On February 22, "863" project "redox flow battery energy storage system research and development" directed by Zhang Huamin has made great progress. 10-kilowatt vanadium flow storage battery system was successfully developed and the system is stable. The energy efficiency was over 80%.

Compared with other batteries, flow storage battery is the first choice of large-scale energy storage technology due to its high energy efficiency, electrical storage capacity, low cost. It can be used to adjust the wind and other renewable energy to supply power stably. And also can be used to balance the "load shifting" to achieve energy efficient and the backup power supplies of important sectors and large electricity companies.
