Abstract
Cells with cupric oxalate cathodes bonded with polystyrene and magnesium alloy AZ61 anodes were discharged at room temperature. The cathode current efficiency was approximately 75% to a 0.8 V cut-off at an apparent current density of 10 mA cm−2. Cells with sulphur-cupric oxalate cathodes showed discharge performance at higher voltages with higher efficiences than those without sulphur. The use of different oxalate samples appeared to result in no significant difference in performance. The samples were either obtained commercially or prepared by precipitation. The cathodic behaviour of cupric oxalate was also investigated by potential sweep voltammetry with a slow sweep rate. In sodium chloride solutions a double peak was obtained on the voltammogram. When the stoichiometric quantity of sulphur was added to the cupric oxalate active material, it gave a main and two smaller peaks. The possible reactions are discussed.
