JLB-10 Single-Head Electrolyte Filling Machine

Precision electrolyte dispensing for Li-ion cell assembly

The JLB-10 Single-Head Electrolyte Filling Machine is designed for repeatable, small-volume electrolyte dosing during lithium-ion cell assembly and R&D workflows. It uses a rotating, reciprocating positive-displacement injection pump with ceramic wetted components to deliver controlled micro-volumes with strong chemical compatibility for common Li-ion electrolytes.

Principle of operation

A stepper-motor-driven pump converts programmed rotation and stroke counts into precise volumetric displacement. Users set the target dose by adjusting the stroke number and operating speed, enabling consistent electrolyte injection into cells or fixtures. The controller provides stable control of pump motion to support repeatable filling across batches.

Key specifications and features

• Filling range: 0–2.4 mL (adjustable)
• Filling accuracy: within 3%
• Speed: 1–800 rpm (typical best range for battery work: 60–200 rpm)
• Stroke number: 1–9999 cycles
• Power input: AC 110/220 V, 50/60 Hz
• Compact layout: controller box and separate filling head for flexible integration
  
  

Compatibility and typical use cases

• Suitable for cylindrical and pouch cells, as well as lab fixtures for electrolyte dosing
• Commonly deployed in dry rooms or gloveboxes as part of an integrated cell-assembly line
• Supports research workflows such as electrolyte screening, formation studies, and process optimisation prior to scale-up
