Abstract
Zinc ion batteries (ZIBs) have attracted extensive attention for their high safety and environmentally friendly nature, and considerable theoretical capacities. Due to its unique two-dimensional layered structure and high theoretical specific capacities, molybdenum disulfide (MoS(2)) presents as a promising cathode material for ZIBs. Nevertheless, the low electrical conductivity and poor hydrophilicity of MoS(2) limits its wide application in ZIBs. In this work, MoS(2)/Ti(3)C(2)T(x) composites are effectively constructed using a one-step hydrothermal method, where two-dimensional MoS(2) nanosheets are vertically grown on monodisperse Ti(3)C(2)T(x) MXene layers. Contributing to the high ionic conductivity and good hydrophilicity of Ti(3)C(2)T(x), MoS(2)/Ti(3)C(2)T(x) composites possess improved electrolyte-philic and conductive properties, leading to a reduced volume expansion effect of MoS(2) and accelerated Zn(2+) reaction kinetics. As a result, MoS(2)/Ti(3)C(2)T(x) composites exhibit high voltage (1.6 V) and excellent discharge specific capacity of 277.8 mA h g(-1) at 0.1 A g(-1), as well as cycle stability as cathode materials for ZIBs. This work provides an effective strategy for developing cathode materials with high specific capacity and stable structure.
