Definitions

  • the invention relates generally to lead alloys and in particular to the use of a lead alloy for solid and gridtype electrodes in electrolytic plant and lead accumulators.
  • lead as electrode material for electrolytic plant is uneconomical in certain cases because of too marked corrosion in the case of cathodes.
  • the material for grid anodes in lead accumulators has hitherto generally been a hard lead alloy of varying composition, particularly one having antimony as a constituent.
  • Grid anodes of conventional lead alloys exhibit wear and fatigue phenomena after a fairly short period of time and this markedly restricts the life of the accumulators. Some of these defects are for example corrosion, cathode poisoning by the antimony content, too low specific elongation and many others.
  • electrode material based on lead and lead alloys for a. electrochemical and electroplating plant and b. lead accumulators I can be further improved in its efficiency and life when it contains palladium (Pd) as a component of the alloy.
  • Pd palladium
  • the use of an electrode of lead alloyed with palladium has proved to be superior to the use of lead alloys hitherto used, particularly as anodes for lead accumulators.
  • the superiority and greater efficiency of such an electrode containing palladium as a component of the alloy is not lost when palladium is used in combination wit other known alloy components for lead.
  • a lead alloy preferred according to the invention as an electrode material consists of 0.05 to 0.15 percent by weight of copper (Cu), 0.05 to 0.15 percent by weight of tin (Sn) and 0.05 to 0.2 percent by weight of palladium (Pd), the remainder being lead and the usual impurities.
  • the alloy according to the invention has improved resistance to corrosion by sulfuric acid which commends its use as an anode in the case of sulfuric acid as electrolyte generally and particularly as grid material for the anodes of accumulators.
  • FIG. 2 shows the cathodic portions of current density/potential curves (a) of fine lead and (b) the alloy according to the invention in battery acid of a density of 1,26 g/ccm.
  • the gi'iils cif the anodesof lead accumulators not only is good corrosion resistance desirable but also adequate strength and the lowest possible specific elongation.
  • the alloy according to the invention satisfies these requirements and is therefore superior to the alloys previously used for the same purpose.
  • An article of manufacture comprising a grid electrode consisting essentially of 0.05 to 0.15 percent by weight of copper, 0.05 to 0.15 percent by weight of tin, and 0.05 to 0.2 percent by weight of palladium, the remainder being lead and the usual impurities.
  • An article of manufacture comprising a grid electrode serving as an anode for lead accumulators, said electrode consisting essentially of 0.05 to 0.15 percent by weight of copper, 0.05 to 0.15 percent by weight of tin, and 0.05 to 0.2 percent by weight of palladium, the
  • An article of manufacture comprising a grid electrode serving as an anode in electrolytic and electrochemical cells containing sulfuric acid as the anolyte, said electrode consisting essentially of 0.05 to 0.05 percent by weight of copper, 0.05 to 0.15 percent by weight of tin, and 0.05 to 0.2 percent by weight of palladium, the remainder being lead and the usual impurities.
