NOVELTY - Method for preparing high-performance carbon nano/MXene composite fiber, involves dispersing MXene powder for removing metal aluminum components in water to obtain two-dimensional sheet MXene aqueous dispersion, uniformly dispersing carbon nanomaterial in two-dimensional sheet MXene aqueous dispersion to obtain carbon nano/MXene dispersion slurry, and performing wet spinning process on obtained carbon nano/MXene dispersion slurry to obtain high performance carbon nano/MXene composite fiber. USE - The fiber is useful for electrode material. ADVANTAGE - The method is simple, rapid, continuous and easy-to-scale production process, and provides carbon nano/MXene composite fibers with high conductivity and high mechanical strength for improving flexibility of electrode material.
