Coated carbonization is a graphite carbon MATERIAL with PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal of iron as the "core", and a uniform layer of amorphous carbon material is coated on its surface to form particles similar to "core-shell" structure. The commonly used precursor of amorphous carbon materials are phenolic resin, asphalt, citric acid and other low-temperature pyrolytic carbon materials. The layer spacing of amorphous carbon materials is larger than that of graphite,
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC improves the diffusion performance of lithium ions in it, which is equivalent to forming a buffer layer on the outer surface of graphite, so as to improve the high current charge-discharge performance of graphite materials, and can also form a dense SEI film on the surface to improve the first effect and cycle life. Different manufacturers choose different precursors and heating procedures, which make the thickness and uniformity of the coating layer different, so that the product cost and performance will also be different.
First of all, the application of coating technology, leading technology, uniform thickness, and applied to the best-selling products of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC production process, can be used for high energy density fast charge consumption or power anode, other mainstream anode factories are also master, Low cost low end artificial negative electrode will not even use the coating carbonization process.
