Cycling Behavior of Binder-Free Graphite-Lithium Intercalation Anode In AICI3-EMIC-LiCI-SOCI2Room-Temperature Molten Salt

Abstract

The electrochemical behavior of binder-free carbon anode, comprising of only artificial and natural graphite (AG and NG) particles, for intercalation and deintercalation of lithium ion <TEX>$(Li^+)$</TEX> in aluminum chloride (AICI_3)-I-ethyl­3-methylimidazolium chloride (EMIC)-lithium chloride (LiCl)-thionyl chloride <TEX>$(SOCI_2)$</TEX> room-temperature molten salt (RTMS) was studied. Binder-free carbon electrodes were fabricated using electrophoretic deposition (EPD) method. The binder-free carbon anodes provided a relatively flat charge and discharge potentials <TEX>$(0\;to\;0.2V\;vs.\;Li/Li^+)$</TEX> and current capabilities <TEX>$(250-340mAh{\cdot}g^{-1})$</TEX> for the intercalation and deintercalation of <TEX>$Li^+$</TEX>. Stability of the binder-free carbon anodes for intercalation and deintercalation of 50 cycles was confirmed.
