LIBs contain a significant proportion (12%—20%) of graphite, crucial for their anode's electrode active material, sourced primarily through mining and synthesis. However, concerns arise as a few countries, notably China, Turkey, and Brazil, control over 78% of the world's natural graphite reserves, highlighting potential supply chain risks. In addition to that, synthesizing graphite is expensive, and with the ever-increasing demand for EVs, the prices are expected to increase even further. Recycling graphite from waste LIBs extracted from EVs and electronic devices could potentially be a secondary source of graphite. This recycled graphite source can mitigate supply chain risk, preserve natural resources, lower prices, and decrease environmental pollution. This comprehensive review examines various pretreatment techniques and methodologies for recycling graphite from waste LIBs. It also provides a comparative discussion on the purity and recovery of graphite, its challenges, and prospects in LIB recycling technologies. This review serves as a valuable guide for researchers seeking sustainable practices and recycling methodologies in the EV industry.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3341 - 3369"},"PeriodicalIF":2.7,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142453014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering this, this study proposes an improved BPNN identification method based on Bayesian regulation optimization.

The spectral data was preprocessed by Savitzky-Golay smoothing and multivariate scatter correction. Competitive adaptive reweighted sampling method was used to extract information from the spectral data.
