摘要
采用活性电沉积的方法共沉积硫化铁电极,并研究其在室温熔盐中的嵌锂行为.循环伏安及充放电结果表明,硫化铁电极在室温熔盐中具有较高的活性和稳定性.结果显示,硫化铁嵌锂过程分两步骤进行,第一步骤是一个可逆反应的过程,而第二步为不可逆过程.
FeS 2 electrodes have been prepared by using reactive codeposition methods. The electrochemical performances of FeS 2 were studied in LiCl buffer Lewis neutral 1 methyl 3 ethylimidazolium chloride (MeEtImCl)/AlCl 3 (room temperature molten salt) melts. The results show that FeS 2 electrodes possess reversible Li ion intercalation and deintercalation behavior in the first step two electron processes.
