Impedance Spectroscopic Studies of the Porous Structure of Electrodes containing Graphite Materials with Different Particle Size and Shape

摘要

The porous structure of graphite electrodes was studied by applying impedance spectroscopy methods to symmetric cells. The electrode structure was varied by changing the particle size distribution and particle shape of the graphite powders used to prepare the electrodes. In addition electrode parameters such as electrode loading, thickness, and density were varied in order identify their effect on the porous structure.
