  9. History

A flow battery, or redox flow battery, is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane. A flow battery may be used like a rechargeable battery, where an electric power source drives regeneration of the fuel. Advantages over conventional rechargeables includes separable liquid tanks and near unlimited longevity. Current disadvantages are comparatively less power and a need for more sophisticated electronics. Flow batteries are normally considered for relatively large (1 kWh – 10 MWh) stationary applications, including: load balancing, storing energy from renewable sources, peak shaving, UPS, power conversion, electric vehicles and stand-alone power system.
