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.
Claims10
A grid for a positive electrode for electrical storage battery also including a negative electrode comprising a base of lead or a lead alloy which is essentially free from antimony coated on at least all surfaces which contact active material in the finished electrode with an alloy of lead and from 3 to 95 percent antimony, the amount of antimony being 2 percent or less by weight of the active material utilized in the finished electrode whereby the resulting grid achieves charging potentials of the same magnitude as those achieved with grids formed of lead alloys containing 6 to 12 weight percent antimony while minimizing the possibility of antimony poisoning of a negative electrode.
