At present, the spreading of COVID-19 is furious in the world. Several previous difficult viruses (such as HIV, HBV, PIV, etc.) have not yet been attacked, and new mutant viruses (such as SARS coronavirus, avian influenza virus, and H1N1 influenza virus, etc.) have appeared in humans, seriously affecting human health. 

As one of the most hot topics recently, cobalt-free lithium ion battery is considered as an upgraded version of the current commercial ternary lithium ion battery. Because of their higher energy density and lower production costs, they are popular among many battery manufacturers. As a typical transition metal N-type semiconductor material, how should nano tungsten oxide be used in cobalt-free lithium battery?

Analysis of latest tungsten market from Chinatungsten Online

The ferro tungsten and tungsten powder prices in the Chinese market remains stable when tungsten associations and listed companies declined their new offers for the market, which mainly due to lukewarm demand from end users after customers retreated from the market.

China rare earth price remains stable but shows signs of rise on July 9, 2020, but downstream buyers are not active in inquiry and thus market trading fails to meet market expectations. 

The ferro molybdenum, molybdenum oxide and molybdenum oxide prices still maintain stability as most market participants are waiting for a new round of rise. Both downstream and upstream companies control their stocks reasonably.

The tungsten powder and ammonium metatungstate(APT) prices in the Chinese tungsten market maintain stability due to deadlocked supply and demand in the market and unclear outlook of the economy. Moreover, the July and August are the traditional off season, which discourages the confidence of the whole industry.  

Rare earth market quotation in China: neodymium oxide, praseodymium neodymium oxide and praseodymium neodymium metal prices climbed slightly when market becomes active. But considering the deadlocked supply and demand, the whole market trading is thin. 

China molybdenum price is unchanged from the previous trading day owing to low trading activity, cautious sentiment of market participants and persistent weakness in the demand side under the continued spread of COVID-19. 

In May 2020, the tungsten content in the slag of Chenzhou Diamond Tungsten Products Co., Ltd. (hereinafter referred to as Chenzhou Diamond Tungsten) reached a record low, and the APT metal recovery rate reached more than 97%. Various technical indicators have been steadily increasing. The production and operation have marched forward and continue to promote tungsten smelting and upgrading.

Liquid batteries and solid batteries have their advantages and disadvantages, but the research team from the University of Texas at Austin claims to have found new all-liquid metal batteries that combine the benefits of both. The research team said that this is the first fully liquid metal battery that could work at room temperature and that the performance was significantly better than that of conventional lithium-ion batteries.
