What is a flow battery?
Battery geeks refer to the latter feature as a shallow “depth of discharge”. Flow batteries are a new entrant into the battery storage market, aimed at large-scale energy storage applications. This storage technology has been in research and development for several decades, though is now starting to gain some real-world use.
What is the difference between a flow battery and a rechargeable battery?
The main difference between flow batteries and other rechargeable battery types is that the aqueous electrolyte solution usually found in other batteries is not stored in the cells around the positive electrode and negative electrode. Instead, the active materials are stored in exterior tanks and pumped toward a flow cell membrane and power stack.
How long does a flow battery last?
Flow batteries can discharge up to 10 hours at a stretch, whereas most other commercial battery types are designed to discharge for one or two hours at a time. The role of flow batteries in utility applications is foreseen mostly as a buffer between the available energy from the electric grid and difficult-to-predict electricity demands.
Are flow batteries safer than lithium ion batteries?
Flow batteries are generally considered safer than lithium-ion batteries. The risk of thermal runaway is low, and they are less prone to catching fire or exploding.
