摘要
钙质添加剂与锌酸根形成难溶的Ca[Zn(OH)3]2,可延长锌负极的寿命,改善锌镍电池的高温存放性能,提高荷电保持率并延长放电时间。加入钙质添加剂的锌负极循环100次的容量几乎不衰减。添加氢氧化钙、木质素磺酸钙及无钙质添加剂的电池,荷电保持率分别为68.69%、57.05%和52.32%,放电时间分别为34.00 min、39.09 min和31.29 min。
Calcium additive could react with Zn（OH）42- to form Ca[Zn（OH）3 ]2 with stable electrochemical performance, which could prolong the life of zinc anode, improve the high temperature storage performance of nickel-zinc battery, enhance the charge retention rate and prolong the discharge time. The capecity of zinc anode with calcium additive hardly reduced in 100 cycles. The charge retention rate of battery with Ca（ OH）2, calcium lignosulfonate and without calcium additive was 68.69%, 57.05% and 52.32%, respectively, t he discharge time was 34.00 min, 39.09 min and 31.29 min, respectively.
