The dry composite of slurry consisted of NMC-622 (HEX-10, Umicore) AM, WMSE and Carbon additives (Carbon Super C45) mixed well with a mortar and pestle. the binder of styrene-butadiene-styrene copolymer (SBS) (Sigma -Aldrich) was dissolved in the solvent p-xylene (≥ 99%, Sigma-Aldrich) for 30 minutes at 70°C with continuous mixing. After that, the solvent was left to cool to ambient temperature then the dry composite was added to it and mixed for one hour to formulate the slurry.
