4 FAQs about System resistance of flow battery

What is a flow battery?

Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection.

How does electrolyte resistance affect a membraneless single flow battery?

For membraneless single flow battery designs, electrolyte resistance is the leading contributor to overall battery resistance, , which directly impacts the power output .

What is the difference between power and power in flow batteries?

The key differentiating factor of flow batteries is that the power and energy components are separate and can be scaled independently. The capacity is a function of the amount of electrolyte and concentration of the active ions, whereas the power is primarily a function of electrode area within the cell.

What are the components of a flow battery?
