Product Overview
This all-in-one electrolyte processing system combines high-precision vacuum injection and controlled standing into a single, compact platform. Engineered to eliminate electrolyte degradation and trapped micro-bubbles during cell assembly, the unit executes automated pre-evacuation, precise volumetric dosing, and programmable soaking cycles. By integrating these critical workflow stages, the equipment prevents electrolyte exposure to atmospheric moisture, ensures rapid and thorough separator wetting, and accelerates cell stabilization.
Designed primarily for battery research laboratories, pilot production lines, and electrochemical device manufacturing, this system accommodates a versatile array of formats including cylindrical cells, supercapacitors, coin cells, and pouch cells. Its streamlined footprint and sealed fluidics enable direct integration into inert atmosphere glove boxes or cleanroom dry rooms, supporting sensitive chemistries that require stringent environmental control.
Constructed with premium 304 and 316 stainless steel contact surfaces and industrial-grade pneumatic controls, the equipment offers dependable repeatability under continuous laboratory and pilot-scale operating schedules. Its robust vacuum containment and precision metering pumps deliver long-term mechanical reliability, providing development teams with consistent data and repeatable cell-to-cell quality across every experimental batch.
Key Features
- Integrated Vacuum Dosing and Soaking: Combines electrolyte injection and pressurized soaking cycles within a unified chamber, significantly shortening processing times while enhancing separator and electrode wetting across all cell formats.
- High-Precision Volumetric Metering: Advanced quantitative dispensing mechanism achieves tight dosing accuracy of ±0.5% across a wide range of 0.2 ml to 100 ml (0.2 g to 100 g), ensuring exceptional consistency between individual cells.
- Adjustable Multi-Stage Parameters: Full digital control allows operators to fine-tune pre-vacuum depth, dispensing speed (0.1 to 20 ml/s), injection volume, and soaking dwell pressure to match specific slurry porosity and electrolyte viscosity.
- Corrosion-Proof Fluid Architecture: All critical fluid path components, nozzles, and structural fittings are crafted from high-grade SUS304 and SUS316 stainless steel coupled with chemical-resistant hoses to withstand aggressive organic solvents and corrosive salts.
- Glovebox and Dry Room Ready: Compact modular chassis with a separable control console enables effortless installation inside standard inert gas gloveboxes (Argon/Nitrogen) or low-dew-point dry rooms without compromising enclosure seals.
- Multi-Cell Batch Capacity: Features dedicated precision fixtures capable of holding up to 35 cylindrical cells simultaneously across various standard form factors, maximizing throughput for pilot-scale batches.
- Intelligent PLC Touchscreen Interface: User-friendly programmable logic controller with an intuitive color touch interface stores customizable process recipes and delivers automated one-touch operational cycles.
- Vacuum-First Injection Workflow: Employs an efficient pre-evacuation sequence down to -98 kPa prior to fluid delivery, preventing air entrapment within tightly wound electrode rolls and promoting immediate capillary absorption.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Cylindrical Lithium-Ion Cells | Automated vacuum injection and soaking for standard cylindrical formats such as 18650, 21700, and custom dimensions up to 35 mm OD. | Accelerates electrolyte uptake across tightly wound jelly rolls, eliminating dry spots and reducing formation cycling scrap rates. |
| Supercapacitor Pilot Assembly | Rapid electrolyte saturation for high-surface-area porous carbon electric double-layer capacitors (EDLCs). | Deep vacuum evacuation removes micro-air pockets within high-capacitance electrode matrices for lower equivalent series resistance (ESR). |
| Next-Generation Solid-State & Semi-Solid R&D | Precision dosing of gel polymers and specialized liquid electrolyte carriers under an inert glovebox atmosphere. | Prevents atmospheric moisture contamination, preserving sensitive lithium metal anodes and exotic electrolyte additives. |
| Pouch Cell Electrolyte Metering | Non-vacuum injection tailored for fragile aluminum laminated pouch formats prior to final vacuum pre-sealing. | Delivers exact dosing accuracy (±0.5%) without risking blister expansion or seal damage from chamber vacuum cycles. |
| Coin Cell and Button Supercapacitor Testing | Micro-volume quantitative dispensing (down to 0.2 ml / 0.2 g) for academic screening and novel material formulation evaluations. | Eliminates manual pipetting errors and ensures reproducible electrochemical impedance spectroscopy (EIS) baselines. |
