Natural Graphite Powder For Lithium Ion Battery

On February 12th 2019, we send 1 ton of 918-II natural graphite powder to Indonesia.

The natural graphite anode is processed from natural graphite. the domestic graphite reserves and production are abundant, and the mining cost is low. Natural graphite has a relatively complete graphite sheet structure and a high degree of graphitization, suitable for lithium ions to be deintercalated and shuttled therein.

The disadvantage is that the natural graphite is not modified and the cycle performance is poor. A common solution is to spheroidize to reduce the particle size and specific surface area of natural graphite, which will reduce the side reaction of the natural graphite anode with the solvent during the cycle;

Second, construct a core-shell composite structure, generally in modification The spheroidized natural graphite surface is coated with a thin layer of non-graphitizable carbon material (such as asphalt) to improve the stability of the anode material in the lithium battery;

Finally, artificially modify or change the surface state of the natural graphite, the same can be To achieve stability and durability of a single natural graphite negative electrode.
