All cells in this study were assembled in a coin cell type electrode stack consisting of a 16 mm Celgard 2325 (dried at 80°C for 12 hours under vacuum) soaked in 100 mL of 1 M NaPF6 EC:DEC (1:1) electrolyte separating the working and counter electrodes. Three types of electrodes were used throughout the work, PW/glassy carbon (GC) coated on stainless steel mesh (212/90 µm, Bopp AG, Switzerland) and HC coated on carbon-coated aluminium foil.
