The principle of laser cleaning is to utilize the characteristics of laser beam with large energy density, controllable direction and strong convergence ability. The laser interacts with contaminants such as oil stains, rust spots, dust residue, coatings, oxide layers or film layers attached to the workpiece base, and is separated from the workpiece base in the form of instantaneous thermal expans...

In the cutting process, issues such as rapid mold wear, long mold change times, poor flexibility, and low production efficiency often lead to unstable processes, resulting in inconsistent electrode cutting quality and reduced battery performance. Laser cutting, due to its advantages of no vibration deviation, high precision, good stability, and no need for mold replacement, has gradually become ma...

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 ...

The global race for the next generation of energy storage is centered on Solid-State Batteries (SSBs). While the potential for higher energy density and enhanced safety is clear, the transition from lab-scale prototypes to mass production remains a challenge. One of the most critical hurdles is ensuring perfect interface contact between solid electrolytes and electrodes. To bridge this gap, we are...

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 article sy...
