Research progress of the shunt current in redox flow battery

The performance of large scale redox flow battery comprised with series cell models which are made up of parallel or series single cells was reduced by the shunt current,and the reason for the shunt current was the electrolyte common to all series cells.The reason for the shunt current and the harm of the shunt current to the redox flow battery system was introduced in detail.The electrical analog module of the shunt current and the method to predict the shunt currents were reviewed,and,also discussed the solutions to suppress the shunt current.
