N-Ti3C2 nanomaterials were prepared by a simple one-step hydrothermal method and applied to electrochemical capacitors. The experimental results show that N-Ti3C2 has an accordion-like layered structure, and N successfully enters and distributes uniformly on the Ti3C2 matrix. The electrochemical tests show that the maximum specific capacity of N-TisCx electrode is 156F/g (5mV/s), and it has good rate performance and cycle stability. The excellent electrochemical properties of N-TI3C2 nanoelectrodes are derived from: the unique two-dimensional conductive network of N-Ti3C2 matrix accelerates the intrusion of electrolyte and electron transfer: the introduction of N expands the crystal surface spacing, improves the intercalation pseudocapacitance of K+ and provides additional pseudocapacitance; The high electrical conductivity and contact properties of N-Ti3C2 improve the electron transport rate and provide more surface active sites; The synergistic effect of the above factors effectively promotes the improvement of capacitive performance.
