摘　　要：以间苯二酚、甲醛、硝酸镍和无水碳酸钠为原料 ,使用溶胶 凝胶法制备碳 /氧化镍复合凝胶 ,经CO2 超临界干燥及 90 0℃炭化处理 ,得到复合碳气凝胶 ,电化学方法证明这种材料制备的电极具有典型的电容特性 ,采用1mol/LKOH电解液构成电容器单元 ,比电容量达 2 6 3F/g,等效串联电阻小于 1Ω .本文还对这种复合材料的结构形貌进行了探讨 ,分析了其对电容器性能的影响 .Synthesize the Carbon/nickel oxide compound aerogel with the raw material, such as resorcin, formaldehyde, nickelnitrate and anhydrous sodium carbonate, by sol-gel. It becomes aerogel electrode through supercritical drying from carbon dioxide and subsequent pyrolysis in the inert nitrogen atmosphere at 900°C. This kind of electrode has typical capacitance properties, the specific capacitance is about 263 F/g, and the equivalent series resistance is less than 1Ω by electrochemical testing. The structure topotaxy of the compound materials and its supercapacitor characters have been researched also.
