CALCULATIONS OF POTENTIAL DISTRIBUTION OVER THE THICKNESS OF POROUS-ELECTRODES WITH CONSIDERATION FOR BOTH ION AND ELECTRON RESISTIVITIES

The distribution of current and potential over the thickness of an ele ctrode (in solid phase) and the electrolyte, with the specific resisti vity of each phase other than zero, was considered for a one-dimension al model of a hydrophilic porous electrode with rear and front arrange ment of the current collector. Calculations were carried out on the po larization and potential profiles in each phase along the coordinate, and on the dependence of the dimensional current density on the electr ode thickness.
