Vacuum Electrolyte Filling Standing and Pre Sealing All in One Machine for Pouch Cell and Supercapacitor Assembly

Product Overview

This integrated system combines precision vacuum electrolyte filling, vacuum standing diffusion, and hot-press pre-sealing into a single compact footprint. Designed specifically for advanced lithium-ion pouch cell and supercapacitor manufacturing, the equipment optimizes the wetting and pre-packaging workflow. By drawing high vacuum prior to liquid injection, the system ensures rapid, uniform electrolyte dispersion throughout dense electrode matrices, significantly reducing soaking cycles while eliminating gas entrapment and dry spots.

Engineered for research laboratories, pilot-scale fabrication lines, and specialty energy storage manufacturing, this all-in-one workstation interfaces seamlessly with argon-filled gloveboxes or dry room environments. It provides full recipe management through an intelligent programmable logic controller (PLC) and touchscreen interface. Operators can process pouch cells and ultracapacitors with precise dosage calibration, stable chamber evacuation, and uniform thermal pre-sealing without transferring sensitive, unsealed cells across multiple standalone stations.

Constructed with heavy-duty aluminum vacuum chambers and chemical-resistant 304 and 316 stainless steel wetted components, the equipment demonstrates exceptional structural integrity and corrosion resistance against aggressive battery electrolytes. Dual linear guide bushings and highly conductive copper sealing jaws guarantee repeatable thermal contact and tight mechanical parallelism across every run, providing unmatched process consistency, minimal maintenance overhead, and superior production yields.

Key Features

• Three-in-One Integrated Workflow: Combines vacuum electrolyte injection, vacuum standing and wetting diffusion, and thermal pre-sealing inside a single processing environment, minimizing cell transfer risks and volatile solvent exposure.
• Pre-Vacuum Injection Architecture: Evacuates the chamber prior to high-precision liquid dispensing, facilitating instantaneous electrolyte penetration into porous separators and thick electrode coatings with ±1% dosing accuracy.
• High-Conductivity Copper Sealing Jaws: Employs rapid-thermal-response copper alloy heating bars to deliver uniform heat transfer, lowering overall electrical consumption while preventing localized thermal degradation of pouch laminate materials.
• Dual Linear Guide Alignment: Features cylinder-driven upper sealing jaws guided by precision-ground dual linear guide bushings, maintaining parallel contact and guaranteeing that seal thickness variation across any two points remains under 15 µm.
• Corrosion-Resistant Fluid Circuitry: Utilizes industrial-grade fluoropolymer and chemical-resistant delivery tubing paired with 304/316 stainless steel internal hardware to resist degradation from corrosive lithium salts, organic carbonates, and ionic liquids.
• Broad Dimensional Versatility: Accommodates diverse cell configurations ranging from 20 mm × 20 mm up to 190 mm × 190 mm with thickness allowances up to 15 mm, supporting flexible R&D across pouch batteries and supercapacitors.
• Wide-Range Precision Dosing: Supports injection volumes from 0.2 ml up to 3 L (0.2 g to 3 kg) with an adjustable dispensing velocity up to 6 ml/s, allowing rapid adaptation between thin laboratory prototypes and high-capacity cells.
• Integrated Large Inspection Window: Integrates an optically clear, high-vacuum sight glass into the chamber wall, granting real-time visual monitoring of electrolyte dispensing, bubble elimination, and mechanical jaw actuation.
• Glovebox and Dry Room Compatibility: Designed with a compact profile, sealed pass-through compatibility, and hermetic construction, making the unit ideal for installation inside inert atmosphere gloveboxes or low-dew-point dry rooms.
• Advanced PLC and Touchscreen Interface: Provides intuitive digital parameter control over vacuum levels, standing durations, injection speeds, sealing temperatures up to 250°C, sealing pressures, and dwell times with multi-recipe storage.
