Ammonium metatungstate (AMT) can be toxic if ingested or inhaled in large quantities, and can also cause skin and eye irritation upon contact. However, AMT is not considered to be highly toxic under normal usage and exposure conditions.

Tungsten trioxide (WO3) is a material that has been researched for its potential use in lithium ion battery.. Lithium-ion batteries are widely used in various portable electronics, as well as electric vehicles and energy storage systems, and there is ongoing research to improve their performance by finding new materials.

Nano tungsten trioxide (nano-WO3) has several properties that make it a promising candidate for use in lithium-ion battery. The small size of the nano-WO3 particles results in an increased surface area, which enhances its electrochemical performance. Additionally, the unique nanostructure of nano-WO3 helps to improve its conductivity and lithium ion diffusion, making it possible for the battery to charge and discharge faster.

Lithium ion batteries are widely used in various portable electronic devices, as well as in electric vehicles and energy storage systems. The search for new materials to enhance their performance, increase their energy density and stability, is a current topic of research. One of the promising materials is nano tungsten trioxide.
