Different discontinuously and continuously working dispersing devices were investigated to determine their influence on the structural and electrochemical properties of electrodes made from commercial LiNi1/3Co1/3Mn1/3O2 (NCM) cathode active material. A laboratory-scale dispersing device was compared with a discontinuously working laboratory kneader and a continuously working extruder, both using 50% less solvent than the dissolver process. Rheological, mechanical, structural, conductive, imaging, and electrochemical analyses (C-rate test, long-term cycling) were carried out. The dispersing method and time were found to have a considerable impact on the structure and electrochemical performance. The continuous extrusion process resulted in good performance with more than 20% higher specific capacity at elevated C-rates compared with the discontinuous process. This can be attributed to better deagglomeration of the carbon black in the slurries, also resulting in 60% higher electrode conductivity. On top of these positive results, the changes in the drying step due to the reduced solvent use led to a 50% decrease in the time required for the constant-drying-rate period. The continuously working extrusion process was found to be most suitable for large-scale, cost-efficient, environmentally friendly production of slurries for lithium-ion battery electrodes.
