摘　　要：研究了铝氧化银电池激活初期和放电中后期电解液条件下铝合金电极的性能,分析了含有较高偏铝酸盐浓度时铝合金电极的界面反应,并研制出了高活性铝合金电极。大倍率放电(620 mA/cm^(2))时,采用高活性铝合金电极的单体电池平均电压较采用现有铝合金电极的单体电池平均电压提高了19和36 mV,平均带载析氢速率仅增加了0.078和0.142 mL/(min·cm^(2)),且保持稳定。这为铝合金电极性能提高提供了新的解决思路,对铝氧化银电池比能量的提升具有极其重要的意义。The performance of aluminum alloy electrode under the condition of electrolyte in the early stage of activation and the middle and late stage of discharge of aluminum oxide silver battery was studied.The interfacial reaction of aluminum alloy electrode with high concentration of meta-aluminate,and the high active aluminum alloy electrode was developed.At high rate discharge(620 mA/cm^(2)),the average voltage of the single cell with high active aluminum alloy electrode is 19 and 36 mV higher than that of the single cell with existing aluminum alloy electrode,and the average hydrogen evolution rate with load is only increased by 0.078 and 0.142 mL/(min·cm^(2)),and remains stable.It provides a new solution for the performance improvement of aluminum alloy electrode,which is of great significance for the improvement of specific energy of aluminum silver oxide battery.
