Graphite Carbon Derived from Acetate Fiber as a Negative Electrode Material for Lithium-ion Batteries
As awareness of environmental safety continues to advance,the transformation of discarded cigarette filter(DCFs)into high-value products has emerged as a focal point of interest.Leveraging the consistent structure and mor-phology of acetate fibers within DCFs,pyrolysis studies were conducted on WCFs under high pressure.Specifically,a network-structured graphite carbon material(designated as HP-1000)was successfully synthesized within 15 minutes at 50 MPa and 1 000 ℃,yielding a remarkable 41.5%of the initial mass.When employed as a negative electrode material in lithium-ion batteries,HP-1000 demonstrated impressive specific capacity and rate performance,achieving a specific capacity of 105 mAh g-1 after cycling at a high rate of 5 C.Consequently,this research not only addresses the persistent environ-mental challenge posed by DCF waste but also contributes to the energy storage field by offering a high-performance and cost-effective graphite carbon negative electrode material.
