Technical FAQs 4

How efficient is a flow battery?

This flow battery also demonstrates 81% of capacity for 100 cycles over ~45 days with average Coulombic efficiency of 96% and energy efficiency of 82% at the current density of 1.5 mA/cm2 and at a temperature of 27 °C.

What are the key measures of a flow battery?

The focus in this research is on summarizing some of the leading key measures of the flow battery, including state of charge (SoC), efficiencies of operation, including Coulombic efficiency, energy efficiency, and voltage efficiency, and energy density.

How does flow factor affect battery efficiency?

Linking with Eq. 22, the higher the current, the greater the flow rate needed; therefore, the pressure losses will increase, implying a higher need for pump power. This probably directly limits the value of the flow factor. Knowing the optimum flow factor for battery operation is of great interest to optimize battery efficiency.

What is the energy density of a flow battery?

The flow battery exhibits a high cell voltage of 3.53 V, resulting in a high energy density of approximately 33 Wh/L. Pre- and post-cycling battery analysis confirmed the absence of crossover of the active materials. Fig. 1: Chemical formulas and redox voltages of organic redox materials.
