Product Overview
This manual winding machine is engineered for precision prototyping and low-volume manufacturing of energy storage devices. Designed to integrate cathode, anode, and separator layers into uniform jelly rolls, the system accommodates supercapacitors, cylindrical battery formats, and flat pouch cell configurations. By combining tactile manual alignment with motorized winding control, this equipment bridges the gap between laboratory benchtop R&D and pilot-line electrode fabrication.
Built to handle delicate battery electrodes and ultra-thin separators without tearing or misalignment, the unit delivers exceptional dimensional accuracy. Researchers and battery development engineers rely on this winding system to evaluate novel active materials, binder systems, and solid-state or liquid electrolyte-separator interfaces under consistent mechanical tension.
With robust mechanical construction and a compact footprint, this benchtop machine provides dependable performance in cleanrooms, dry rooms, and standard laboratory environments. The intuitive control layout and multi-axis mechanical adjustments eliminate operator variability, ensuring repeatable core tightness and edge alignment across continuous experimental cycles.
Key Features
- Multi-Axis Guide Plate Adjustment: The integrated guide ruler and slot plate allow precise three-dimensional adjustment across vertical, horizontal, and fore-aft axes, ensuring exact feed alignment for varying electrode widths.
- Integrated Support Roller System: A precision-machined winding support roller maintains uniform tension across the electrode web, preventing wrinkles, loose cores, and interfacial gaps.
- Reinforced Tailstock Support Bracket: An auxiliary tail bracket stabilizes the winding shaft during motorized rotation, minimizing axial runout and significantly improving core concentricity.
- Bidirectional Stepless Speed Control: Continuous speed adjustment from 0 to 170 rpm combined with forward and reverse rotation capabilities allows operators to optimize winding dynamics for diverse material thicknesses.
- Interchangeable Mandrel Architecture: Rapid tooling changeover supports both round mandrels for cylindrical cells and expandable rectangular mandrels for prismatic pouch cell cores.
- Foot-Switch Motorized Actuation: Ergonomic foot-pedal control allows hands-free rotation management while the operator precisely guides active material and separator feeds.
- Compact Benchtop Footprint: An efficient mechanical profile maximizes dry room bench space while maintaining industrial-grade rigidity and vibration-free operation.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Cylindrical Battery Prototyping | Winding anode, cathode, and separator layers into tight cylindrical jelly rolls up to 35 mm in diameter and 90 mm in length. | Guarantees tight core concentricity and uniform outer diameter for seamless can insertion. |
| Prismatic Pouch Cell Fabrication | Winding flat electrode-separator assemblies for soft-package lithium-ion cells with adjustable width and thickness settings. | Eliminates interfacial bubbling and electrode edge overhang, reducing short-circuit risks. |
| Supercapacitor Core Assembly | Integrating thick activated carbon or porous nanomaterial electrodes with porous separators into dense capacitive cores. | Delivers consistent packing density and low internal equivalent series resistance (ESR). |
| Solid-State & Gel Battery R&D | Processing advanced solid electrolyte composite membranes and thin metallic or alloy foils under controlled manual tension. | Minimizes mechanical stress and micro-cracking on brittle or pressure-sensitive experimental separators. |
| Academic & Industrial R&D Testing | Rapid turnaround of small-batch experimental cell designs using newly synthesized binder formulations or active chemistries. | Accelerates screening cycles with minimal material waste and tool-free parameter reconfigurations. |
