Determination of AgCuO2 discharge mechanism in alkaline electrolyte
The alkaline discharge mechanism of (AgCuO2)-Cu-I-O-III 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 AgCuO2 -> Ag2Cu2O3 -> Ag degrees + CuO -> Cu2O -> Cu degrees is proposed based upon analysis of ex situ X-ray powder diffraction patterns of the discharge products.
