摘　　要：通过简便的两步水热法,在碳布(CC)上直接合成了一种新型的CC/MnO_2/LiMn_2O_4复合材料,并将其用于超级电容器电化学性能研究,结果表明,在0.5 A·g^(-1)的电流密度下,CC/MnO_2/LiMn_2O_4复合材料的比容量达292.91 F·g^(-1),大于CC/MnO_2的比电容(233.52 F·g^(-1)),LiMn_2O_4和MnO_2发挥协同效应提高了超级电容器的电化学性能。A novel CC/MnO2/LiMn2O4 composite was directly synthesized on carbon cloth(CC) in a two-step hydrothermal method for supercapacitors. The electrochemical properties of the material were investigated. At a current density of 0.5 A·g^-1, the specific capacity of the CC/MnO2/LiMn2O4 composite was of 292.91 F·g^-1, which was greater than that of CC/MnO2(233.52 F·g^-1) indicating that the synergistic effect of LiMn2O4 and MnO2 improved the electrochemical performance of the supercapacitor.
