Title:
METHOD FOR PRODUCING VANADIUM SULFATE (III), METHOD FOR PRODUCING ELECTRODE PRECURSOR, AND METHOD FOR PRODUCING VANADIUM REDOX SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2018168012
Kind Code:
A
Abstract:
To provide a method for producing vanadium sulfate (III) that makes it possible to obtain hydrates by control of warming temperature and warming time and facilitates industrial production, a method for producing an electrode precursor containing vanadium sulfate (III), and a method for producing a vanadium redox secondary battery that produces an electrode using the vanadium sulfate (III).SOLUTION: The method includes mixing a tetravalent or pentavalent vanadium compound, a saccharide, and sulfuric acid to obtain a mixture (S1), and warming the mixture to produce vanadium sulfate (III) (S3).SELECTED DRAWING: Figure 1
