Features Of Magnesium Carbonate For Battery Materials
As the price of gasoline continues to rise, people are paying more and more attention to new energy vehicles, which has triggered the demand for battery materials in the market, including manganese-based spinel, ternary materials and lithium iron phosphate cathode materials. Increasingly.
The battery material magnesium carbonate is also called electronic grade magnesium carbonate. The product characteristics of magnesium carbonate for battery materials have the following notable features:
The main content of magnesium ion is stable: the main content of magnesium carbonate is controlled at 40-42 (calculated as magnesium oxide). The stability of the main content is conducive to the precise addition of other materials during production. The current production process and production of domestic magnesium carbonate manufacturers In terms of technical level, to accurately control the magnesium ion content of magnesium carbonate, the lower limit is more difficult than the upper limit. The main factors affecting the content are the moisture and impurities of the product. For example, the product is not dried and the moisture exceeds the standard range and the content is unstable, and the impurity control is unstable.
Low magnetic impurities: Magnetic impurities will affect the performance of the battery. It is necessary to control the magnetic impurities. The magnetic impurities are generally less than 500 and are relatively stable. The detection method of magnetic impurities is the core technology in China. Only a few manufacturers can detect magnetic impurities. Removal is the key to the impurity removal process of magnesium carbonate.
Small particle size span: Magnesium carbonate is generally detected by a laser particle size analyzer in China. Its particle size D50 is about 2 microns, and D90 is about 20. The fineness is not as fine as possible. The most ideal state is when it is added in production. The particle sizes of other materials are similar, and they are all within the same span.
The characteristics of magnesium carbonate used in battery materials are summarized as the main factors including stable content, low magnetic impurities, and small particle size span. The above characteristics are also the main influencing factors for distinguishing product grades and costs.
