This study improved the discharge specific capacity and cycle stability of ZIBs by preparing V-intercalated MoS2 nano materials, promoting the development of MoS2-based cathode materials and the commercialization of ZIBs.
In general, aqueous Zn-ion batteries (ZIBs) are considered to be ideal candidates over Li-ion batteries due to their high safety and environmental friendliness. ZIBs development is limited by the lack of cathode materials that are suitable for rapid Zn-ion reversibility. In this work, V-intercalated MoS2 (V-MoS2) nano materials were prepared by using a simple one-step hydrothermal method. The unique layered structure and large interlayer of the prepared nanomaterials could effectively reduce the energy barrier of the electrochemical process and enhance the reversible insertion/deinsertion rate of Zn ions during cycling. Electrochemical results indicated that the obtained V-MoS2 cathode could obviously improve the discharge specific capacity and cycle stability of ZIBs. This study promotes the development of MoS2-based cathode materials for batteries and the large-scale commercialization of ZIBs. (C) 2021 Acta Materialia Inc. Published by Elsevier Ltd.
