Supercapacitor Automatic Electrolyte Injection Machine High Precision Vacuum Electrolyte Filling System

Product Overview

This automated electrolyte injection system delivers industrial-grade precision and volumetric consistency for the assembly of high-performance supercapacitors. Designed specifically for 60-series cylindrical supercapacitor cells and advanced electrochemical energy storage devices, the equipment automates the complete electrolyte filling cycle. By integrating high-vacuum pre-evacuation, precision valveless ceramic metering, and programmable alternating vacuum-pressure soaking cycles, this machine ensures complete, bubble-free wetting of dense electrode matrices while preventing chemical degradation.

Built for demanding pilot-scale manufacturing, commercial production lines, and high-throughput research facilities, the system operates seamlessly within inert gas gloveboxes or dry room environments. The architecture incorporates dual-row 12-station tooling where each station operates independently, enabling flexible batch processing without cross-interference or downtime. Operators can easily adapt tooling fixtures to handle various cell heights, providing versatile support across diverse supercapacitor form factors and custom cell designs.

Engineered with an uncompromising focus on corrosion resistance and operational longevity, the entire fluid path and mechanical framework utilize premium 316 stainless steel, high-purity industrial ceramics (zirconia and alumina), PTFE, and 6-series aluminum alloy. Advanced multi-stage vapor filtration and mechanical positioning systems replace fragile optical and electronic components, ensuring continuous, drift-free operation under corrosive organic and acidic electrolyte chemistries.

Key Features

• Valveless Precision Ceramic Metering Pumps: Dual high-purity zirconia (ZrO₂) and alumina (Al₂O₃) ceramic pumps utilize gel-casting nanotechnology to achieve exceptional microstructural density, self-lubrication, and self-sealing performance without dynamic soft seals or lubricant contamination.
• High Dispensing Accuracy & Wide Range: Delivers an injection accuracy of ±1% across an adjustable volume range of 0 to 250 mL, backed by a high-torque pump drive capable of discharge flow rates up to 40 mL/s without stalling or crystallization seizure.
• Programmable Vacuum & Pressure Cycling: Automatically executes sequential vacuum pre-evacuation (≥ -98 kPa), precision electrolyte dosing, and alternating vacuum-pressurization standing routines to accelerate separator saturation and eliminate micro-bubbles.
• Bi-Directional Pumping & Anti-Crystallization Suction: Features forward dispensing and reverse suction modes that allow complete evacuation of residual electrolyte back into the transfer reservoir during idle periods, preventing line clogging and crystallization.
• Corrosion-Proof Mechanical Positioning: Rugged stainless steel mechanical positioning mechanisms replace vulnerable optical and electronic sensors inside the glovebox, eliminating electrolyte-induced sensor failures and tedious maintenance downtime.
• Automated Buffer Reservoir Management: Integrated electrolyte intermediate tank features automated high- and low-level monitoring to trigger self-refilling cycles, preventing dry running and ensuring uninterrupted high-throughput production.
• Multi-Stage Vapor Filtration & Pump Protection: Advanced multi-tier particulate filtration and specialized chemical absorption systems trap corrosive electrolyte vapors, keeping pneumatic lines clear and protecting external vacuum pumps from chemical corrosion.
• Independent 12-Station Modular Operation: Dual-row 12-station layout driven by dual precision leadscrews allows single-cell injection or partial batch runs without requiring all stations to be loaded, maximizing operational flexibility.
• Heavy-Duty Chemical-Resistant Construction: Built with an anodized 6-series aluminum frame, SUS304/SUS316 stainless steel fluid contacts, and chemical-resistant PE and PTFE tubing to withstand harsh acidic, alkaline, and organic electrolyte vapors.
• Integrated High-Precision Gravimetric QC: Includes an industrial weighing balance and dedicated computer interface to log pre-fill and post-fill cell weights, enabling real-time statistical process control and 100% quality verification.
