This paper develops a value chain analysis (VCA) model, with a consideration of value retaining processes (VRPs), which combines physical and monetary value flows of lithium (Li) for China’s lithium-ion batteries (LIBs) sector. The results indicate that the largest stages of value creation in China’s LIBs supply chain are Li chemicals refining and LIBs-powered products production, while an estimated economic loss happens at end-of-life (EOL). Results also highlight three main issues that affect value addition in the whole chain, including: (1) price volatility of upstream raw materials; (2) VRPs conducted at EOL; (3) international trade dynamics in the downstream LIBs and LIBs-powered products. Therefore, targeted policies to enhance CRMs traceability along LIBs value chain and stringent regulatory requirements for EOL recovery are needed to enhance resilience, maintain value, and sustainability. These need to be accompanied by international cooperation to globally address lithium supply chain risks and reduce associated impacts.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"222 ","pages":"Article 108452"},"PeriodicalIF":11.2,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144261979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Unlike conventional lithium-ion batteries (LIBs) with liquid electrolytes, polymer SSBs contain different materials such as flexible polymers, metal anodes and composite cathodes, which influence the overall recyclability. However, the recycling of polymer SSBs remains underexplored, and current research is usually limited to individual components of the polymer SSB. Therefore, it remains unclear how polymer SSB full cells with higher material complexity affect the state-of-the-art recycling processes. Here, a novel mechanical-hydrometallurgical process flowsheet has been developed to recycle polymer SSBs. Unlike conventional LIBs, polymer SSBs do not yield a black mass fraction during mechanical recycling. However, optimized mechanical pre-treatment was essential for hydrometallurgical extraction of valuable components. An innovative salt leaching process using Cu(II) sulfate was developed for the safe aqueous recycling of Li metal anodes in polymer SSBs. Compared to conventional lixiviants, this salt-leaching approach based on cementation significantly decreased H<sub>2</sub> emissions by up to 91 %, thus improving operational safety by mitigating the risk of an explosive atmosphere. Additionally, Cu(II) sulfate leaching achieved high leaching efficiencies for Li, Fe, and P exceeding 96 %. After impurity removal by hydroxide precipitation, Li<sub>3</sub>PO<sub>4</sub> recovery was demonstrated as a suitable candidate for LiFePO<sub>4</sub> resynthesis. Overall, a high cumulative Li recycling efficiency of 90 % was achieved.
