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 adsorption system to keep valves and pipelines unobstructed
Ultra-high metering precision and superior repeat consistency
Pre-vacuum before injection; alternating vacuum & pressure soaking cycles for high efficiency, precise dosing and stable operation
Fully adjustable process parameters: vacuum duration, high/low vacuum levels, filling volume, soaking time, pressurization duration & pressure relief time
Compatible with glove box and dry room operation
Valve-free construction delivers ultra-stable flow with high dosing accuracy
Forward & reverse suction functions via reciprocating rotary operation
Bubble-free, leak-free, drip-free and clog-free fluid delivery with zero waste
Low maintenance design: only plunger rod as moving part; no dynamic seals or vulnerable consumables
