Notably, certain hallmark additives in LIBs, despite their proven effectiveness, fail in SIBs due to unclear mechanisms. This study reveals the critical role of reduced-state structures and electrostatic potential (ESP) distributions in predicting additive behavior. Using vinylene carbonate as a model, we demonstrate that even minor ESP variations can lead to divergent reduction pathways, forming detrimental sodium ethene glycol-like product (NED) in SIBs versus beneficial polycarbonate (LVDC) in LIBs. Furthermore, we establish that ESP similarities can effectively predict additive performance, explaining why fluorinated ethylene carbonate and trans-difluoroethylene carbonate exhibit distinct behaviors in SIBs. Beyond enabling rapid screening of LIB additives for SIB applications, our findings highlight how subtle differences in electrolyte microstructure can profoundly impact interphasial chemistry, underscoring the need for deeper investigations into electrolyte design.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"111 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Australia maintains its position as the world’s largest lithium producer, with output reaching 86,000 t in 2023, representing approximately 52% of global production, primarily sourced from hard-rock mines extracting spodumene in Western Australia. Direct lithium extraction (DLE) (6) technologies have demonstrated promising results; however, their real-world effectiveness and environmental impact remain uncertain as only 30% of tests have been conducted on actual brine sources. Balancing decarbonization goals with mining impacts requires stringent regulation and accelerated innovation in sustainable methods. Cobalt mining in the Democratic Republic of Congo (DRC), (7) which supplies about 70% of the global market, is plagued by widespread human rights abuses, including the exploitation of thousands of child laborers and hazardous working conditions in artisanal mines. Exploitation endangers the well-being of vulnerable populations and raises ethical concerns about the sourcing of critical battery materials, emphasizing the urgent need for sustainable and responsible practices within the LIB industry. The cobalt mining crisis in the DRC underscores the urgent need for robust, multistakeholder approaches to responsible sourcing, as recent reports reveal forced evictions, human rights abuses, and environmental degradation linked to industrial-scale mine expansions. Nickel mining in Indonesia and the Philippines, responsible for over 60% of global nickel production, is causing severe environmental devastation, including deforestation impacting thousands of hectares and heavy metal water contamination threatens local biodiversity and the rights of Indigenous communities, raising significant sustainability concerns in the LIB supply chain. Both countries face issues of water pollution, habitat destruction, and violations of Indigenous land rights, highlighting the urgent need for stricter regulations and sustainable mining practices to balance the growing demand for electric vehicle batteries with environmental and social responsibilities. South Africa, the world’s leading manganese producer, maintained its dominance in 2023 with an output of 7.2 million metric tons (36% of global production). Manganese extraction faces significant challenges, including the depletion of high-grade deposits, technological limitations in deep-sea mining, potential ecological disruptions to marine ecosystems, and economic feasibility issues, particularly as North America lack domestic supply. These challenges, combined with global shifts toward alternative battery technologies and ethical sourcing concerns, underscore the urgent need for South Africa to diversify its manganese industry, invest in local","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"1 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berlinguette","doi":"10.1021/acsenergylett.4c03584","DOIUrl":"https://doi.org/10.1021/acsenergylett.4c03584","url":null,"abstract":"This study is relevant to reactive carbon capture using aqueous alkaline capture solutions, where captured CO₂ is electrochemically released from a capture solution and then upgraded into commodity chemicals in an electrolyzer. The commercial viability of this form of reactive carbon capture demands that the electrolyzer effluent that is returned to the capture unit be sufficiently alkaline to effectively capture CO₂ from air or a point source. Here, we introduce “electron-alkalinity efficiency” (EA%) to correlate OH^– production to electrons consumed during the electrolysis of CO₂. We show that the maximum EA% value for CO production is 100%, but is less than 50% for the production of HCOO^–, CH₄, and C₂H₄. This outcome implies that the electrolytic production of CO yields the highest CO₂ capture efficiency. To support this claim, we modeled a 1-m² electrolyzer producing CO at a current density of 200 mA cm^–2, 100% Faradaic efficiency for CO, and 100% CO₂ utilization, resulting in an OH^– production rate of 75 mol h^–1. No other CO₂ reduction products (HCOO^–, CH₄, and C₂H₄) generate this level of alkalinity without operating at far more extreme current densities or larger scales. We therefore recommend to “go with CO” for reactive carbon capture.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"8 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
