One common type of battery schematic diagram is the single cell diagram. This diagram represents a single battery cell and shows the positive and negative terminals, as well as the internal components such as electrodes and electrolytes. It also indicates the direction of current flow within the cell.
Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection.
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:
In contrast with conventional batteries, flow batteries store energy in the electrolyte solutions. Therefore, the power and energy ratings are independent, the storage capacity being determined by the quantity of electrolyte used and the power rating determined by the active area of the cell stack.
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.
Flow field designs used in flow batteries have interested many researchers and engineers since 2012. Zawodzinski’s group first reported a vanadium flow battery (VRB) with a membrane (PEM) fuel cells. Improved limiting current density and peak power density (multiple fields where electrolyte enters a long channel packed with a porous electrode.
