Challenges in Lithium-Ion-Battery Slurry Preparation and Potential of Modifying Electrode Structures by Different Mixing Processes

The importance and possibilities to modify the morphology by mixing and dispersing is often neglected or underestimated. This Review works out the different opportunities in slurry preparation, using the example of lithium-ion battery (LiB) manufacturing. In this case, also reference is made to possible interactions that are partly described in literature. This contribution outlines three different particle structures and the corresponding process-control variations. Based on SEM pictures, the variation in morphology is shown and the effects of resulting network structures, percolation, electric contacting, and ionic exchange is discussed.
