Nanomaterials refer to materials (1-100 nm) with at least one dimension within the nanoscale in three-dimensional space. According to the classification of space dimension, nanomaterials can be divided into zero dimension, one-dimensional, two-dimensional and so on. Zero dimensional tungsten oxide mainly refers to nano tungsten oxide powders.

At present, lithium-sulfur battery is a kind of battery system with high energy density. Its theoretical energy density is as high as 2600Wh/Kg, which is much higher than other lithium-ion battery systems. Usually, lithium sulfur battery uses sulfur or sulfur based composite as positive electrode and lithium metal as negative electrode. Lithium-sulfur batteries have become a hot spot in battery research because of their high theoretical specific capacity (1675 mAh / g), low price, abundant reserves and relatively friendly environment.

Yellow tungsten oxide can be used to prepare pregnant women's warm clothing. Ordinary material warm clothing has the characteristics of softness, Wearing resistance, breathability and water absorption. With the advancement of society, technology is becoming more and more mature. In our environment, we can't avoid electronic devices with radiation, such as computers and cell phones. These devices will affect the healthy growth of the fetus. In order to satisfy a mother who can do whatever she wants without worry, scientists have racked their brains to study the warm clothing with yellow tungsten oxide. In addition to the features of ordinary thermal clothing, the yellow tungsten thermal clothing also has radiation, static and more thermal effects. What kind of properties does yellow tungsten oxide have to make it superior to other raw materials?

In the production of warm fiber, the use of ammonium metatungstate as an additive can make it far superior to the thermal fiber produced by other additives, such as: good thermal insulation and non-toxicity.
