  • Process of producing grids for a battery
    Patent number: 4443918
    Abstract: This invention relates to a process of producing plate grids for a lead acid storage battery. The process of the invention comprises the step of striking hard particles against surfaces of grid material to form roughness on the surfaces of the plate grids. The hard particles may be struck against surfaces of a lead alloy strip which the plate grids are to be made of by expanding or punching. They may be struck against surfaces of a mesh-like lead alloy strip which is formed by expanding or punching a lead alloy strip. Otherwise, they may be struck against the surfaces of a lead alloy strip and then against the surfaces of the mesh-like lead alloy strip which is formed by expanding or punching the roughened lead alloy strip.
