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.
