简介:石墨材料为一节所有钒氧化还原作用流动电池被用作电极,并且电极被转变修改提高它的电气化学的行为的金属性的离子。合成电极高有的一块多孔的石墨比表面区域和高电流密度。金属性的离子改进了的转变修改的电极能催化V的催化作用行为(Ⅱ)-V(Ⅴ)氧化还原作用反应由周期的voltammograms出现了。这篇文章由电气化学的阻抗光谱学(EIS)学习了修改电极的阻抗,并且同意电极由Co~(2+)和Mn~(2+)修改了,这比修改thenon的电极有一个更低的电嗬转移电阻。平均粒子尺寸分发的效果在Warburg阻抗的斜坡被大粒子尺寸分发减少的更低的频率。Co~(2+)的电压效率修改了电极测试房间是81.5%,它比修改thenon的电极的高。
