PLAQUE SURFACE-AREA MEASUREMENT

A method to accurately measure the electrolyte/electrode interfacial area of nickel plaque used in nickel/cadmium battery cells is described. Conventional methods, such as the BET gas adsorption technique (Brunnauer, Emmett, and Teller method) and galvanostatic methods, fail to give exact measurements. The BET method yields the area penetrated by the gas (which is not identical to the electrolyte/electrode interfacial area), and galvanostatic measurements are complicated by faradaic currents.
