Vanadium battery is a kind of liquid flow battery with vanadium ion solution as active material and electrolyte. Vanadium electrolyte is also one of the core materials of the whole battery. Its production technology and production cost largely determine the cost of vanadium battery.

Technical parameters:

1. Electrolyte concentration: ≥ 2mol / L

2. Electrolyte storage capacity: 25wh / L (watt hour / liter).

3. Temperature ≤ 60 ° C, no high valence vanadium crystal released

4. Preparation directly from vanadium pentoxide

5. Temperature ≥ 0 ° C, vanadium free crystal precipitates due to low temperature; If precipitation occurs due to low temperature, it can be eliminated and recovered by heating

6. Sulfuric acid concentration: 3mol / L
