For pouch cell research, an automatic stacking machine is the most critical tool for transitioning from single-layer prototypes to multi-layer high-energy cells. These machines automate the precise "Z-fold" layering of cathodes, anodes, and separators, ensuring the alignment and tension required for high-performance electrochemical testing. The separator is supplied as a continuous web from a tension-controlled roll, while pre-cut anode and cathode sheets are inserted into the folds from opposite sides. This creates a compact, interconnected stack that is superior to simple manual layering.
