The graphitized MATERIAL is transported to the ball mill through vacuum for physical mixing and ball milling. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic screening is carried out using 270-purpose molecular sieve. The material under the screen is tested, measured, packaged and stored. After the material on the screen is further ball milling to reach the particle size requirements, the screening is carried out. The doping modification method is flexible, and the doping elements are diverse, so researchers are more active in the study of this method.
Doping of non-carbon elements into graphite can change the electron state of the graphite, making it easier to gain electrons, thereby further increasing the amount of lithium ion embedding. For example, phosphorus atoms and boron atoms are successfully doped to the surface of graphite and form chemical bonds with it, which helps to form a dense SEI film, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field effectively improves the cycle life and rate performance of graphite.
Doping different elements in graphite materials has different optimization effects on its electrochemical properties. Among them, the addition of elements (Si, Sn) with the same lithium storage capacity can significantly improve the specific capacity of graphite anode materials. Different manufacturers of doping elements are different, product performance is very different, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC effect on improving the specific performance of graphite is significant, is the key process to make differentiation of high-end artificial negative products.
