Title:
ELECTROLYTE SOLUTION AND REDOX FLOW BATTERY
Document Type and Number:
Japanese Patent JP2021028866
Kind Code:
A
Abstract:
To provide an electrolyte solution which can suppress the decrease in electric capacity owing to crossover, and a redox flow battery including the electrolyte solution.SOLUTION: The decrease in the electric capacity of a redox flow battery, which is caused by crossover, can be suppressed by using an electrolyte solution containing alkali-metal ions and vanadium ions in the redox flow battery. The alkali-metal ions are at least one kind of ions selected from lithium ions, sodium ions, potassium ions, rubidium ions and cesium ions. The total concentration of the alkali-metal ions is 0.3 M to 2.0 M, preferably 0.3 M to 1.5 M, and more preferably 0.3 M to 1.0 M.SELECTED DRAWING: None
