Summary: In this study, a facile template strategy is proposed to construct a novel composite cathode of carbon nanotubes intertwined with porous VO2-V2O5 heterostructured microfibers. The as-fabricated composite exhibits enhanced specific capacities and stable cyclic performance when used as a cathode for aqueous zinc-ion batteries (ZIBs). These enhancements are attributed to the porous, heterostructured, and high-conductive structure as well as the strong interaction between carbon nanotubes and VO2-V2O5 microfibers.

Summary: Nitrogen doping enhances the capacitive performance of zinc-ion hybrid supercapacitor by promoting pseudocapacitive reactions through lowering the energy barrier for the change of oxidation states of carbonyl moieties. The as-constructed zinc-ion hybrid supercapacitors, with nitrogen/oxygen dopants and 3D interconnected hierarchical porous carbon matrix, exhibit high gravimetric capacitance and excellent rate capability.

Summary: In this study, MoS2/Ti3C2Tx composites were successfully constructed using a one-step hydrothermal method, where two-dimensional MoS2 nanosheets were grown on monodisperse Ti3C2Tx MXene layers. Due to the high ionic conductivity and good hydrophilicity of Ti3C2Tx, MoS2/Ti3C2Tx composites exhibited improved electrolyte-philic and conductive properties, resulting in reduced volume expansion effect of MoS2 and accelerated Zn2+ reaction kinetics. As a result, MoS2/Ti3C2Tx composites showed high voltage and excellent discharge specific capacity, 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.
