The electrodes were fabricated using a slurry with a composition of 80:10:10 wt.% active material to carbon black (Super C65, C-NERGY) to polyvinylidene fluoride (PVDF, Solef 6020, Arkema Group) in N-methyl-2-pyrrolidone solvent (NMP, anhydrous, Sigma-Aldrich, 2 wt.% of PVDF in NMP). The slurries were mixed in a planetary speed mixer (Thinky, ARE-310) for 5 minutes at 2000 rpm and then cast on a carbon coated aluminum foil (20 μm, battery grade, Welcos), using a laboratory doctor blade with a wet film thickness of 60 μm. The electrode sheets were dried at 80 °C overnight (Binder ED-115 oven), and 12 mm diameter electrodes were cut with a hand puncher (Hohsen). Each disc electrode was weighed to determine the active material mass loading, which was kept low around 0.80±0.20 mg/cm 2 to minimize the influence of electrode architecture on the electrochemical performance. This was followed by another drying step at 80 °C under vacuum for 16 h before transfer to the glovebox.
