Flow batteries (FBs) are widely regarded as one of the most promising energy storage technologies owing to their advantages of high safety, environmental friendliness, and long cycle life , , .
Requirements of electrolytes In a flow battery, the electrolytes serve as the working solution carrying redox active substances, some vital parameters such as open circuit voltage (OCV), conductivity, viscosity, concentration, etc. will have great impacts on the battery.
The anolyte and catholyte solutions are stored in separate tanks, which allows the energy capacity of the flow battery to be scaled independently of the power capacity that is determined by the size of the flow battery .
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
High concentration MnCl 2 electrolyte is applied in manganese-based flow batteries first time. Amino acid additives promote the reversible Mn 2+ /MnO 2 reaction without Cl 2. In-depth research on the impact mechanism at the molecular level. The energy density of manganese-based flow batteries was expected to reach 176.88 Wh L -1.
It also contains two electrolyte solutions, called the anolyte and the catholyte, which undergo reversible redox reactions . The anolyte and catholyte solutions are pumped into the flow battery .
