- •
EIS is able to investigate pore structure and pore shape.
- •
Results are reliable when several materials and porosities are compared.
- •
Porosity and electrode loading define pore resistance for a given material.
- •
Material particle shape strongly affects pore resistance.
- •
Flaky materials exhibit higher pore resistance and bottle-necked pores
