Vacuum Electrolyte Filling Standing Pre Sealing Integrated Machine for Batteries and Capacitors

Product Overview

This integrated system combines vacuum electrolyte filling, standing, and thermal pre-sealing in one compact platform for battery and capacitor production. The process sequence evacuates the chamber before filling, supports controlled electrolyte delivery and standing, then applies adjustable heat and pressure for pre-sealing. This integrated workflow improves process continuity while reducing manual transfers between individual operations.

The equipment is designed for battery cells and capacitors with dimensions from 20–190 mm in length, 20–190 mm in width, and 0–15 mm in thickness. It supports electrolyte capacities from 0.2 ml to 3 L and filling quantities from 0.2 g to 3 kg, depending on the selected pump adjustment. The system is suitable for operation inside a glove box or dry room and supports demanding research, development, and small-scale production environments.

Precision metering, adjustable process parameters, corrosion-resistant wetted connections, and guided thermal sealing provide dependable operation across varied cell formats. The transparent viewing window allows operators to observe changes inside the chamber during operation, while PLC and touchscreen control make automated process management practical and repeatable.

Key Features

• Three-in-One Process Integration: Combines electrolyte filling, standing, and thermal pre-sealing in one unit, helping streamline battery and capacitor manufacturing workflows and reduce handling between process stages.

• Vacuum-First Filling Sequence: The system evacuates the chamber before electrolyte injection, supporting efficient filling, accurate dosing, and reliable electrolyte absorption consistency.

• High Metering Accuracy and Repeatability: Adjustable pump control supports electrolyte capacities from 0.2 ml to 3 L and filling quantities from 0.2 g to 3 kg, with filling accuracy maintained at ±1%.

• Adjustable Filling and Sealing Parameters: Filling speed can be adjusted up to 6 ml/s. Thermal sealing temperature, pressure, and dwell time can also be configured for different process requirements.

• Efficient Copper Sealing Head: The copper sealing head provides effective heat transfer, helping reduce heating energy consumption while supporting efficient thermal pre-sealing.

• Stable Guided Sealing Motion: A pneumatic cylinder drives the sealing head through two linear guide sleeves. This construction supports smooth movement, accurate guidance, and parallel sealing edges.

• Corrosion-Resistant Fluid Path: Inlet and outlet connections use chemically resistant hoses, while key structural areas use 304 and 316 stainless steel for improved resistance in electrolyte-processing environments.

• Durable Vacuum Chamber: The aluminum-welded vacuum chamber provides a corrosion-resistant and structurally stable enclosure for controlled filling and standing operations.

• Operator Visibility and Control: A transparent viewing window enables observation of chamber conditions during operation. PLC and touchscreen controls provide flexible parameter setting and automated program execution.

• Flexible Installation: The equipment can be operated inside a glove box or dry room, supporting moisture-sensitive battery and capacitor processing requirements.

Applications

Technical Specifications

The integrated process design is especially valuable where filling accuracy, electrolyte absorption consistency, and sealing uniformity must be maintained across repeated batches. The adjustable pump allows the filling range to be matched to the selected application, while the independently adjustable thermal parameters help accommodate different cell structures and process conditions.

The sealing mechanism is engineered for controlled movement rather than simple downward compression. The pneumatic drive and dual linear guide sleeves help maintain accurate alignment and parallelism during sealing. Together with the copper sealing head and adjustable pressure control, this arrangement supports consistent sealing edges and helps achieve a thickness difference below 15 μm between any two sealing points.

The electrical and mechanical configuration is suited to laboratory and pilot-scale environments. A 1 kW AC220 V / 50 Hz power supply supports the complete unit, while the 300 W heating tube provides thermal sealing capability with approximately 0.6 kW consumption during heating. The compact 600 mm × 620 mm × 800 mm footprint makes the system practical for installation in controlled research or production areas.

Why Choose This Product
