A nano interlayer spacing and rich defect 1T-MoS as cathode for superior performance aqueous zinc-ion batteries.

Aqueous Zn-ion batteries (ZIBs) are considered very promising alternatives to lithium-ion batteries. However, the low reversibility and slow diffusion of zinc ions in the positive electrode limit their commercial applications. Herein, we successfully prepared the metallic 1T phase of MoS (1T-MoS) with a nano interlayer spacing of 1.
