Product Introduction
The Semi-Automatic Battery Electrode Stacking Machine MRX-BDP200-A is a compact laboratory and pilot-scale system developed for assembling lithium-ion battery electrodes through a controlled stacking process. It is designed to improve the consistency and productivity of electrode stacking compared with manual assembly, while maintaining a straightforward operating concept suitable for research and small-volume production.
The machine combines separator handling with reciprocating electrode placement to form a Z-fold stacking structure. During operation, the separator film is maintained under controlled tension while the pneumatic mechanism drives its lateral movement. This coordinated motion allows positive and negative electrode sheets to be positioned successively between separator layers to build the required cell structure.
With a benchtop configuration, the MRX-BDP200-A can be installed on a standard working table without requiring a large dedicated production area. The cantilever-style structure provides convenient access to the stacking area, making setup, adjustment, cleaning, and routine maintenance easier for laboratory operators.
The system accepts electrode dimensions from 20 to 200 mm in both length and width and can accommodate a separator roll with a maximum diameter of 250 mm. This relatively broad working range allows battery developers to evaluate different cell formats without changing to a completely different stacking platform.
A digital counter helps operators monitor stacking cycles during repeated experiments or small production batches, while the foot switch provides convenient control of the pneumatic movement. The overall design focuses on practical operation, repeatable stacking motion, and efficient prototype cell preparation rather than the complexity of a high-speed automated production line.

Controlled Separator Handling: A dedicated separator tension control system helps maintain stable film movement during stacking, reducing unwanted slack or excessive tension in the separator path.
Wide Electrode Size Range: The machine supports electrode lengths and widths from 20 to 200 mm, giving battery developers flexibility when preparing cells with different dimensions.
Pneumatic Actuation: The reciprocating mechanism is driven by a pneumatic cylinder, providing a simple and responsive method for controlling separator movement during the stacking cycle.
Foot-Switch Operation: A foot-operated control allows the operator to trigger the pneumatic action without continuously reaching for a manual control, which can make repetitive laboratory work more convenient.
Digital Cycle Counting: The integrated digital counter enables operators to keep track of stacking operations during experiments, prototype preparation, and small-batch trials.

Main Functions
The primary function of the MRX-BDP200-A is to assemble positive and negative lithium-ion battery electrodes into a layered cell structure using a separator film. The machine coordinates separator movement and electrode placement to create a repeated Z-fold pattern.
Before operation, the separator roll is installed on the machine and the electrode dimensions are configured according to the intended cell design. During the stacking sequence, the separator is guided through controlled lateral movement while operators introduce the corresponding electrode sheets at the required positions.
The pneumatic system provides the mechanical movement required for the folding sequence, while the foot switch gives the operator direct control over the actuation cycle. This arrangement allows users to maintain hands-on control over the stacking process while benefiting from mechanically assisted movement.
The MRX-BDP200-A also functions as a practical prototype cell preparation platform. Its adjustable working range enables researchers to manufacture battery samples with different electrode dimensions for material evaluation, cell design optimization, process studies, and small-batch validation.
Specific Application Scenarios
Lithium-Ion Battery Research: The MRX-BDP200-A can be used in battery laboratories for preparing experimental cells after electrode fabrication and before subsequent cell assembly processes.
Pouch Cell Prototyping: Its Z-fold stacking configuration is suitable for development work involving layered electrode assemblies commonly used in pouch-type lithium-ion cells.
Battery Electrode Process Development: Researchers can use the machine to study the influence of electrode dimensions, stacking sequence, separator handling, and cell structure during prototype development.
Small-Batch Cell Production: The semi-automatic design provides a practical option for limited production quantities where a fully automated industrial stacking line would be unnecessary or uneconomical.
University and Research Laboratories: The benchtop structure and relatively simple operating method make the equipment suitable for academic laboratories conducting Battery Materials and cell fabrication research.
Battery Prototype Manufacturing: Cell developers can use the machine to prepare repeated prototype samples while maintaining a more consistent stacking motion than purely manual assembly.
