Mn2+/Mn3+电对在不同电极上的电化学性能薛方勤1,王永亮2,张鸿涛1(1.北京市清华大学环境科学与工程系2.蓝星环境工程有限公司,北京 101300)摘 要:采用循环伏安,交流阻抗和旋转圆盘电极方法,研究Mn2+/Mn3+电对在不同的电极材料上的电化学性能.结果表明,Mn3+在石墨电极上岐化反应较少发生,而在炭毡电极上由于存在较多的活性位点而岐化反应的倾向较大,在玻璃炭电极上进行的旋转圆盘电极试验证实了岐化反应的发生.同时确定了在石墨电极上合适的支持电解质硫酸的浓度,计算了Mn2+的扩散系数.
Study of the electrochemical properties of a transition metallic ions modified electrode in acidic VOSO4 solutionWANG Wenhong and WANG Xindong Metallurgical and Ecological Engineering School, University of Science and Technology Beijing, Beijing 100083, China摘 要:Graphite material was used as the electrode for an all-vanadium redox flow battery......
on electrode material performance of MH-Ni batteries were investigated by using SEM, EDAX and XRD. The results indicate that with the ultrasonic time increasing, there are obvious dispersing phenomena in the positive and negative electrodes. This can make the inertia oxidation layer break off from the negative electrode, and the fresh surface comes out. These changes can increase the reaction centers......

Ordered Mesoporous Carbon/SnO2 Composites as the Electrode Material for Supercapacitors刘萍,徐菁利College of Chemistry and Chemical Engineering,Shanghai University of Engineering Science摘 要:A series of composites as electrode materials for supercapacitors were prepared via incipient wetness impregnation method utilizing ordered mesoporous carbon (OMC......
during luminous working hours. Electroless Ni-P-Zn depositions improved the discharge characters of the electrodes.With the concentration of zinc in the deposition rising to 4wt%, electrode sputter was largely restrained. The thickness of the deposition also influenced the discharge characters of the electrode. To avoid electrode sputter, the concentration of zinc has to rise with the thickness......
