Most previous studies on tungsten oxide for the application of electrochromic electrodes have focused on improving its electrochromic performance in the visible spectral region while neglecting electrochromic performance in the near-infrared (NIR) and infrared (IR) spectral regions. Previous research objects have focused on obtaining WO₃ conductive films with wider light modulation amplitude, shorter response time, and higher coloration efficiency in the visible region.

Chinese tungsten market is expected to continue to be strong in the short term as there are many positive news in the market. 

China rare earth price is weak in the week ended on Friday February 10, 2023. Under the interweaving of positive and negative factors, the buyer’s market has a greater advantage. 

China molybdenum price stabilized in the week ended on Friday February 10, 2023. Under the weak supply and demand, the enthusiasm of traders to enter the market was significantly lower than that before and after the Spring Festival. 

Cleaned tungsten wire refers to tungsten wire that has been treated to remove impurities and surface contaminants, resulting in a purer and more homogeneous wire. This type of tungsten wire is often used in high-temperature and high-performance applications, such as electrical discharge machining (EDM) and electron beam welding. 

Black tungsten wire is a type of tungsten wire that has been coated with a black oxide to enhance its corrosion resistance and provide a sleek, black appearance. Tungsten is a dense, metallic element with a high melting point, making it an ideal material for high-temperature applications, such as heating elements and electrical conductors.

China’s ammonium paratungstate (APT) and tungsten powder prices keep firm on February 8, 2023 as the increase of new guide prices for this month shored up market confidence. 

The introduction of carbon material into tungsten oxide to obtain tungsten oxide-carbon composites owns several advantages. One is that the composite material can integrate the advantages of tungsten oxide and carbon materials. Another is that it is more likely to form simple structures with high structural stability. Graphene is a flat monolayer based on a honeycomb lattice of single carbon atom layers.

When used as anode materials for lithium batteries, tungsten oxide suffers from structural collapse and rapid capacity drop during charge/discharge cycles due to large volume changes. In addition, their low electrical conductivity leads to poor rate performance. So far, there are some effective methods to improve the electrochemical properties of tungsten oxides. When O-vacancies are introduced into tungsten oxides, their conductivity may be greatly improved, and researchers have tried to vary the vacancy concentration to obtain higher conductivity while employing nanostructures in SCs and LIBs.
