Determination of AgCuO2 Discharge Mechanism in Alkaline Electrolyte

The alkaline discharge mechanism of Ag I Cu I I I O 2 is characterized at room temperature using linear sweep voltammetry and ex situ X-ray powder diffraction. Four distinct discharge processes are resolved at +0.35, +0.06,-0.28, and -0.56 V (vs. Hg/HgO). A discharge mechanism AgCuO 2 → Ag 2 Cu 2 O 3 → Ag° + CuO → Cu 2 O → Cu° is proposed based upon analysis of ex situ X-ray powder diffraction patterns of the discharge products.
