英文摘要	本文采用液相法、热分解MnCO3法以及电解沉积法制备不同二氧化锰粉末，并将其与活性炭复合，应用于水系超级电容器. 使用X射线衍射（XRD）、扫描电子显微镜（SEM）技术对材料形貌进行表征. 使用循环伏安法以及恒流充放电法对其电化学性能进行测试. 实验数据表明，α-MnO2（质量分数70%）掺杂活性炭电极的最大比容量为151 F•g-1，β-MnO2（质量分数60%）掺杂活性炭电极的最大比容量为172 F•g-1，γ-MnO2（质量分数50%）掺杂活性炭电极的最大比容量为141 F•g-1，但二氧化锰粉末对电极内阻的影响呈无规律性.; In this work, the manganese dioxide (MnO2) materials were prepared by solution approach at low temperature, thermal decomposition and electrochemical deposition. The actived carbon (AC) and MnO2 composite electrodes were used for aqueous supercapacitors. The morphologies and structures of the prepared materials were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), and the electrochemical behaviors were tested by cyclic voltammetry (CV) and galanostatic charge-discharge tests. Electrochemical test data show that the maximum specific capacitances of 151, 172 and 141 F•g-1 were obtained with the contents of MnO2 being 70, 60 and 70% in the composites, respectively. However, the influence of MnO2powder on the electrode impedance was not straightforward.; 国家自然科学基金（No. 21103085）及江西省教育厅科技落地计划项目（No. DB201101397）资助; 作者联系地址：南昌航空大学材料科学与工程学院，江西南昌 330063; Author's Address: School of Material Science and Engineering, Nanchang Hangkong University, Nanchang 330063, China; 通讯作者E-mail：1353278219@qq.com
