However, industry forecasts indicate that if large quantities of waste lithium-ion batteries are not managed properly, it could lead to serious environmental pollution issues as these batteries reach the end of their life cycle. Therefore, developing highly efficient and environmentally friendly recycling technologies is urgently needed. This paper proposes a green and efficient selective lithium extraction process integrating leaching technology with electrochemical methods. This approach enables the separation of Li and FePO<sub>4</sub> within an electrolyte through electric field assistance while effectively minimizing waste liquid generation. The effects of various factors on Li and Fe’s leaching rates were investigated using orthogonal and single factor experiments. Under optimal conditions, the leaching rate of Li reached 98.85%, while that for Fe was only 0.22%, resulting in a selectivity ratio (Li/Fe) of 99.78%, which demonstrates successful selective extraction of lithium. Furthermore, we assessed the feasibility of this experiment through potentiometric-pH diagrams. We elucidated its mechanism using XPS, XRD, and SEM. Unlike conventional destructive leaching methods, the Li extraction process facilitated by the electric-field-induced assistance resembles the charging process of LiFePO<sub>4</sub> batteries. Ultimately, Li was recovered as Li<sub>2</sub>CO<sub>3</sub>, while Fe and P present in the slag were subsequently retrieved as FePO<sub>4</sub> with battery-grade purity through a hydrothermal method. This study presents an environmentally sustainable and economically viable approach for recovering spent LiFePO<sub>4</sub> batteries.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"19 ","pages":"Article 100198"},"PeriodicalIF":12.4,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143386386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 2000, global carbon dioxide (CO<sub>2</sub>) emissions from active fires have been approximately 25% of those from fossil fuels and land use change. Due to the complicated mechanisms of interactions between active fires and GHG emissions, the size, distribution, and changes of GHG emissions from active fires contributions exist wide differences. The contributions of active fires to GHG emissions and their discrepancies as well as driving mechanisms at the global scale remain poorly understood systematically. Here, we combine GHG emission, active fires, land cover, temperature, and population products (2003–2021) to quantificat the spatio-temporal features of fires-induced GHG emissions and possible drivers. Although the proportions of GHG emissions from active fires showed a descending tendency with fluctuation, the annually totality almost kept increasing since 2003.

Most areas, where GHG emissions from active fires obviously exceeded that from fossil and bio fuels combustion, were sparsely populated. Over 43% of GHG emission contributions from active fires were counted in Brazil, the Democratic Republic of Congo, Kazakhstan, Mainland of Southeast Asia, and Australia.

Using transfer learning, this KGML framework transferred waterlogging processes to eight gridded crop models, enabling more accurate yield projections. We found that KGML could accurately replicate the behavior of the improved APSIM model under waterlogging conditions, achieving an R<sup>2</sup> of 0.83 and an RMSE of 272.3 kg/ha for yield loss simulations. Soil properties were identified as the primary factors influencing yield losses under waterlogging, highlighting the importance of optimizing soil conditions to mitigate the adverse impacts of excessive water. Across different scenarios, the improved crop model ensembles projected greater crop yield losses compared to the original simulated outputs, with additional losses (compared to the historical period) around 5.9%–7.3% during the two periods. Although global climate models were the primary source of uncertainty in T1 (2029–2059), crop models contributed more to uncertainty in T2 (2069–2099).
