The main disadvantage of flow batteries is their more complicated system requirements of pumps, sensors, flow and power management, and secondary containment vessels, making them most suitable for large-scale storage applications. The cost of an energy-storage device is a major impediment to utility adoption.
Flow batteries, while offering advantages in terms of decoupled power and energy capacity, suffer from lower energy density due to limitations in the solubility of active materials and electrode capacity. The broad voltage windows of non-aqueous electrolytes in flow batteries can also impact their energy density.
Unlike some other types of batteries, flow batteries don't contain flammable electrolytes, which reduces the risk of fire or explosion. The design of flow battery storage systems allows for the storage tanks to be installed separately from the conducting cell membrane and power stack, further enhancing safety.
Flow batteries have a higher initial cost compared to other battery types due to their complex design, which includes separate tanks for storing electrolytes, pumps, plumbing, and control systems. Moreover, their relatively low charge and discharge rates necessitate the use of substantial quantities of materials.
Flow batteries are interesting energy storage devices that can be designed flexibly due to the possibility of decoupling of power and energy. The design process allows a battery to evolve as the user needs change. Unfortunately, conventional batteries do not provide such a possibility.
Batteries and flow batteries/fuel cells differ in two main aspects. First, in a battery, the electro-active materials are stored internally, and the electrodes at which the energy conversion reactions occur are themselves part of the electrochemical fuel. The characteristics of the negative and positive electrodes determine both the power density
