thereby drying the paste from the inside.

Drying of storage battery plates

The vertical rods of the battery plate grid are formed partly of whole rods and partly of half rods. The steps at which transitions from whole to half rods take place are positioned to optimize current flow patterns.

Plate grid for lead storage batteries

A storage battery plate has lead bars positioned within channels defined by a grid of plastic strips. These channels also contain the active mass. The channels are closed off by electrolyte permeable cover layers.
