  • Battery and grid for positive electrode for lead storage batteries
    Patent number: 4107407
    Abstract: An improved grid for the production of positive electrodes for use in electric storage batteries is disclosed. The grid is formed of a base of lead or a lead alloy which is essentially antimony-free and the base is coated with a lead alloy containing one or more metals whereby the resulting grid achieves charging potentials essentially the same as achieved with conventional lead-antimony alloy grids while minimizing the possibilities of antimony poisoning. The grid may be made by electrically coating the surface alloy onto the support.
