Current-Density Effects in Single-Pore Electrodes.
Abstract
A single-pore cadmium electrode has been used to simulate the negative electrode of a nickel-cadmium cell. During the course of charge-discharge cycle operation the electrode capacity increased gradually from 1.0 to 26.0 milliampere-minutes over a period of 5 weeks. Analysis of the discharge current-potential-time data show that the major portion of the electrode polarization can be described by considering the increased resistance to ionic current across a layer of cadmium hydroxide which uniformly forms on the inside of the single-pore electrode. The consequences of this work to the improved design of battery electrodes are discussed. (Author)
