       Tungsten oxide ultrafine particles with excellent performance and abundant reserves can be specially used to synthesize positive or negative materials for lithium batteries, thus contributing to the overall acceleration of the electrochemical process.

Sarah Maryssael, global supply manager of Tesla Battery Metals, recently told a meeting of mining executives and legislators in Washington that rare metal materials such as cobalt and nickel needed for power lithium battery production may face a supply crisis in the future, which is attributed to the fact that U.S. investment in mining minerals has not kept pace with the development of global resources.



Meanwhile, LG Chemistry filed a lawsuit against SK Innovation with the US International Trade Commission (ITC) accusing SK Innovation of hiring 77 former employees of LG Chemistry to steal trade secrets and produce "imitations of LG Chemistry", such as Kia Niro EV batteries, in the LG Chemical Lithium Battery Department. SK Innovation plans to start mass production in Hungary and the United States in 2020 and 2022, respectively, and supply Volkswagen's new electric vehicles in the European and American markets.

LG Chem asked ITC to ban the import of SK Innovation batteries that infringe on its trade secrets into the U.S. market. So far, the ITC has not ruled on the lawsuit.

With the increasingly fierce competition in the power lithium battery market, the shortage of raw materials has intensified the competition situation, which may lead to delays in the listing of some new electric vehicles of global automotive giants.

In order to solve the problem of tight supply of mineral resources and accelerate the arrival of the era of global electrification, some insiders said that cobalt, nickel and other materials can be replaced by tungsten and molybdenum metal compounds, such as tungsten oxide and molybdenum disulfide. Tungsten oxide is a kind of solid powder with moderate band gap, remarkable surface effect and strong ion absorption. It is a good choice for preparing electrode materials.
