In recent years, global environmental problems are becoming more and more prominent and serious, and non-renewable energy sources are continuously consumed with the development of society, so energy storage of renewable energy sources becomes especially important. Considering the problems of unstable, discontinuous and unfavorable use of renewable energy sources such as solar and wind energy, appropriate energy storage equipment is urgently needed to enable efficient use of the resources. Vanadium battery is a relatively mature liquid current battery with long life, high energy storage, easy maintenance, flexible design, green and other outstanding advantages, commonly used in renewable energy storage and smart grid peak shaving, with high economic value and development prospects. China is not only the world's largest vanadium ore resource country, but also the largest producer and consumer of vanadium, occupying an important position in the international vanadium market, and the rich vanadium ore resources have played a positive role in promoting the development and application of vanadium liquid flow batteries in China. This paper highlights the development status of vanadium liquid flow batteries, the distribution of vanadium ore resources, and makes relevant suggestions for the development of vanadium liquid flow battery industry.
