CoNiO2/Ti3C2Tx composite was prepared by a facile co-precipitation method and subsequent heat treatment. The as-prepared samples were characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, nitrogen adsorption-desorption measurement, cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The results demonstrate that CoNiO2/Ti3C2Tx composite with a CoNiO2∶Ti3C2Tx mass ratio of 30∶1 exhibits the optimum electrochemical performance. The specific capacitance of CoNiO2/Ti3C2Tx composite is 389 F/g at a current density of 1 A/g, which is approximately 6 times greater than that of Ti3C2Tx. CoNiO2/Ti3C2Tx composite has the specific capacitance of 309 F/g when the current density increases to 20 A/g, and shows a cycle stability with 82% capacitance retention after 1 500 charge-discharge cycles at a current density of 10 A/g.
