摘要以钛酸锂（Li₄Ti₅O₁₂）/多壁碳纳米管（MWCNTs）复合材料为负极、活性炭（AC）/镍钴锰酸锂（Li（NiCoMn）O₂）复合材料为正极，组装成混合型电容器并研究其电化学性能。利用扫描电子显微镜（SEM），透射电子显微镜（TEM），X射线衍射仪（XRD），拉曼光谱仪（Raman），热重分析仪（TGA）对电极材料进行分析，通过恒流充放电（GCD）和交流阻抗谱（EIS）研究混合型电容器的电化学性能。结果表明：掺杂适量MWCNTs和镍钴锰酸锂可提高电容器的电化学性能。当MWCNTs质量分数为5%时，在电流密度为0.1 A/g下恒流充放电时比容量达161.5 mAh/g。在0.1~1 A/g时，最大功率密度和最大能量密度分别为993.2 W/kg和52.2 Wh/kg。5000周次恒流充放电循环后，容量保持率在92.2%左右，库仑效率仍有99.1%，展现出较高的能量密度和功率密度，并具有优异的循环性能。

Abstract：The hybrid capacitors were assembled by using lithium titanate/multi-walled carbon nanotubes composite as anode and activated carbon/nickel cobalt manganese acid lithium composite as cathode. The electrode materials were analyzed by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffractomer (XRD), Raman spectrometer (Raman) and thermal gravimetric analyzer (TGA). The electrochemical performance of hybrid capacitors was tested by galvanostatic charge/discharge (GCD) and electrochemical impedance spectroscopy (EIS). The results indicate that the addition of multi-walled carbon nanotubes and lithium nickel cobalt manganese oxide can greatly improve the electrochemical performance of hybrid capacitors. The hybrid capacitors achieve a specific capacitance of 161.5 mAh/g at the current density of 0.1 A/g with an additive of 5% (mass fraction) multi-walled carbon nanotubes. The maximum power density and energy density reach 993.2 W/kg and 52.2 Wh/kg in the current range of 0.1-1 A/g,respectively. The continuous galvanostatic charge-discharge cycling tests reveal that the hybrid capacitors maintain capacitance rate retention of 92.2% and Coulomb efficiency of 99.1% after 5000 cycles. The hybrid capacitors show an excellent cycle performance with high energy and power density.

Key words： multi-walled carbon nanotubes nickel cobalt manganese acid lithium lithium titanate activated carbon hybrid capacitor
