Electrochemical studies on Alizarin Red S as Negolyte for Redox Flow Battery: A Preliminary Study

Redox flow battery (RFB) has received tremendous attention as energy storage system coupled with renewable energy sources. In this paper, a low-cost alizarin red S (ARS) organic dye is proposed to serve as the active material for the negative electrode reaction for or- ganic redox flow batteries...
