Flow Battery
Redox Flow Batteries (RFBs) are rechargeable batteries that store and release energy through redox reactions occurring in liquid electrolytes. Unlike traditional batteries, RFBs separate energy capacity from power output, allowing for flexible scaling to meet specific needs. This makes them particularly suitable for large-scale energy storage systems.
The basic structure of an RFB includes storage tanks, a cell stack, and a fluid circulation system. The positive and negative electrolytes are stored in separate tanks and pumped into the cell stack, where redox reactions occur to either release or store energy. Key advantages of RFBs include adjustable capacity, long lifespan, and high safety due to the use of aqueous electrolytes. However, the initial setup costs can be high, and their energy density is lower compared to lithium-ion batteries, making RFBs more suitable for applications where space is not a constraint.
