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. Advantages over conventional rechargeables includes separable liquid tanks and near unlimited longevity. Flow batteries applications include: load balancing, storing energy from renewable sources, peak shaving, UPS, power conversion, electric vehicles and stand-alone power systems.
