Title:
METHOD FOR PREPARING VANADIUM-BASED ELECTROLYTE SOLUTION
Document Type and Number:
WIPO Patent Application WO/2024/025323
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a vanadium-based electrolyte solution. Specifically, the present invention relates to a method for preparing a vanadium electrolyte solution for a vanadium flow battery. In the method for preparing a vanadium-based electrolyte solution, of the present invention, an organic reducing agent such as oxalic acid does not remain. The method for preparing a vanadium-based electrolyte solution, of the present invention, enables a high-quality 3.5-valent vanadium electrolyte solution to be simply prepared. The method for preparing a vanadium-based electrolyte solution, of the present invention, enables a 3.5-valent vanadium electrolyte solution to be mass-produced.
