Lithium Ion Battery Z Fold Semi Automatic Stacking Machine for Pouch Cell Fabrication and Battery Research

Product Overview

This semi-automatic Z-fold stacking machine delivers precision layer-by-layer cell assembly for next-generation lithium-ion battery research and small-scale pilot manufacturing. By replacing tedious manual assembly with a synchronized, pneumatically driven reciprocating separator feed, the equipment ensures consistent internal electrode alignment while eliminating edge curl and separator deformation. The integrated constant-tension control mechanism maintains uniform web handling across continuous Z-pattern cycles, providing research laboratories and pilot facilities with a reliable bridge between manual prototyping and high-throughput automated manufacturing.

Designed specifically for pouch cell and solid-state battery development workflows, this unit accommodates a broad spectrum of cathode and anode dimensions. The cantilevered mechanical architecture provides open physical access to the stacking platform, simplifying the manual placement of positive and negative electrode sheets while pneumatic clamps secure each layer in place. It serves academic laboratories, material development centers, and battery prototyping lines requiring rapid turnaround, flexible recipe adjustments, and uncompromised stacking consistency.

Built on a rigid benchtop chassis with industrial-grade pneumatic and electronic controls, this system ensures repeatable structural accuracy under continuous daily cycling. Advanced features such as non-volatile parameter memory retention, digital cycle timing, automatic batch counting, and foot-pedal actuation combine to minimize operator fatigue and prevent parameter drift during long experimental runs. The unit guarantees dependable mechanical reliability, reproducible interfacial contact, and superior cell architecture integrity for rigorous electrochemical testing.

Key Features

• Precision Reciprocating Z-Fold Mechanism: Driven by a smooth pneumatic cylinder assembly, the system automatically translates the separator roll back and forth in an alternating Z-configuration, ensuring flawless layer alignment better than ±0.5 mm without separator wrinkling.
• Active Constant-Tension Control System: Built-in mechanical web tensioners prevent separator sagging, stretching, or uneven edge stress, ensuring consistent interfacial contact across all electrode layers regardless of roll diameter changes.
• Ergonomic Cantilever Design: The open, cantilevered stacking head grants unrestricted hand access to the alignment fixture, allowing operators to insert positive and negative electrode sheets rapidly, accurately, and without physical interference.
• Foot-Pedal Actuated Pneumatic Clamping: Hands-free foot switch triggering controls the left-and-right reciprocating stroke and clamping action, allowing operators to maintain two-handed control over delicate electrode foils and tabs at all times.
• Digital Counting and Auto-Reset Functions: The integrated digital controller tracks completed stacking cycles in real time and features one-touch zero-resetting, eliminating manual counting errors during multi-layer pouch cell builds.
• Non-Volatile Parameter Memory: Automatically preserves operational settings, batch parameters, and timer configurations during power interruptions or equipment shutdowns, enabling immediate resumption of testing without recalibration.
• Broad Dimensional Versatility: Supports pouch cell dimensions from 44 mm × 44 mm up to 200 mm × 150 mm (including tabs) and stack thicknesses up to 12 mm, with modular tooling options available for specialized cell geometries.
• Compact Industrial Benchtop Footprint: Measuring only 512 mm × 820 mm × 580 mm, this self-contained benchtop apparatus integrates seamlessly into standard laboratory spaces, dry rooms, and inert-atmosphere glovebox environments.
