Abstract: High power density and capacity energy storage technology for energy source structure adjustment and the utility of the renewable energy is in urgent need. Owning to the characteristics of separation of the energy and the power, high safety and long cycling life, the flow battery become one of the most promising technology for the large scale energy storage. However, the high cost and the low energy density limit its further development. Mainly focus on the cost reduction and stability improvement,the paper firstly introduce the development status and prospect of the commercialized vanadium flow battery technology and summarize and analyse the developments in the domestic and foreign companies. Then, we overview the current status of the aqueous and nonaqueous flow battery new systems including their characteristics, problems and challenges respectively. Finally, raising the development requirements for flow battery technology with low-cost and high stability and paving the way towards high performance new system.

Key words: flow battery, vanadium flow battery, new system of flow battery
