CoNiO2/Ti3C2Tx复合材料的制备及其电化学性能
Preparation and Electrochemical Performance of CoNiO2/Ti3C2Tx Composites
摘要
Abstract
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 1500 charge?discharge cycles at a current density of 10 A/g.关键词
