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...

Lithium-ion batteries (LIBs) are the powerhouse of modern electronics and electric vehicles (EVs), and their performance hinges on the cathode materials. Among these, ternary cathode materials such as NCM (Nickel-Cobalt-Manganese oxides) and NCA (Nickel-Cobalt-Aluminum oxides) dominate due to their balanced energy density and stability. However, varying the ratios of nickel (Ni...

1. Process Principles Stacking Process: Anode and cathode sheets are cut to specified dimensions, then laminated with separators to form unit cells. These unit cells are stacked in parallel to create battery modules. Winding Process: Pre-cut anode sheets, separators, and cathode sheets are wound in a defined sequence around a fixed mandrel, compressed into cylindrical, elliptical, or prismatic sha...

Low cell capacity is an intuitive judgment based on comparing the post-formation discharge capacity with the design value. If the measured capacity falls below the design specification, the first step is to verify whether the formation process parameters are correctly set (e.g., discharge current, charge duration, cutoff voltage, and formation temperature). ① If the formation steps are confirmed c...
