Abstract
A theoretical analysis by Mitoff and Charles of electrode processes for an ionic material is criticized and corrected. These authors introduce three separate capacitances into their equivalent circuit where only one need appear. This frequency‐dependent diffusion‐discharge capacitance is calculated incorrectly by Mitoff and Charles, and earlier relevant work is ignored. Partial blocking small‐signal theory is used to show that Mitoff and Charles's experimental results on three different ionic materials can quite possibly by understood using such an approach, contrary to these authors' expectations.
