Carbon materials demonstrate suitable physical and chemical properties for applications in bromine based redox flow batteries (RFBs). This review summarizes the bromine/bromide reaction mechanisms taking place at the carbon electrode and provides an overview of different carbon based materials as the bromine electrodes.
Bromine-based flow batteries (Br-FBs) have been widely used for stationary energy storage benefiting from their high positive potential, high solubility and low cost. However, they are still confronted with serious challenges including bromine cross-diffusion, sluggish reaction kinetics of Br 2 /Br − redox couple and sometimes dendrites.
Bromine based redox flow batteries (RFBs) can provide sustainable energy storage due to the abundance of bromine. Such devices pair Br 2 /Br − at the positive electrode with complementary redox couples at the negative electrode. Due to the highly corrosive nature of bromine, electrode materials need to be corrosion resistant and durable.
Among various FBs, bromine-based flow batteries (Br-FBs) using Br 2 /Br − couple with high solubility and high potential as the positive active substance have attracted increasing attention, benefiting from their advantages of high energy density and low cost , .
