Abstract

Utilizing MXene to form the multifunctional derivative is a route to construct high-performance electrode materials. To address this issue, V₂CT_x MXene was employed to realize a derivative of VO_x/V₂CT_x MXene via a partial oxidation process. Relying on the annealing in the air atmosphere, the controlled oxidation behavior transformed V₂CT_x MXene partially to V₂O₅ and formed a derivative hybrid of V₂O₅/V₂CT_x MXene. As a result, a package of capacity, rate performance, and cyclability can be enhanced. This work explores the derived behavior of MXenes and provides a route for constructing the hybrid with less interface contact. Furthermore, these findings can be extended to other MXene materials.
