SECTION 5: FLOW BATTERIES K. Webb ESE 471 2Flow Battery Overview 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 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
Volume of electrolyte in external tanks determines energy storage capacity Flow batteries can be tailored for an particular application Very fast response times- < 1 msec Time to switch between full-power charge and full-power discharge Typically limited by controls and power electronics Potentially very long discharge times
The structural design to achieve a sealing effect on the zinc–air battery Unlike the fully enclosed structure of other commercial batteries, the semi-open system of the zinc–air battery consists of air electrodes on one side that are exposed to air and air electrodes on the other side that are in contact with the electrolyte.
Energy conversion is carried out in electrochemical cells similar to fuel cells. Most redox-flow batteries have an energy density comparable to that of lead-acid batteries, but a significantly longer lifespan. In the electrochemical cell, electrolyte solutions flow through the half-cell compartments of the plus and minus pole.
