K. Webb ESE 471 3 Flow Batteries Flow batteries are electrochemical cells, in which the reacting substances are stored in electrolyte solutions external to the battery cell Electrolytes are pumped through the cells Electrolytes flow across the electrodes
Flow batteries comprise two components: Electrochemical cell Conversion between chemical and electrical energy External electrolyte storage tanks Energy storage Source: EPRI K. Webb ESE 471 5 Flow Battery Electrochemical Cell Electrochemical cell Two half-cellsseparated by a proton-exchange membrane(PEM)
In contrast, the capacity of a flow battery can be simply increased by increasing the size of the external storage tanks of the electro-active materials. A flow battery is an electrochemical device that converts the chemical energy of the electro-active materials directly to electrical energy, similar to a conventional battery and fuel cell.
Flow batteries require electrolyte to be pumped through the cell stack Pumps require power Pump power affects efficiency Need a fluid model for the battery in order to understand how mechanical losses affect efficiency K. Webb ESE 471 29 RFB Fluid Model Power required to pump electrolyte through cell stack Pumping power is proportional to
