Automatic In Line Prismatic Battery Electrolyte Filling Machine for Pilot Line

Product Overview

This automatic in-line prismatic cell electrolyte filling machine provides high-precision quantitative dispensing and vacuum-assisted electrolyte absorption for aluminum-shell power batteries. Built specifically to bridge the gap between benchtop battery research and high-volume manufacturing, this system automates clamping, precision vacuuming, metering, and pressure cycling to achieve uniform electrolyte saturation across the electrode matrix.

Designed primarily for battery pilot lines, commercial prototyping facilities, and advanced energy storage production environments, the equipment handles batch-style processing with minimal operator intervention. It accommodates standard and custom prismatic cell profiles, ensuring reliable electrolyte uptake in thick, high-energy-density electrode stacks without damaging delicate separator membranes or cell casing seals.

Constructed on a rigid industrial frame with chemical-resistant fluid paths, this unit delivers consistent ±3‰ injection accuracy and maintains an operational availability exceeding 95% under 24/7 continuous operation. Procurement teams and manufacturing engineers can depend on this system to eliminate electrolyte wetting bottlenecks, optimize first-pass yields, and deliver repeatable cell-to-cell electrochemical performance.

Key Features

• 12-Channel High-Precision Simultaneous Injection: The dispensing manifold integrates twelve individual precision metering heads that fill an entire batch simultaneously, drastically reducing cycle times while maintaining strict channel-to-channel volume consistency.
• Pre-Vacuum Liquid Absorption Technology: Utilizing a vacuum absorption method reaching -0.095 MPa before electrolyte introduction, the system eliminates internal micro-voids and trapped gas pockets to accelerate electrolyte penetration into deep electrode pores.
• Programmable Vacuum, Nitrogen, and Soak Cycling: The intuitive control architecture enables process engineers to program multi-stage pressure profiles, including custom vacuum levels, holding durations, nitrogen gas purges, and resting intervals to suit unique electrolyte viscosities.
• Ultra-Tight Dosing Tolerance (±3‰): Engineered for rigorous quality assurance, each dispensing head maintains ±3‰ volumetric accuracy verified across consecutive multi-cycle sampling runs, ensuring superior batch uniformity and eliminating overfill or underfill defects.
• High Operational Uptime (≥95%): Designed for heavy-duty pilot line shifts, the mechanical drives, pneumatic actuators, and fluid-handling assemblies are rated for continuous 24-hour manufacturing with minimal maintenance downtime.
• Single-Operator Ergonomic Fixturing: The machine features a quick-clamp tooling carriage designed for single-operator manual loading and unloading, featuring automatic pneumatic positioning and secure clamping upon cycle initiation.
• Corrosion-Resistant Industrial Fluid Path: All wetted components, valves, and manifold lines are fabricated from high-grade stainless steel and specialized polymers resistant to corrosive lithium salts, organic carbonates, and additive chemistries.
• Integrated Safety and Enclosure Design: Heavy-duty sheet metal housing finished in high-durability industrial coatings shields operators, while safety interlocks and clear viewing windows provide comprehensive process visibility during vacuum and dispensing phases.
