AI Technical Summary
In existing technologies, the utilization rate of graphite anode materials is low, especially since the fine powder produced by crushing is prone to agglomeration, resulting in limited improvement in the rate performance and cycle performance of the battery.
By subjecting the raw coke to heat treatment in an inert atmosphere and oxidation treatment in an oxygen-containing atmosphere, oxygen-containing groups are introduced to generate electrostatic repulsion. Combined with carbonization and graphitization treatments, a stable channel structure is constructed to solve the problem of easy agglomeration of pulverized materials, and a composite material with ultra-fast charging and high cycle performance is prepared.
It achieves 100% utilization of fine powder, improves the charging and discharging speed and cycle stability of batteries, reduces production costs, and provides a high-value by-product recycling route.
