It is where electrochemical reactions occur between two electrolytes, converting chemical energy into electrical energy.
What is a flow battery?
A flow battery is a type of electrochemical energy storage (ES) that consists of two chemical components dissolved in liquid, separated by a membrane. Flow batteries work by transferring ions from one component to another through the membrane during charging and discharging.
Can a flow battery be modeled?
MIT researchers have demonstrated a modeling framework that can help model flow batteries. Their work focuses on this electrochemical cell, which looks promising for grid-scale energy storage—except for one problem: Current flow batteries rely on vanadium, an energy-storage material that’s expensive and not always readily available.
What is a hybrid flow battery?
A hybrid flow battery is similar to typical batteries, but with a key difference. It is limited in energy by the size of the battery electrode, i.e., the reactor size. Energy producing electrochemical cells are generally divided into two categories.
