Abstract

Sr(OH)2 and/or Ba(OH)2 (I) is used as auxiliary substance in title compsn. consisting of Zn and/or Zn cpds. (II) as the electrochemically active compsn. and auxiliary substances mixed therewith, which form scarcely sol. cpds. with the Zn passing into the electrolyte on discharge. Pref. cpds. are alkaline earth hydroxides.
