In the field of power batteries, the discussion surrounding the two main process routes—winding and stacking—has never ceased. In recent years, with the increasing demands for battery energy density, safety, and shape adaptability, the advantages of the stacking process have become increasingly prominent, and its application in prismatic batteries and high-end vehicles has steadily increased. This trend has directly driven the rapid development and technological competition in the stacking equipment market.

The core of the stacking process lies in the stacking precision and efficiency of the electrode sheets. Traditional Z-fold stacking faces bottlenecks in speed and yield, while new processes such as integrated cutting and stacking technology and thermal composite stacking have emerged. These new processes closely integrate electrode sheet cutting and stacking, improving efficiency while reducing burrs and dust generation, aligning with the pursuit of higher safety in next-generation batteries. Equipment manufacturers are focusing on technological breakthroughs in areas such as "single-station high-speed stacking," "multi-station parallel stacking," and "laser cutting and stacking integration," aiming to elevate stacking efficiency to new heights while ensuring micron-level alignment accuracy. This equipment competition, triggered by the evolution of terminal battery technology, is shaping a new landscape in the mid-to-late stages of lithium-ion battery manufacturing.
