Vanadium redox flow cell (VRB) is the largest, most advanced and most industrialized high-efficiency reversible fuel cell in the world. It has a series of unique advantages such as high power, large capacity, high efficiency, low cost, long service life, green environmental protection, fast response speed and high safety. It is widely used in wind power generation, photovoltaic power generation, power grid peak shaving, distributed power station, special energy storage, transportation, municipal management, communication base station UPS power supply and other fields, and has extremely good application prospects. In Japan, Canada, the United States, Australia, Western Europe and other countries and regions, lead-acid batteries with small capacity, short service life and high pollution have been replaced.

With the rapid development of vanadium battery technology, vanadium battery will bring an unprecedented, significant and far-reaching new energy industry revolution to mankind, which is of great significance to China's sustainable development strategy.
