Abstract

Methods are herein described for monitoring in situ changes in the electrical resistance of a single, spherical (S-)Ni(OH)₂ microparticle electrode as a function of its state of charge. The general approach involves application of 1-2 mV across, and measuring the current through the particle either at a fixed state of charge (static) or during a linear voltammetric scan (dynamic). The data obtained for activated S-Ni(OH)₂ microparticles agreed well with values reported in the literature measured by other means, whereas oxidation of the material yielded as expected a sizable increase in conductivity. Other methods reported in the literature for in situ resistivity measurements of electrodes as a function of the applied potential are also discussed.
