  • Publication number: 20190319313
    Abstract: A battery enclosure including a battery case for enclosing at least one cell in contact with an electrolyte; a positive post and a negative post connected to the at least one cell and protruding from the case; the case having a recess shaped to receive an electronic battery performance enhancement device (EBPED); and a cover that covers the recess and the EBPED when received in the recess such that the EBPED, including positive and negative leads of the EBPED when connected to the positive post and the negative post, are beneath the cover.

  • Patent number: 4279711
    Abstract: An improved process for aqueous electrowinning of metals, using methanol (or another soluble fuel) added to the electrolyte, a catalytically active platinum mesh or platinum-plated titanium anode and periodic current reversal, in order to maintain a low anodic potential, and hence, a cell voltage and energy consumption lower than in conventional processes. Examples illustrate the electrowinning of zinc and copper from sulfuric acid-sulfate electrolytes, but the process applies to other metals. Also disclosed is the use of an ion-exchange membrane in combination with the above features, in order to decrease the loss of fuel from the anolyte and to minimize the effect at the anode of impurities present in the catholyte.
