Nano Tungsten Oxide Expected to Solve the Problem of Lithium-ion Battery Material Shortage

With the vigorous development of the new energy vehicle industry, the demand for power lithium-ion battery continues to heat up, causing many lithium-ion battery materials to face supply shortages. Many people in the industry said that whoever has the upstream lithium resources, nickel resources and cobalt resources will have the initiative to develop power batteries.

In view of the above situation, perhaps tungsten resources can effectively alleviate it. It is reported that in recent years, energy storage scientists have developed a lithium-ion battery using nano tungsten oxide as the electrode material, which has good physical and chemical stability, strong endurance and the advantage of civilian prices, mainly because of the oxidation tungsten powder is easy to prepare and has relatively new photoelectric properties. In addition, China is the country with the most abundant tungsten resources in the world, distributed in 23 provinces and autonomous regions, and its output ranks first in the world, that is, its reserves are four times the combined reserves of other countries in the world. Therefore, tungsten resources are considered by many people as one of the most likely mineral resources to solve the shortage of lithium-ion battery materials in the future.

At present, China is the world's largest lithium-ion battery market, and it faces a shortage of various lithium-ion battery materials, such as lithium resources. Domestic lithium resource consumption accounts for more than 40% of the world's total. Although China's lithium resource reserves account for 20% of the world's total, mining is difficult and costly, unable to meet domestic market demand, and has a high degree of external dependence. Therefore, Zheng Mianping, an academician of the Chinese Academy of Engineering, said that lithium raw materials can be extracted by improving the adsorption and membrane technology, precipitation method, ion exchange adsorption method and other methods to improve the recovery rate of lithium metal in the battery.

In short, there are many ways to solve the shortage of lithium-ion battery materials. Lithium battery companies can choose the appropriate way according to their actual situation.
