        Market Definition

        A flow battery is a rechargeable battery in which the electrolyte flows through various electrochemical cells from one or more tanks. The electrochemical cells used in flow batteries can be electrically connected in series or parallel, determining the overall power of a flow battery system. Flow batteries are considered safer than most commonly used lithium-ion batteries as they are resistant to high temperatures and exhibit a longer operational life, making them suitable for storing and releasing renewable energy from solar and wind sources. The scalability of flow batteries, wherein the battery’s energy storage capacity can be increased by increasing the quantity of electrolytes stored in the tanks, is another advantage driving the demand for flow batteries in large-scale energy storage applications.
