  • Grid for Lead-Acid Battery with Electroconductive Polymer Coating
    Publication number: 20090269658
    Abstract: The present invention provides a method for manufacture of a grid structure for use in lead acid batteries using a substrate having low density and low melting point, the method comprising coating the substrate material with a first metal layer and a subsequent metal layer of lead/lead alloy and electrodepositing an electroconductive polymer to form a protective layer thereon.

  • Rapid coating process and its application to lead-acid batteries
    Patent number: 6889410
    Abstract: A precursor chemical compound is applied to a surface sought to be coated, and subjected to a rapid thermally activated chemical reaction process (RTACRP) in which the temperature is quickly raised and lowered. The desired coating is formed from the precursor chemical compound by a chemical reaction at the elevated temperature. The structural/chemical integrity of the surface is preserved due to the use of RTACRP. The approach may be used to manufacture a high-energy density lead-acid battery.
