电解液添加剂对密封锌镍电池的影响

Influence of different electrolyte additives on sealed Ni-Zn battery

对密封圆柱形锌镍电池所使用的电解液添加剂进行了研究。考查了氧化锌、柠檬酸、十六烷基三甲基溴化铵和氧化铟等电解液添加剂对锌镍电池充放电曲线、充放电过程中内阻、放电容量以及循环寿命的影响。研究结果表明,和氧化锌相比,柠檬酸、十六烷基三甲基溴化铵和氧化铟作为添加剂可明显提高锌镍电池的充放电性能;在电解液中同时添加氧化铟和氧化锌可提高电池的充放电效率和荷电保持能力,电池的循环寿命也得到提高。同时就电解液添加剂对锌镍电池性能的影响进行了分析。

Different electrolyte additives for sealed Ni-Zn battery were studied. The effects of addtives on Ni-Zn battery＇s charge-discharge curves, resistance, capacity and cycle life were researched. The results show that the charge-discharge performance of Ni-Zn battery with citric acid, Hexadecyltrimethylammonium bromide and indium oxide respectively, is higher than zinc oxide. Especially, the battery with electrolyte saturated by zinc oxide and indium oxide shows excellent charging-discharging performance and charge retention capacity as well as its cycle life. At last the causes of those phenomenon were analyzed.
