Binder is a polymer compound used in electrode making to adhere the active substance to the collector fluid. The main function is to bond and maintain active substances.

In this paper, a series of hard carbon materials with adjustable structure were prepared using chitosan as carbon source, and the relationship between the evolution of hard carbon structure and the properties of sodium storage was analyzed.

Cement is a common building supplies, generally divided into ordinary Portland cement, Portland cement mixed materials and special cement, the use of Portland cement is more.

Recently, Applied Clay Science reported "High-pressure Raman scattering and X-ray diffraction study of kaolinite, Al2Si2O5(OH)4."

By X-ray diffraction of the material and analysis of its diffraction pattern, information such as the composition of the material, the structure or morphology of the internal atoms or molecules is obtained.

Many materials through rolling, extrusion and other deformation processes, or even if not deformed, the grains in the polycrystal show more or less statistical uneven distribution, this organizational structure is called texture.

The precursor of ternary material is a low-cost compound of variable valence metal, which will be oxidized in the air, and the higher the drying temperature, the more serious the oxidation degree, and the general choice of air atmosphere drying.
