How do flow batteries work?
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 Reactions occur atthe electrodes Electrodes do not undergo a physical change Source: EPRI
What is the difference between power and capacity of a flow battery?
The capacity is a function of the amount of electrolyte and concentration of the active ions, whereas the power is primarily a function of electrode area within the cell. Similar to lithium-ion cells, flow battery cells can be stacked in series to meet voltage requirements. However, the electrolyte tanks remain external to the system.
What are the components of a flow battery?
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)
Where is electrolyte stored in a battery?
In a battery without bulk flow of the electrolyte, the electro-active material is stored internally in the electrodes. However, for flow batteries, the energy component is dissolved in the electrolyte itself. The electrolyte is stored in external tanks, usually one corresponding to the negative electrode and one to the positive electrode.
How do flow batteries maintain charge neutrality?
The charge neutrality condition for the each half-cell is maintained by a selective ion exchange membrane separating the anode and cathode compartments. The key differentiating factor of flow batteries is that the power and energy components are separate and can be scaled independently.
Can flow battery cells be stacked in series?
Similar to lithium-ion cells, flow battery cells can be stacked in series to meet voltage requirements. However, the electrolyte tanks remain external to the system. To optimize the efficiency of the cell, we can consider several related efficiencies, namely voltage efficiency, charge efficiency, power efficiency, and energy efficiency:
