The morphology of the fumed silica was observed under Transmission Electron Microscope TEM. It was found that the diameter of Aerosol A200 was about 10nm, and the fumed silica aggregates easily. The effects of ethylene glycol EG on the electrochemical properties of gel electrolytes have been investigated by means of cyclic voltammetry CV and electrochemical impedance spectroscopy EIS. The results show that adding 1% EG helps to improve the electrochemical property of gel electrolyte. The optimum dispersion times of fumed silica in sulfuric acid solution decrease greatly with the adding of EG.
