The preparation of electrode is the most critical part in the whole process, and the quality of electrode directly affects whether the next step can be carried out. Slurry preparation is a non-Newtonian high-viscosity fluid formed by mixing living matter, adhesive, solvent, thickener and other powders evenly. The fluid needs to have a certain viscosity, good fluidity and a small enough particle size. What kind of equipment is needed for the preparation of electrode to meet the requirements?
