Measurement of the resistivity of the electrode NiOOH/Ni(OH)2 solid phase active substance during the discharge process

Abstract

The quantitative relation between the resistivity of the solid phase active substance NiOOH/Ni(OH)2 and its bulk resistivity, which can be measured experimentally according to the potential jump when the current is switched on, is established with the simplified mathematical model of a thin porous electrode with a solid phase reagent. The dynamics of the resistivity of the NiOOH/Ni(OH)2 particles in the course of the discharge is ascertained with the help of the proposed method.
