Among them, the vanadium flow battery technology is the most mature and has entered the industrialization stage. The all vanadium flow battery uses aqueous solution as electrolyte and the charging and discharging process is a homogeneous reaction, so it has excellent safety and cycle life (>10000 times), and has great application advantages in the field of large-scale energy storage.

Since Taller put forward the concept of liquid flow energy storage battery in 1974, China, Australia, Japan, the United States and other countries have started to research and develop it, and developed a variety of systems of liquid flow battery. This article will introduce the top 10 liquid flow battery companies in China in no particular order.
