At present, there is a consensus on the vanadium battery, government level and industry and academia, that vanadium batteries are most suitable for China's development. First of all, China's vanadium ore resources are abundant, with core technologies. Through cross-border integration, Chinese companies have mastered the world's key technologies for vanadium batteries. The characteristics of vanadium batteries are also suitable for the needs of China's power grid, with long life, re-discharge and high reliability. It can fully meet the needs of China's construction of smart grid. The full development and application of peak-sharing energy storage batteries will greatly improve the operating efficiency of the power system. For example, in 2010, the national power generation equipment capacity was 96.219 million kilowatts, of which thermal power was 70.663 million kilowatts, accounting for 73.4%; hydropower was 213.4 million kilowatts, accounting for 22.2%; wind power was 31.07 million kilowatts; nuclear power was 10.82 million kilowatts. The peaking capacity of thermal power in power generation is poor. Although China has implemented time-sharing electricity prices, the difference between peak and valley power generation is still large. Solving power peaking is a global issue. Vanadium battery is a major revolution in energy storage technology and is expected to break through the bottleneck of the development of new energy industry. "In recent years, China has been increasing its focus on environmental protection and low-carbon fields and policy support. In the foreseeable future, there will be more and more pure electric vehicles, taking a step back, even with the current market size, transportation. Power battery is also a huge market. But as we all know, since 2011, the country has paid attention to the environmental protection of lead-acid batteries. The Yangtze River Delta region has shut down more than 500 large and small lead-acid battery manufacturers, according to relevant departments. The plan, the country's 3,000 lead-acid battery companies, to shut down and integrate into 300 large-scale lead-acid battery companies, other small non-compliant environmental regulations will be reorganized and merged, these are directly in front of the battery industry and electric vehicle industry The bottleneck of development. How to solve the demand of these batteries, how to transfer capacity, are worthy of consideration by industry peers." Faced with the development of China's battery companies, Huang Youquan believes that "on the one hand, it may be replaced by lithium batteries, but according to government agencies' predictions, lithium batteries can only replace 5-10% of lead-acid battery market share, even if capacitors are counted, Most of them are still not settled. Lithium batteries also have stability and safety issues, and the biggest problem with lead-acid batteries is environmental protection." It is understood that the current solid electrolyte vanadium power battery has been close to the level of lithium battery in terms of electric power, charge and discharge, specific energy, etc., and has a comparative advantage over lithium battery and lead acid battery in terms of safety, service life and cost. . At present, China has an annual output of 130 million KVAH of lead-acid batteries, and a total of 68 million KVAHs were produced from January to June 2011. If it is calculated with a 12V/120AH car battery , it will have an annual output of 90 million. China's production accounts for 50% of the world. In 2010, sales of lead-acid batteries worldwide were approximately $66 billion. According to China's "New Energy Automobile Industry Development Plan" and the battery industry data in recent years, the total of three batteries of lead-acid batteries, electric vehicle batteries and electric vehicles is about 300 billion yuan. The market for wind power storage equipment and urban peaking energy storage equipment used in large vanadium reactors will be around 1100 billion. This is the general trend of national economic development has brought historic opportunities to the vanadium battery industry.

The direction of energy storage technology - vanadium battery
It is understood that the main advantages of vanadium batteries are deep, high current density discharge, long cycle life, fast charging, and low price compared to other energy storage devices. Vanadium batteries are very suitable for large static energy storage. However, vanadium batteries also have disadvantages, low energy density, large volume, and a relatively high price for large-scale energy storage applications and energy storage. Although each energy storage technology has its advantages and disadvantages, in the foreseeable future, there will be a coexistence of technologies such as sodium-sulfur batteries, vanadium batteries, and lithium batteries in the field of energy storage, competing with each other, and there is no technical monopoly. The situation of the entire market.
