Abstract
As a kind of emerging energy storage measure, the vanadium flow battery utilizes the ion exchange of vanadium ions to store and discharge energy. Among the existing energy storage technologies, it has high potential and significance due to its several advantages. However, there are still aspects that can be improved and promoted: in battery diaphragm, the voltage and current efficiency could be improved by modifying the ion permeability; The cost of electrolyte is high which can still optimize by selecting low-cost material, through mixing the electrolyte, the cycle life can be extended as well as enable the discharge capacity regeneration; Electrode has the problem of corrosion that affects the lifetime of an electrode, meanwhile, reduce the battery efficiency. In this article, the research progress of vanadium flow battery and the defective aspects of it is investigated, and based on the available cases, the possible solutions and suggestions for the existing problems in battery cells, electrolytes, and electrodes are analyzed. At last, the overall prospect of the vanadium flow battery itself is also discussed.
