摘要

An electrode plate for a lead-acid storage battery which is composed of three thin grid units, each having its own active material. The characteristics of the cell can be controlled by varying the electrochemical properties of the different grid units. The lead alloy material of one grid unit may be different from the lead alloy material of another unit which can allow the use of some grids that are essentially free of antimony. The porosity of the active material on different grids can also be varied. The several grid units are joined together to provide a common electrical flag terminal which can be joined in a conventional manner to a pole bridge and thus be part of a plate set.
