Product Overview

This all-in-one vacuum electrolyte injection and standing system provides an integrated, automated solution for modern lithium-ion and advanced chemistry cell prototyping. By combining deep vacuum pre-evacuation, precision liquid micro-dosing, and multi-stage pressure-controlled soaking cycles into a single rigid chamber, the equipment eliminates electrolyte transfer losses and ensures comprehensive wetting across dense electrode tortuosities.
Designed specifically for pouch cell and small cylindrical cell fabrication, this unit serves battery research institutions, university laboratories, and industrial pilot production lines. It excels in handling volatile, moisture-sensitive, and chemically aggressive non-aqueous electrolytes, delivering consistent liquid infiltration for energy storage devices, consumer electronics battery prototyping, and electric vehicle cell development.
Engineered for continuous reliability under stringent glovebox and dry room operating conditions, the system features heavy-duty pneumatic chamber clamping, corrosion-resistant metallurgical alloys, and industrial-grade programmable logic control. Its robust architecture delivers repeatable dosing accuracy and dependable vacuum retention, providing electrochemical researchers with absolute consistency from batch to batch.
Key Features
- Integrated Injection and Diffusion Processing: Combines vacuum pre-evacuation, targeted liquid electrolyte dispensing, and programmable soaking diffusion inside a single hermetic chamber, streamlining laboratory workflow and eliminating atmospheric exposure risks.
- Precision Fluid Metering Architecture: Achieves an exceptional dispensing accuracy of ±1% with an adjustable dispensing rate of 6 ml/s, accommodating micro-dosing volumes from 0.2 ml to unconstrained capacities tailored to specific pump configurations.
- Optimized Pre-Evacuation Sequence: Evacuates the chamber prior to fluid injection to eliminate internal gas pockets, enabling rapid capillary infiltration into dense separator pores and thick-calendered active material matrices.
- Corrosion-Resistant Fluidics and Chamber Metallurgy: Built with a high-integrity welded aluminum vacuum chamber and critical fluid-contacting components fabricated from grade 304 and 316 stainless steel, ensuring long-term resistance to organic carbonates and lithium salts.
- Pneumatic Guided Chamber Actuation: Features an industrial pneumatic cylinder drive coupled with precision rotary guide bushings, providing smooth vertical movement and repeatable compression for absolute hermetic sealing.
- Optical-Grade Viewing Window: Fitted with a clear, chemical-resistant viewport that permits real-time visual observation of electrolyte wetting, bubble de-gassing, and liquid distribution during active operational cycles.
- Intelligent PLC Touchscreen Automation: Houses an industrial PLC controller with a responsive touchscreen interface, allowing users to fine-tune injection volume, flow speed, vacuum levels, and soak durations up to 9999 minutes.
- Flexible Installation Architecture: Designed with a compact footprint and standard chemical-resistant tubing interfaces, allowing seamless integration inside inert gas gloveboxes or standard dry room environments.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Pouch Cell Pilot Fabrication | Automated vacuum filling and diffusion for standard and customized pouch cells up to 200 × 200 mm. | Ensures uniform wetting across multi-layer electrode stacks without delamination or dry spots. |
| Cylindrical Cell Prototyping | Precision electrolyte dosing for experimental cylindrical battery formats under controlled vacuum conditions. | High volumetric repeatability (±1%) guarantees consistent cell balancing in small-batch testing. |
| Solid-State & Semi-Solid Infiltration | Infusion of liquid or gel-polymer electrolytes into dense, low-porosity composite separator structures. | Deep vacuum pre-evacuation drives fluid deep into tortuous micro-pores for low internal resistance. |
| Sodium-Ion Battery Research | Electrolyte injection using highly corrosive or novel ester- and ether-based solvent formulations. | SUS316 and welded aluminum components prevent chemical corrosion and fluid contamination. |
| Supercapacitor Electrolyte Impregnation | Vacuum de-aeration and high-speed filling of high-surface-area activated carbon or graphene electrodes. | Multi-stage soaking cycles up to 9999 minutes ensure exhaustive saturation of nanoscale pore networks. |
| Silicon-Anode Battery Development | Precise micro-volume dispensing (from 0.2 ml) for high-capacity silicon-dominant experimental cells. | Prevents excess electrolyte degradation while providing exact stoichiometry required for SEI formation. |
