As a key part of the energy revolution, energy storage technology has attracted extensive attention from the global market and scientific community since the 21st century.
Among them, once lithium-ion batteries came out, they swept the entire consumer electronics market with their advantages of high energy density, and quickly entered the field of transportation, becoming a pillar technology supporting the development of new energy vehicles. In addition to the consumer field, in the electrochemical energy storage power station, lithium battery also accounts for a considerable proportion. According to the data, by the end of 2021, lithium battery energy storage accounted for 90 percent of the projects that have been put into operation9%。
However, while developing rapidly, its lack of security has also been exposed. According to the incomplete statistics of the national energy information platform, in the past 10 years, there have been more than 30 energy storage power station accidents around the world.
Once upon a time, all-vanadium flow batteries could only become a technical route to compete with lithium batteries in research reports. However, as the National Energy Administration pays more and more attention to the safety of energy storage power stations, vanadium batteries have once again entered people's field of vision with their safety performance and cost advantages.
The four advantages of vanadium batteries are the "soft underbelly" of lithium batteries: first, water-based batteries, which have no safety risks at room temperature and pressure;The second is 25 years of ultra-long life;Third, it is environmentally friendly, the capacity can be restored, and the electrolyte can be recycled foreverFourth, medium and long-term energy storage of more than four hours.

In June 2022, the National Energy Administration issued the "25 Key Requirements for Preventing Power Production Accidents (2022 Edition) (Draft for Comments)", proposing that ternary lithium batteries and sodium-sulfur batteries shall not be used for medium and large electrochemical energy storage power stations. In August of the same year, nine departments including the Ministry of Science and Technology and the Electronic Information Department of the Ministry of Industry and Information Technology respectively issued the "Implementation Plan for Science and Technology to Support Carbon Peak and Carbon Neutrality (2022-2030)" and "Guiding Opinions on Promoting the Development of the Energy Electronics Industry (Draft for Comments)", all of which put forward requirements for the development of safe and economical new energy storage batteries.
Catalyzed by a series of policies, the vanadium battery industry has ushered in a period of large-scale development opportunities.
In the future, under the influence of various factors such as the continuous investment of first-class subsidies, the mature development of the industrial chain and the cost reduction of scale effect, the all-vanadium flow battery will transition from policy-oriented to market-oriented with its excellent characteristics, and its penetration rate will gradually increase. The research institute EVTark released the "Development of China's Vanadium Battery Industry in 2022", and it is expected that the new scale of vanadium batteries will reach 2 in 20253GW, the new increment will reach 45GW, the cumulative installed capacity of vanadium battery energy storage projects will reach 24GW, and the new market size will reach 40.5 billion yuan that year. At present, these domestic enterprises are actively deploying.
