Compared to the solvent-based manufacturing process, Solvent-Free (SF) manufacturing processes of LIB electrodes have gained increasing popularity due to its numerous advantages . SF processes eliminate the use of solvents in the mixing of the materials, thereby circumventing the energy-intensive drying step in the conventional wet processing: this has the potential to reduce the energy consumption of the total LIB cell manufacturing process for around 45 %-47 % according to some estimations . Examples of SF processes include among others, dry mixing and coating (implying polymer fibrillation and direct pressing) , electrostatic spraying 24 and 3D printing (Direct Ink Printing or Fused Deposition Modeling) .
