ARE REDOX FLOW BATTERIES SUITABLE FOR GRID ENERGY STORAGE

Main issues of liquid flow batteries for energy storage

Some of the main issues are as follows: (i) a gradual but continuous loss in capacity retention upon cycling (cycle life), which is exacerbated if the batteries at any point during their operation become completely or close to completely discharged, hence the need for a protection to avoid full depletion, (ii) a limited shelf-life (calendar life), even when the batteries are not being used, and, (iii) finally, prolonged exposure to heat reduces the battery lifetime.
