气相二氧化硅的分散对胶体电解质电化学行为的影响

Effects of dispersion of fumed silica on the electrochemical behavior of gelled electrolyte

用显微镜观察了气相SiO2粉末的形态,用循环伏安对德国进口的气相SiO2在配胶过程中机械分散和超声波分散对胶体电解液电化学行为的影响进行了研究。发现气相SiO2的适度分散是影响电池容量的关键因素。

The powder morphology of fumed silica was observed using microscope. To study effects of dispersion of fumed silica on the electrochemical behaviors of gelled elctrolyte, the influence of mechanical and ultrasonic dispersing of German fumed silica in gel preparing process was investigated and determined by means of cyclic voltammetry. We found that the appropriate dispersion of fumed silica is a key factor influencing the battery capacity.
