摘 要:通過(guò)簡(jiǎn)便的兩步水熱法,在碳布(CC)上直接合成了一種新型的CC/MnO2/LiMn2O4復合材料,并將其用于超級電容器電化學(xué)性能研究,結果表明,在0.5 A·g-1的電流密度下,CC/MnO2/LiMn2O4復合材料的比容量達292.91 F·g-1,大于CC/MnO2的比電容(233.52 F·g-1),LiMn2O4和MnO2發(fā)揮協(xié)同效應提高了超級電容器的電化學(xué)性能。 |

Abstract: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. |
Key words:carbon cloth; CC/MnO2/LiMn2O4; electrochemical performance |
