As the anode material of lithium ion battery, silicon nanopowder has the highest theoretical specific capacity (up to 4200 mAh/g), which is much higher than the carbon powder widely used at present, but the biggest disadvantage of silicon powder as the negative electrode of lithium ion battery is the process of alloying with lithium. In the case of a large volume change, the active material is det...

Specification of titanium dioxide nanopowder: The particle size is very small: an average particle size of 5 nm. Good dispersion performance: 5 nm titanium dioxide has good dispersibility and can be self-dispersed into pure water without stirring. The dispersed liquid can be sprayed onto the surface of the furniture and the wall to form a uniform nano-coating to purify the indoor air. High catalyt...

The granular shape of titanium powder includes spherical, polygonal, sponge, and flake shapes. The granular shape is related to the method of preparing titanium powder. The requirements for titanium powder generally include three aspects, namely purity, particle size and granular shape. Titanium powder is divided into 4 grades. The size of 1000-50um is coarse powder, 50-10um is fine powder, 10-0.u...

A photocatalyst is also called photocatalysis. Simply, a photocatalytic material undergoes light irradiation and does not change itself but can promote other substances to undergo a chemical reaction. There are many examples of photocatalyst reactions around us. The most typical is The chlorophyll, which plays the most important role in photosynthesis of plants, is a photocatalyst. Photocatalysts ...
