【 摘 要 】
Carbon aerogels (CAs) were prepared via a sol-gel process by polymerization of phloroglucinol, resorcinol and formaldehyde using 2,4-dihydroxybenzoic acid as catalyst with freeze-drying. The electrochemical properties were characterized using cyclic voltammetry, galvanostatic charge-discharge measurements and electrochemical impedance spectroscopy (EIS). The specific capacitance of corresponding CAs was up to 131 F g-1 and 105 F g-1 at the density of 0.5 A g-1 and 1.0 A g-1, respectively.
