Abstract:
With the adjustment of the global energy structure and the rapid development of renewable energy, the scale of new energy storage has expanded rapidly. Among them, vanadium batteries have developed into a new type of energy storage “upstart” due to their advantages of high safety, long cycle life, easy expansion, environmental protection and easy recycling, and low life cycle cost, and have attracted market attention. Understanding the demand trend of vanadium resources under the development of new energy storage is of great significance for the rational development and utilization of vanadium resources and industrial layout of our country. By collecting and sorting out related data information of vanadium resources, this paper reviews the distribution characteristics and supply-demand structure of global vanadium resources, and the demand trend of vanadium resources is analyzed. The study found that vanadium resources are abundant in the world, mainly magmatic type (70%) and sedimentary type (30%), which are mainly distributed in Australia (45.2%), Russia (26.6%), China (23.4%) and South Africa (4.0%). In terms of supply and demand pattern, the global supply and demand of vanadium resources are concentrated in the steel industry, the raw material for production are mainly vanadium slag obtained from vanadium titanium magnetite steelmaking (73%); the demand side is mainly used in the field of iron and steel metallurgy, accounting for about 90% for a long time. The rapid development of new energy storage and the maturity of vanadium battery technology will drive the rapid growth of vanadium resource demand, and the transformation and development trend of vanadium industry is emerging. Vanadium battery will become the main growth point of vanadium resource demand, the proportion of consumption continues to increase, and the proportion of consumption in the field of iron and steel metallurgy continues to decline, breaking the vanadium industry pattern mainly applied in the steel industry. In view of the above situation, the research puts forward: firstly, increase the investment in vanadium resource exploration, release the import of vanadium slag; secondly, strengthen the exploitation and utilization of vanadium resources in stone coal; thirdly, accelerate the recycling of vanadium resources; the fourth is to optimize the layout of vanadium resource development and strengthen the guidance of vanadium resource production planning, industrial policies and standards.
