Reversible Lithium‐Graphite Anodes in Room‐Temperature Chloroaluminate Melts

Abstract

Reduction of a graphite rod electrode in an room‐temperature molten salts leads to reversible lithium intercalation into the reduced graphite lattice. The cycling efficiency of the Li‐graphite electrode ranges from 80 to 90% for current densities of 0.2 to 1 mA cm−2. In the staircase cyclic voltammogram the oxidation process occurs at a potential approximately 1 V positive of the reduction process.
