This machine is designed for electrolyte filling of lithium batteries and supercapacitors. It adopts a process of pre-vacuuming, electrolyte injection, then alternating vacuum & pressure soaking, delivering outstanding electrolyte absorption uniformity and operational reliability.
Key Features
- Multi-stage filtration & special adsorbent system to keep pipelines unobstructed and protect vacuum pumps from corrosion damage
- Built-in DMC solvent cleaning function for monthly & quarterly pipeline maintenance
- Anti-clog dual pneumatic valves; all wetted valve components made of SUS316 stainless steel and PTFE for superior chemical resistance
- Ultra-high metering precision and repeatability, dosing tolerance within ±1%
- Process flow: vacuum pumping prior to filling, followed by alternating vacuum & pressure soaking cycles for high efficiency, accurate dosing and stable operation
- Fully adjustable process parameters: vacuum duration, high/low vacuum levels, filling volume, soaking time, pressurization holding time and pressure relief time
- Corrosion-resistant long-service design with imported core components
- Tank fittings made of stainless steel; chemical-resistant PE fluid hoses for full machine corrosion resistance
- Quick-disassembly tooling fixtures for easy adaptation to cells of different heights
