A binder-solvent solution was prepared by adding 5 wt. % of polyvinylidene fluoride as binder into 95 wt. % of anhydrous butyl acetate and then mixed at 500 rpm for overnight to ensure the binder was well dissolved in the solvent. To prepare the electrode slurry, 3 wt. % of the targeted dried electrode composition was calculated, and the corresponding amount of binder-solvent solution was added to the plastic cup containing the dry cathode mixture with different amounts of solvent to reach the respective solid content (SC) of 48 %, 50 % and 52 %. The slurry was then mixed in the planetary mixer at 2000 rpm for 7 min. After completion, the slurries were then casted on Al foil using a doctor blade with a 100 µm comma gap for AM1 and 300 µm comma gap for AM2, as the AM2 resulted in mechanically unstable thin electrodes that short circuited when casted with 100 µm doctor blade. The casted electrodes (Figure ) were dried in a vacuumed oven at 60 °C for overnight. All materials used were already dried and all procedures were handled at Umicore's dry room with a dew point of -69 ±2 °C.
