Study on electrochemical properties of FeS2 in room temperature molten salt

摘要

In this paper, FeS2 electrodes have been prepared by using reactive codeposition methods. The electrochemical performances of FeS2 were studied in LiCl buffer Lewis neutral 1-methyl-3-ethylimidazolium chloride (MeEtImCl)/AlCl3 (room temperature molten salt) melts. The results show that FeS2 electrodes possess reversible Li ion intercalation and deintercalation behavior in the first step two electron processes.
