About Anode Material Carbon-coated Silica Powder
:
Chemical composition and structure
Carbon-coated silica powder is mainly composed of two elements: silicon and carbon. Silicon powder is usually nano-sized and coated with a thin layer of carbon. This carbon layer can provide electron transport routes and protect the silicon powder from oxidation or corrosion. At the same time, the carbon layer can also improve silicon powder's electrical conductivity, so it performs better in electrochemical reactions.
Physical property
These properties make carbon-coated silica powders widely used in batteries and electrochemistry. In addition, due to its nanoscale structure, carbon-coated silicon powder also has good dispersion and processability, which helps to improve its utilization and stability in electrode materials.
Chemical property
In addition, due to the presence of the carbon layer, it also has good oxidation and corrosion resistance. These properties make carbon-coated silicon powder have excellent performance in various chemical reactions, such as battery charging and discharging, electrochemical energy storage, etc.

Production Method of Carbon-coated silicon powder as an anode material
:
Prepare raw materials
The production of carbon-coated silica powder requires the preparation of silica powder and a carbon source. Silica powder generally uses nano-grade silica powder with high purity, and carbon sources can use hydrocarbon compounds such as methane and acetylene or carbon materials such as graphite and carbon black.
Mixed material
The silicon powder and the carbon source are mixed proportionally to form a uniform mixture. Physical methods such as ball milling and stirring can be used when mixing, and chemical methods such as solvent heat treatment can also be used.
Heating reaction
The mixture is placed in a high-temperature furnace and heated to a specific temperature under the protection of an inert gas so that the silicon powder and the carbon source react. It is necessary to control temperature, pressure and other parameters in the reaction process to obtain high-quality carbon-coated silica powder.
Collection and processing
After the reaction, the product is removed from the high-temperature furnace for cooling and collection. The collected carbon-coated silica powder must undergo subsequent treatment, such as cleaning, drying, screening, etc., to remove impurities and unqualified particles and obtain high-purity carbon-coated silica powder.
Packaging and storage
The treated carbon-coated silica powder needs to be packaged and stored. Suitable sealing materials such as polyethylene can be used when packaging to prevent oxidation or moisture. When storing, choose a dry, cool, ventilated place to avoid direct sunlight and high temperature.
