How do flow batteries work?
Flow batteries operate distinctively from “solid” batteries (e.g., lead and lithium) in that a flow battery's energy is stored in the liquid electrolytes that are pumped through the battery system (see image above) while a solid-state battery stores its energy in solid electrodes. There are several components that make up a flow battery system:
