Abstract: A cathode material rich in 1T-MoS2 (1T'-MoS2) for aqueous zinc ion batteries was successfully synthesized via a one-step hydrothermal method. The characterization results and density functional theory (DFT) simulation calculations indicated that the conductivity of 1T'-MoS2 was significantly higher than that of 2H-MoS2, and 1T'-MoS2 contained abundant sulfur vacancies. That substantially enhances the ion diffusion and charge transfer rates, as well as the electrochemical and kinetic characteristics of the material. Therefore, the initial discharge capacity of the battery assembled with 1T'-MoS2 was as high as 202 mAh·g-1 at a current density of 0.1 A·g-1. In addition, at a high current density (1 A·g-1), the capacity retention rate was 92% after 500 cycles, showing good high capacity and long-cycle stability.
