What Is a Battery Stacking Machine vs a Battery manufacturing platform ?
A battery stacking machine assembles alternating anode, separator and cathode layers to form the electrode stack of a battery cell. Depending on the cell architecture, materials and production objectives, the equipment may use individual sheet stacking or a continuous Z-folding process.
In addition to feeding and positioning the layers, a configurable stacking platform can integrate cutting, pressing, wrapping, tab welding, testing, encapsulation and electrolyte filling operations.
In brief : a battery stacking machine creates the layered electrode stack used in pouch cells and other stacked battery designs a battery stacking platform integrates several additional parocesses and one line tests.
Develop Your Stacking Process Without Freezing Its Future Configuration Without Freezing Its Future Configuration
Early-stage battery projects require flexible equipment to test cell designs, validate materials and refine process parameters before industrial scale-up. However, material behaviour, cell chemistry and assembly requirements may evolve considerably during development.
A fixed production system can limit the ability to evaluate new scenarios, use peculiar material or introduce intermediate operations. The Next Gen Line provides a modular starting point that secures the processes already identified while preserving the ability to add, replace or reorganize functions as the project develops.
Are your materials, stack dimensions or future process steps still evolving ?
Our teams can help you define a modular starting configuration without limiting future upgrades.
Next Gen Line : A Modular Battery Stacking Platform
Huguet’s Next Gen Line is a modular battery prototyping platform designed for stack preparation and stacked cell assembly. Embedded stations and connectable modules can be combined to reproduce the assembly sequence required by each project.
R&D and industrialization teams can progressively build their process, assess critical operations and adjust key parameters before preparing for a larger production scale. Each configuration is developed according to the cell format, materials, selected stacking method and targeted level of automation.

Sheet-by-Sheet Stacking
Sheet-by-sheet stacking assembles individually cut electrodes and separator layers in a controlled sequence. This method provides flexibility when testing different layer configurations, materials or stack dimensions. It is particularly relevant for R&D projects requiring frequent adjustments.
Z-Fold Stacking
Z-fold stacking positions electrode sheets within a continuous separator folded alternately around the anode and cathode layers. The method supports separator continuity and repeatable electrode placement, subject to the behaviour of the selected materials.

How Cell Stacking is made with Pouch format ?
A typical pouch cell stacking process includes:
- Material feeding
Electrodes, separators, solid electrolytes or multilayer components are loaded into dedicated magazines or positionned on unwinding mandrels.
- Material preparation
Protective films or carrier materials, if any, can be removed from active sheets.
- Cutting
Laser or mechanical cutting prepares the components to the required dimensions.
- Positioning and alignment
Each component is transferred and positioned before being added to the stack.
- Stack assembly
The electrodes and separators are assembled through sheet-by-sheet or Z-fold stacking. Opposite tab design or design with tabs on the same side.
- Pressing andand finalization
The completed stack can be pressed (optional), wrapped or taped.
- Electrical connection
The process can include current collector crimping and tab welding. Insulation taping (optional)
- Testing, packing and cell filling
Depending on the project requirements, electrical insulation testing, encapsulation, sealing and electrolyte filling operations can also be integrated.
