摘要
为了改善锌电极及锌-空气电池的性能,通过对比试验分析了羧甲基纤维素钠(CMC)和聚丙烯酸钠(PAAS)对锌电极电化学性能以及锌-空气电池放电性能的影响。结果表明:采用CMC与PAAS以一定比例混合用作锌膏增稠剂,使锌膏具有良好的电化学性能和电池放电性能。所装配的AA型锌-空气电池采用10Ω恒阻连续放电方式进行放电,终止电压为0.9V,电池的放电时间达到39h以上,在1.235V左右有一个平坦的放电平台,锌粉的利用率为83.1%,电池的放电容量达到4770mAh。
In order to improve the performance of zinc electrode, effect of sodium carboxymethyl cellulose （CMC） and polyacrylate sodium on electrochemical performance of zinc electrode and discharge performance of zinc-air battery were analyzed by contrast experiments. It showed that using the mixture of CMC and polyacrylate sodium as zinc gel binder, zinc electrode and zinc-air battery had better performances than others. AA size zinc-air battery was made with this zinc gel binder. It discharged for 39 h before voltage reached 0.9 V with 10Ω constant load. The discharge curve of the cell had a flat plateau at 1.235 V,utilization of zinc powder was 83.1%. Its discharge capacity reached 4 770 mAh.
