Vacuum Electrolyte Injection Standing and Hot Press Pre Sealing All in One Machine for Battery and Supercapacitor Fabrication

Product Overview

This all-in-one workstation integrates precision vacuum electrolyte injection, programmable vacuum soaking, and hot press pre-sealing into a single compact benchtop architecture. Engineered specifically for pouch cell and supercapacitor assembly, the system executes an automated workflow: pulling a high vacuum, dispensing electrolyte with high volumetric accuracy, facilitating thorough active-material wetting during an adjustable standing phase, and hermetically pre-sealing the cell casing under controlled thermal and pneumatic pressure. By consolidating three critical cell-finishing steps into one continuous cycle, this equipment eliminates cell handling between distinct stations and prevents atmosphere exposure during critical wetting phases.

Designed for battery prototyping laboratories, advanced energy research institutes, and pilot-scale production lines, this processing system delivers superior process repeatability across diverse chemistries. It accommodates standard lithium-ion pouch cells, emerging sodium-ion configurations, solid-state electrolyte formulations, and electrical double-layer capacitors. Its compact footprint and gas-tight design make it directly deployable within argon-filled gloveboxes or standard dry room environments without compromising cleanroom workspace.

Constructed from industrial-grade corrosion-resistant alloys, the unit withstands aggressive organic solvents, fluorinated lithium salts, and harsh electrolyte vapors. High-grade linear guides and precision pneumatic actuators ensure uniform mechanical pressure across the entire sealing plane, guaranteeing that cell batches exhibit consistent seal thickness, minimal electrolyte leakage, and uniform electrochemical performance during subsequent formation and cycling testing.

Key Features

• Integrated 3-in-1 Processing Workflow: Combines vacuum liquid dosing, prolonged standing/soaking, and thermal edge pre-sealing into one unified chamber, maximizing laboratory space efficiency while drastically shortening cycle times.
• Ultra-Precise Volumetric Dosing: High-accuracy fluidic pump mechanism achieves ±1% injection accuracy with a flexible dispensing volume starting from 0.2 ml to continuous flow, ensuring consistent electrolyte-to-capacity ratios across cell batches.
• Dual-Stage Vacuum and Programmable Standing: Features independently adjustable low- and high-vacuum parameters with soak timers programmable up to 9999 minutes to guarantee deep electrolyte penetration and pore saturation in dense electrode matrices.
• High-Conductivity Copper Sealing Bars: Thermal sealing heads are machined from high-grade solid copper alloy, delivering rapid thermal response, uniform temperature distribution up to 250°C, and lower electrical power consumption compared to conventional steel tooling.
• Precision Linear Guide Parallelism: Upper and lower sealing dies are driven by pneumatic cylinders guided by dual linear bushings, maintaining strict die parallelism and yielding total sealing thickness tolerances under 15 µm across the entire 200 mm sealing edge.
• Intelligent PLC and Touchscreen Control: An industrial programmable logic controller coupled with an intuitive digital touchscreen provides real-time monitoring and recipe storage for vacuum levels, temperatures, dwell times, and pneumatic pressing forces.
• Superior Chemical and Corrosion Resistance: Fluid contact pathways, internal fasteners, and structural hardware are fabricated from premium AISI 304 and 316 stainless steel, coupled with chemically resistant flexible tubing and a welded aluminum vacuum vessel.
• Wide-Angle Optical Inspection Window: High-clarity viewport integrated into the vacuum chamber allows operators to visually monitor electrolyte dispensing dynamics, wetting progression, and sealing mechanics without disrupting internal atmospheric conditions.
• Pneumatic Chamber Actuation with Guided Pivot: Vacuum chamber lid is driven by dedicated pneumatic cylinders with rotating guide bushings, ensuring effortless opening, repeatable closure alignment, and robust seal integrity over thousands of continuous cycles.
• Universal Glovebox and Dry Room Compatibility: Hermetic exterior architecture and compact benchtop dimensions allow seamless pass-through transfer and continuous operation inside ultra-low dewpoint dry rooms and inert gas glovebox environments.
