Silver/Silver Chloride Electrodes: Surface Morphology on Charging and Discharging

Abstract

Transport modes were determined from examinations of morphology for electrochemical oxidation and reduction within electrodes consisting of beds of silver spheres 37.2 ~m in diameter in IN KCI and subjected to 5.0 mAcm -2 applied current density. Oxidation proceeded via silver dissolution, probably at dislocation sites, followed by diffusion and, then, deposition of AgCI in characteristic, bulbed mounds which grow together to form layers of ap-proximately
