I. Analysis of Dry Electrode Preparation Technology 1. Introduction to Dry vs. Wet Processes and Material Comparison The traditional wet process involves mixing active material, conductive agent, and binder in a solvent at specific ratios, then coating the mixture onto the current collector surface via a slot-die coater followed by calendering. The dry process involves dry-mixing active particles ...

Electrode slurry preparation is one of the most critical yet underestimated steps in lithium-ion and sodium-ion battery manufacturing. Problems such as particle sedimentation, agglomeration, poor dispersion uniformity, and unstable viscosity often originate at the slurry stage, but their consequences propagate downstream into coating defects, capacity inconsistency, and yield loss. This artic...
