Synthesize the Carbon/nickel oxide compound aerogel with the raw material 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℃.This kind of electrode has typical capacitance properties

the specific capacitance is about 263F/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 in this paper also.
