摘要
通过向LaNi5储氢舍金电极中添加一定量的壳聚糖金属螯合物,用电化学阻抗谱线分析了其对LaNi5储氢合金电化学性能影响;同时也对LaNi5储氢合金电化学容量以及高倍率充放电性能的影响进行了研究;与LaNi5储氢合金进行了对比,结果表明:添加了壳聚糖螯合物的LaNi5储氢合金其放电平台与高倍率克放电性能都得到了提高,其中添加量为2%时催化效果最好。
The effects of metal chitosan chelate complex addition on the electrochemical performance of LaNi5 hydrogen storage alloy electrode were analyzed by electrochemical impedance curve. Electrochemical capacities and high rate charging and discharging performance of the electrode were studied. The electrode was contrasted with the electrode hydrogen storage of LaNi5 alloy without additions. The results showed that the discharging flat increased and the performances of high rate charging and discharging were improved, the best quantities of metal chitosan chelate compound addition was 20%.
