Investigation of zinc ion storage of transition metal oxides, sulfides, and borides in zinc ion battery systems

Abstract

Zn-ion batteries have been widely investigated due to their low cost, high safety and eco-friendliness. We comprehensively evaluate the performance of oxides (MoO₃, TiO₂, and Fe₃O₄), sulfides (MoS₂, WS₂, and MnS) and borides (TiB₂ and ZrB₂) in zinc ion battery systems. It is found that MnS is a good alternative cathode material with a reversible capacity of 221 mA h g^-1, while the other materials show different behaviours.
