| Abstract: | 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 capacity 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,the discharge time was 34.00 min,39.09 min and 31.29 min,respectively. |
