Flow Battery
A flow battery is a type of rechargeable battery that stores electrical energy in two tanks of electrolytes. When operators need energy, they pump liquid from one tank to another.
As a result, this process allows flow batteries to provide a reliable and efficient energy storage solution. Also Read: How Solid State Batteries are Made from Start to Finish Flow Batteries offer remarkable scalability and flexibility. I find their modular design particularly beneficial.
The liquid contained in the flow battery contains active ions that will flow through the electrochemical cell. The way flow batteries store energy reserves is different from other types of batteries such as lithium-ion which stores energy in solid electrodes (find out how do lithium-ion batteries work to understand it further).
You might believe that flow batteries are a new technology merely invented over the past few years. Actually, the development of flow batteries can be traced back to the 1970s when Lawrence Thaller at NASA created the first prototype of this battery type.
Flow batteries can be classified using different schemes: 1) Full-flow (where all reagents are in fluid phases: gases, liquids, or liquid solutions), such as vanadium redox flow battery vs semi-flow, where one or more electroactive phases are solid, such as zinc-bromine battery.
