  • Current Collector Structure and Methods to Improve the Performance of a Lead-Acid Battery
    Publication number: 20060292448
    Abstract: A current collector of a battery includes a reticulated substrate having a circuitous network of pores and a metal applied to at least a portion of the reticulated substrate. The reticulated substrate may be a non-metal foam substrate, such as, for example, a carbon foam substrate, a reticulated vitreous carbon substrate or a graphite foam substrate.

  • Hydrogen evolution inhibiting additives for zinc electrowinning
    Publication number: 20050011769
    Abstract: A cetylpyridinium salt, cetylpyridinium chloride (CPC) is used as a hydrogen evolution inhibitor (a current efficiency improver) in a commercial zinc electrowinning process. Zinc electrowinning compositions containing a) antimony and b) antimony and glue were tested. Adding CPC at a 0.05 mM concentration to the electrowinning liquor resulted in increased current efficiency for both electrolytes.
