Tailoring V2CTx to form a derivative hybrid by partial oxidation for enhanced lithiation behavior

Utilizing MXene to form the multifunctional derivative is a route to construct high-performance electrode materials. To address this issue, V2CTx MXene was employed to realize a derivative of VOx/V2CTx MXene via a partial oxidation process. Relying on the annealing in the air atmosphere, the controlled oxidation behavior transformed V2CTx MXene partially to V2O5 and formed a derivative hybrid of V2O5/V2CTx 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.
