【摘要】：为更详尽地解释电极内部发生的导电过程、电解液浸入过程和化学催化过程,使用数字图像相关的方法对电极内部各成分的分布情况进行模拟,使电极内部各材料的分布与连通性直观可见,以帮助设计具有不同优势的空气电极,并在导电性、浸液量与催化性能方面进行验证。电极的导电性随着石墨所占比例的增加而增强;电极的吸液能力随着活性炭含量的增加而增强。当石墨、乙炔黑、活性炭与Mn O2的质量比为1∶1∶4∶2时,Mn O2有最合适的催化区域。
[Abstract]:In order to explain in more detail the conduction process in the electrode, the electrolyte immersion process and the chemical catalytic process, the distribution of the components in the electrode was simulated by using the digital image correlation method. Make the distribution and connectivity of materials within the electrode visible, to help design air electrodes with different advantages, and in conductivity, The conductivity of the electrode increases with the increase of the proportion of graphite, and the absorbency of the electrode increases with the increase of activated carbon content. When graphite, acetylene black, acetylene black, graphite, acetylene black, graphite, acetylene black, graphite, acetylene black, graphite, acetylene black, graphite, acetylene black, When the mass ratio of activated carbon to MnO2 is 1: 1: 4: 2, MnO2 has the most suitable catalytic region.
