Sequentially laminates anode, separator, and cathode layers into a controlled stack structure that defines the cell’s internal architecture.
Why this machine:
Its core advantage lies in micron-level alignment accuracy for ultra-thin electrodes (≤0.5mm), which is critical for maximizing the energy density of consumer electronics batteries. This eliminates the risk of micro-short circuits caused by layer misalignment.
Ideal User:
Smartphone and laptop battery manufacturers for whom maximizing active material space within a limited cell volume is a primary design goal.
When to choose: When electrodes are prepared upstream and the final cell quality is defined by layer-to-layer alignment.

This section identifies the Stacking Machine as a core step in pouch and prismatic cell assembly.
Alternating electrode and separator layers are sequentially placed to form the electrochemical core structure.
Packaging focuses on stacking heads, motion systems, and alignment components.
The patented High-Efficiency Electrode Stacking Mechanism introduces parallel pick-and-place motion with coordinated trajectory control.
This increases stacking cadence while preserving placement accuracy required for multilayer cell structures.
