As the quality of the coke available for production of anodes is deteriorating, future production will rely on cokes that are more isotropic with higher impurity levels than traditional raw materials. The purpose of this work was to improve the understanding of the electrochemical reactivity and wetting properties in relation to the quality of the coke. Electrochemical reactivity is affected by anode properties such as anode:electrolyte wetting, which depends on the polarization of the samples. Pilot anodes were fabricated from single source cokes; one anisotropic coke low in impurities, and one isotropic coke with significantly higher impurity levels. Electrochemical characterization included chronopotentiometry, cyclic voltammetry and impedance spectroscopy. Wetting properties were studied by the sessile drop technique, for polarized samples by a dedicated wetting apparatus, and by computed tomography images of frozen electrolyte films.
