STUDY ON ELECTROCHEMICAL PROPERTIES OF FeS_2 IN ROOM TEMPERATURE MOLTEN SALT

摘要

In this paper, 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.
