Document Type and Number:
WIPO Patent Application WO/2019/206121
Kind Code:
A1
Abstract:
The present invention relates to a manufacturing method and device of a flow battery electrolyte. The manufacturing method of a vanadium electrolyte comprises: employing an electrochemical method to reduce a tetravalent vanadium ion to a divalent vanadium ion; and reacting the divalent vanadium ion with a low cost, low purity higher-valence vanadium oxide to form a tetravalent vanadium ion. The invention provides a closed-loop production process for continuous production, can be operated easily, has low material costs and low energy consumption, does not directly consume power, and generates no additional chemical contaminants.
