چکیده انگلیسی
A series of AgCuO2 samples are prepared and tested as alkaline cathode materials for primary batteries. AgCuO2 discharges via four equivalent-charge reduction processes, the rate capabilities of which are determined. At ambient temperature AgCuO2 displays superior rate capabilities for the two highest voltage processes. For all samples, the rate capability of the two lower voltage processes is always superior to those at higher voltage. This is due to the electrode intrinsically doping itself with elemental silver during discharge as part of the second reduction process. The electrode compares favourably with commercial electrolytic manganese dioxide but is prone to self-discharge, the kinetics of which are also discussed.
