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...

The voltage of a lithium battery is closely related to the electrode potentials of its cathode and anode materials. Variations in voltage among lithium batteries using different materials primarily stem from the following factors: Impact of Electrode Materials’ Chemical Properties Lithium batteries operate through the movement of lithium ions between the cathode and anode during charging and disch...
