AI Technical Summary
Existing technologies cannot efficiently and accurately compensate for structural defects in waste graphite and are energy-intensive. Traditional methods involve energy waste and pollution risks, and there is a lack of effective co-remediation processes for waste resin and waste graphite.
By combining multi-source waste resin with Joule thermal flash evaporation technology, resin-graphite composite material is formed through high-speed mechanical ball milling. The Joule thermal flash evaporation reactor is used to achieve instantaneous pyrolysis of the resin and deposition of a carbon layer within milliseconds, which specifically repairs graphite defects. Inert atmosphere annealing treatment is then used to stabilize the carbon layer structure.
It enables rapid and efficient repair of structural defects in waste graphite, improves the graphitization degree and electrochemical performance of recycled graphite, reduces energy consumption, and has the advantages of resource synergy and environmental friendliness.
