The low solubility of calcium zincate produced from the chemical reaction of zinc oxide and calcium hydroxide in alkaline solution can improve the cycling life the zinc electrode , and the discharge capacity will tend to be stable . furthermore , the effects of la2o3 additives on the electrochemical performances of zinc electrodes were investigated . the results shows that the addition of la2o3 , in zinc electrode can improve the area of reduction peak and the hydrogen evolution potential which means the cathodic hydrogen evolution reaction can be hindered 氧化鋅與氫氧化鈣在堿性溶液中化學反應生成的難溶于堿的鋅酸鈣可以使鋅電極的循環壽命得到提高,放電容量也趨于平穩,此外還考察了氧化鑭對鋅酸鈣電極電化學性能的影響,結果表明:添加適量氧化鑭能明顯改善鋅電極的電化學性能,使鋅電極的還原峰電位正移,電極反應可逆性得到改善,同時也可抑制鋅電極析氫反應的發生,提高了鋅電極的陽極電流,對陽極反應有一定的活化作用;同時還可以改善鋅電極的放電特性,增加電極的放電容量。
