Pratik Bhattacharyya, Dr. SUMAGNA PATNAIK This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-8836420/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract This Research paper presents an innovative approach to recycling spent anode graphite from discarded lithium-ion batteries, emphasizing the enhancement of electrochemical performance through asphalt coating. The research addresses the critical need for sustainable graphite resource utilization and environmental protection. The study introduces a novel asphalt coating method applied to purified spent graphite(PG) after impurity removal. The asphalt-coated purified graphite (ACPG) is thoroughly characterized using XRD, SEM,FTIR,EDS analyses, confirming successful coating and improved surface morphology conducive to electrolyte infiltration2. The electrochemical performance of ACPG with varying asphalt coating amounts is meticulously investigated. The findings reveal that a 20% asphalt coating amount yields optimal electrochemical performance, with an initial capacity of 335 mAh/g at a 0.1 C rate, surpassing that of uncoated purified graphite (PG) Additionally, the rate capability is significantly enhanced post-asphalt coating, demonstrating the method’s efficacy. The process also shows that the charge transfer resistance is also low in coated graphite compared to uncoated recycled graphite. The thesis underscores the asphalt coating method’s simplicity, effectiveness, and economic viability, offering promising prospects for industrial-scale processing of recycled graphite. The research contributes to the body of knowledge in lithium- ion battery recycling and presents a scalable solution to a pressing environmental challenge and reuses it in as a anode in LiB for further use.
