Vacuum Electrolyte Filling And Standing Integrated Machine For Battery Capacitor Cells

Product Overview

This vacuum electrolyte filling and standing integrated machine combines two critical battery and capacitor processes in one controlled platform: electrolyte filling and post-filling standing. The process follows a vacuum-first sequence, removing air before electrolyte introduction and then maintaining the programmed standing condition. This improves electrolyte penetration, filling consistency, and process reliability while reducing manual intervention.

The equipment is designed for pouch and other compatible cell formats used in battery research, capacitor development, pilot production, and advanced materials laboratories. Adjustable filling volume, dispensing speed, vacuum level, pressure-holding condition, and standing time allow operators to adapt the process to different cell designs and electrolyte requirements.

A rigid structure, corrosion-resistant wetted components, transparent observation window, guided pneumatic chamber movement, and PLC touchscreen control support dependable operation in demanding laboratory and pilot-scale environments. The unit can be operated inside a glovebox or dry room, making it suitable for moisture-sensitive cell fabrication workflows.

Key Features

• Integrated Filling and Standing Functions: One system performs electrolyte dispensing and controlled standing, reducing handling steps, equipment transfers, and opportunities for process variation.

• Vacuum-First Process Sequence: The chamber is evacuated before electrolyte filling, supporting improved electrolyte absorption and more consistent wetting of the cell interior.

• High Dosing Precision: Adjustable pump control provides an electrolyte filling accuracy of ±1%, helping laboratories maintain repeatable cell-to-cell process conditions.

• Flexible Process Parameters: Filling speed, filling quantity, vacuum level, pressure-holding condition, and standing time can be adjusted to match different cell structures and research protocols.

• Extended Time Programming: Low or high vacuum levels and standing durations can be configured independently, with each time setting adjustable up to 9999 minutes for long-duration soaking and stabilization procedures.

• Corrosion-Resistant Construction: Critical components use stainless steel 304 and 316 materials, while the vacuum chamber is manufactured from welded aluminum for structural stability and corrosion resistance.

• Controlled Chamber Movement: A pneumatic cylinder drives the chamber cover, while a rotating guide sleeve provides accurate guidance. Smooth vertical movement helps maintain reliable sealing during repeated operation.

• Process Visibility: A transparent observation window allows operators to monitor changes inside the chamber while the process is running, improving operational awareness without interrupting the cycle.

• Chemical-Resistant Connections: The inlet and outlet lines use chemically resistant flexible tubing, supporting safer electrolyte handling and more durable fluid connections.

• PLC Touchscreen Automation: PLC-based control with touchscreen operation enables flexible parameter programming, straightforward adjustment, and a high level of process automation.

Applications

Technical Specifications

The dimensional range accommodates cells from 20 to 200 mm in length, including tabs, with widths from 20 to 200 mm including the gas-bag position. Cell thickness can range from 0 to 15 mm. This makes the equipment suitable for a broad selection of laboratory pouch-cell and capacitor formats, provided the workpiece remains within the stated envelope.

The filling system is designed for flexible capacity adjustment through the selected pump configuration. Both volumetric filling quantity and electrolyte filling mass begin at 0.2 units and can be extended to unlimited capacity according to pump adjustment. The specified dispensing speed reaches 6 mL/s and remains adjustable, allowing operators to balance throughput, wetting behavior, and process sensitivity.

Vacuum and standing conditions can be tailored to the material system and cell construction. Low or high vacuum settings are adjustable, while each programmed time can reach 9999 minutes. Filling speed, filling amount, vacuum degree, pressure-holding condition, and standing duration can all be configured through the control interface. This flexibility is useful for short process cycles as well as extended absorption and stabilization studies.

Mechanical design focuses on repeatable sealing and stable operation. The chamber cover moves vertically through a pneumatic cylinder and is guided by a rotating guide sleeve. Accurate guidance helps the cover move smoothly and supports the sealing performance required for vacuum processing. A transparent window gives the operator direct visibility into chamber changes during a cycle, supporting faster confirmation of process behavior.

Material selection is aligned with electrolyte-handling requirements. Stainless steel 304 and 316 are used at critical locations for corrosion resistance, while the vacuum chamber uses welded aluminum to combine structural stability with resistance to the operating environment. The Φ6 inlet and outlet tubing provides a defined connection size for electrolyte delivery and discharge routing.

The compact footprint measures 510 mm in length, 400 mm in width, and 650 mm in height. With an AC220V, 50Hz, 1 kW power supply, the unit can be integrated into laboratory workstations, glovebox environments, or dry-room process areas where space and utility access must be managed carefully. PLC and touchscreen control provide a practical interface for setting and repeating process recipes.
