Enhancing aqueous zinc-ion battery performance through a dual-mechanism strategy

Abstract

The development of a high capacity electrode in aqueous rechargeable zinc ion batteries has attracted extensive interest. Herein, ammonium molybdenum sulfide hydrate (N-MoS_x) nanospheres containing S–S bonds are reported. The N-MoS_x/Zn system exhibits a high reversible capacity of 135.64 mA h g⁻¹ and excellent long-term cyclability. Moreover, an interesting dual mechanism with insertion of Zn²⁺ and the breakage/formation of disulfide bonds is demonstrated.
