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...

A lithium-ion battery is primarily composed of a cathode, anode, electrolyte, and separator. During charging, lithium ions de-intercalate from the cathode material, migrate through the electrolyte, and intercalate into the anode material. During discharging, lithium ions move in the reverse direction, de-intercalating from the anode and returning to the cathode through the electrolyte. This repeat...

Lithium plating refers to the detrimental phenomenon where lithium ions fail to intercalate into the graphite anode during charging processes, instead undergoing electrochemical reduction to form metallic lithium deposits. This results in the formation of characteristic silver-gray lithium metal layers or dendritic lithium crystals on the anode surface. Conventionally, battery disassembly has been...
