Title:
PHENAZINE-BASED COMPOUND, ELECTROLYTIC LIQUID COMPRISING SAME FOR REDOX FLOW BATTERY, AND REDOX FLOW BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/111725
Kind Code:
A1
Abstract:
The present invention relates to: a phenazine-based compound having a particular substituent; an electrolytic liquid comprising same for a redox flow battery; and a redox flow battery. The phenazine-based compound is a multi-redox organic substance capable of inducing a two-stage reversible redox reaction and shows high solubility in a non-aqueous solvent. Thus, the employment of the phenazine-based compound can provide an electrolytic liquid for a redox flow battery, capable of expressing high energy density, and a redox flow battery.
