Six Station Vacuum Electrolyte Filling Machine for Supercapacitor Batteries

Product Overview

This six-station vacuum electrolyte filling machine is designed for the electrolyte filling stage of supercapacitor and cylindrical battery production. It uses a controlled sequence of high-vacuum extraction, electrolyte filling, low-vacuum treatment, pressurization, and pressure release to improve electrolyte absorption uniformity, completeness, and repeatability. Filling volume, vacuum timing, pressure timing, standing time, and cycle parameters can be adjusted to match different process requirements.

The system is intended for 60-series batteries and supercapacitors with product heights from 50 to 204 mm. It is suitable for laboratory development, pilot-scale manufacturing, and specialized production lines where stable electrolyte dosing and controlled impregnation are essential. The six workstations can be operated independently, allowing flexible loading, unloading, and process management without mutual interference.

Because supercapacitor electrolytes can be highly corrosive and prone to crystallization, the equipment is engineered for demanding chemical exposure. Corrosion-resistant flow-path materials, multi-stage filtration, adsorption protection, and accessible service layouts help maintain reliable operation while reducing contamination, blockage, vacuum-pump damage, and unnecessary glovebox purification cycles.

Key Features

• Vacuum First Filling Process: The unit extracts high vacuum before filling, then alternates low vacuum and pressurization during the standing stage. This process promotes more complete electrolyte penetration and consistent absorption within the product.

• Six Independent Workstations: Six products can be processed in one cycle, with each station independently selectable and operable. This arrangement supports flexible production scheduling, staged loading, and efficient handling of development samples or small batches.

• High Filling Accuracy: Electrolyte dosing accuracy is specified at ±1%, helping control electrolyte content and improve batch-to-batch consistency in supercapacitor and battery manufacturing.

• Adjustable Process Parameters: Vacuum time, high-vacuum value, low-vacuum value, filling volume, standing time, pressurization pressure, pressure duration, and pressure-release time can be configured according to product and process requirements.

• Corrosion-Resistant Fluid Path: Stainless steel tank connections, corrosion-resistant PE hoses, and SUS316 and PTFE components in the special dual-path pneumatic valves provide strong resistance to aggressive electrolyte exposure and crystallization conditions.

• Anti-Blockage Protection: Multi-stage filtration and a dedicated adsorption system help keep valves and pipelines clear while protecting the vacuum pump from corrosive vapor, crystallized residue, and particles that could damage or block pump components.

• Reduced Glovebox Exposure: Electrolyte exposure inside the glovebox is minimized during filling, reducing vapor contact with other glovebox components and helping limit corrosion of surrounding equipment.

• Accessible Cleaning and Maintenance: The internal filtration and pipeline layout is positioned for convenient operator access. Filters can be removed easily, accumulated liquid can be discharged, and blocked tubing can be cleared through the glovebox operating port without removing the glovebox glass.

• DMC Cleaning Function: Integrated DMC cleaning capability supports scheduled monthly or quarterly maintenance, helping keep the fluid path clean and reducing the frequency of extensive manual cleaning operations.

• Adaptable Product Fixturing: The fixture can be removed and installed conveniently to accommodate products with different heights. Other product sizes can also be customized according to application requirements.

Applications

Technical Specifications

The process architecture is designed to address the specific operating challenges created by corrosive and crystallizing supercapacitor electrolytes. The fluid path, valve assemblies, filtration components, and adsorption protection system have been repeatedly optimized through practical supercapacitor filling applications. This engineering focus helps reduce the risk of blocked valves, restricted tubing, failed vacuum extraction, and unplanned maintenance.

The equipment is configured for operation with a glovebox nitrogen environment. The gas requirement is specified at a minimum pressure of 0.4 MPa, with consumption of 0.2 m³/min. The vacuum source is not included in the listed equipment configuration and must be provided by the customer, either through a suitable vacuum pump or a vacuum pipeline capable of maintaining pressure above -98 KPa. Installation teams should confirm the available utilities before commissioning.

The physical installation envelope should also be assessed during project planning. The workstation measures 900 mm long, 450 mm wide, and 870 mm high, while the control box measures 600 mm long, 450 mm wide, and 1500 mm high. The combined gross weight is 330 kg, and the installation floor must support more than 0.3 T/m². For upper-floor placement, the transport elevator should provide at least 1 m width, 2 m height, and 1.3 m depth. The complete搬运 route from outside the facility to the workshop and the final installation method should be confirmed before shipment.

Why Choose This Product

• Engineered for Difficult Electrolytes: The corrosion-resistant construction and anti-crystallization flow-path design address the failure modes most commonly associated with aggressive supercapacitor electrolytes.

• Consistent Production Control: ±1% filling accuracy, adjustable process parameters, and repeatable vacuum-pressure cycling support stable electrolyte loading across development and production batches.

• Lower Maintenance Burden: Accessible filters, convenient residual-liquid discharge, DMC cleaning capability, and glovebox-side service access simplify routine cleaning and reduce avoidable downtime.

• Premium Structural Materials: Stainless steel connections, SUS316 and PTFE valve components, corrosion-resistant PE hoses, and a 6-series aluminum alloy body provide a durable foundation for long-term operation.

• Application Flexibility: Six independent stations, adjustable fixtures, and support for product heights from 50 to 204 mm make the equipment suitable for changing research, pilot, and manufacturing requirements.
