Researchers develop dual-performance anode material for both Li-ion and Li-S batteries

A team at the Paul Scherrer Institute in Switzerland has developed a new type of anode material, MSnS2 (M = Fe, Cu), that is able to cycle in both lithium-ion and lithium-sulfur batteries. A paper on the material is published in the Journal of the Electrochemical Society.

By tuning the potential window, they attained specific charges greater than 750 mAh/g and 500 mAh/g for the Li–S and Li–ion system, respectively, after 400 cycles. They also were able to cycle at 1-C rate (loading: 4 mg/cm2) with a Coulombic efficiency greater than 97%.
