Scalability: One of the standout features of flow batteries is their inherent scalability. The energy storage capacity of a flow battery can be easily increased by adding larger tanks to store more electrolyte.

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.

What is the difference between flow batteries and lithium-ion batteries?

When comparing flow batteries to lithium-ion batteries, several key differences become apparent: Energy Density: Lithium-ion batteries have a higher energy density, meaning they can store more energy in a smaller space. However, this comes at the expense of longevity, as lithium-ion batteries tend to degrade over time.
