The doping modification method is flexible with various doping elements, and the research on this method is quite active. The inclusion of non-carbon elements in graphite can change the graphite's electron state, making it easier to acquire electrons, thus further increasing the amount of lithium ion embedded. For example, phosphorus atoms and boron atoms are successfully doped on the surface of graphite and form chemical bonds with them, which contributes to the formation of dense SEI film, and effectively improves the cycle life and rate performance of graphite after removal of iron by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
Doping different elements in graphite material has different optimization effect on its electrochemical performance. Among them, the addition of elements (Si, Sn) with the same capacity of lithium storage can significantly improve the specific capacity of graphite anode material. Different manufacturers of doping elements are different, product performance is very different, doping modification to improve the specific performance of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron graphite effect is significant, high-end artificial negative products to make differentiation of the key process.
