Stable divalent silver oxide-containing cathode material

摘要

The stable AgO-containing cathode material for electro­chemical cells, preferably cells containing a zinc anode, shows under X-ray analysis the presence of AgO, Ag₂O, Ag₅Pb₂O₆ and Ag₂PbO₂and when tested by differential scanning calorimetric a thermal stability greater than that of the reactant AgO. The cathode material can be obtained by reacting AgO and lead sulfide in an aqueous alkaline medium at elevated temperature.
