The pore texture of zinc electrodes characterized by impedance measurements
Abstract
Impedance measurements have been applied to the characterization of the pore texture of zinc electrodes used in electrochemical batteries. It is shown that these electrodes are equivalent to cylindrical pore electrodes. The electrode parameters (radius of pore, pore depth and surface density of pores) have been determined from the values of the electrode capacitance, the electrolyte resistance inside the pores and the electrode porosity.
