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.
There are different types of flow batteries. The main types are reduction-oxidation (redox) flow batteries, membraneless flow batteries, organic flow batteries, and hybrid flow batteries. Below we explain in more detail the common main types: The most common flow battery type is the redox flow battery, or also called: true redox flow battery.
Lithium-ion batteries with flow systems. Commercial LIBs consist of cylindrical, prismatic and pouch configurations, in which energy is stored within a limited space 3. Accordingly, to effectively increase energy-storage capacity, conventional LIBs have been combined with flow batteries.
The key differentiating factor of flow batteries is that the power and energy components are separate and can be scaled independently. 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.
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.
