Yet, granular PQR data and frameworks for assessing PQR inequities and guiding equitable electricity interventions remain sparse. To address this gap, we present a conceptual framework that leverages energy justice, capability and multidimensional poverty theories alongside concepts relating to power systems to quantify PQR inequities in sub-Saharan Africa. To demonstrate our framework and using 1 year’s worth of remotely sensed PQR data from Accra, Ghana, we assessed the distributive scale of PQR inequities, explored how multidimensional poverty exacerbates these inequities and examined the impact of PQR on households’ domestic capabilities. We found wider patterns of PQR inequities and a link between poor PQR and neighbourhoods with higher multidimensional poverty. We conclude that using remotely sensed data combined with justice and capability frameworks offers a powerful method for revealing PQR inequities and driving sustainable energy transitions. Poor power quality and reliability are prevalent in sub-Saharan Africa. Osunmuyiwa et al. find that areas with this issue in Accra overlap with those experiencing multidimensional poverty and have more unusable power during peak periods than others.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 3","pages":"395-403"},"PeriodicalIF":49.7,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-025-01717-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, academic research has focused on the active material of the electrode and little attention has been paid to cell-level design, hindering the realization of this goal. Therefore, upscaling high-areal-capacity electrode sheets is proposed as a practical way forward. Here we evaluate the impact of high-areal-capacity electrodes on cell energy densities, energy consumption during electrode fabrication and the cost efficiency of cell production. By examining the integration of scalable roll-to-roll electrode-manufacturing techniques (such as slurry casting and dry coating) with the materials chemistry of the electrode components, electrode structure design and cell performance, we aim to outline the areas of development for high-areal-capacity electrodes and provide a structured pathway for bridging the gap between laboratory innovations and industrial scale-up. Achieving industrial-scale production of high-energy-density batteries will require cost and efficiency challenges to be addressed. The authors explore the upscaling of high-areal-capacity electrodes, evaluating manufacturing techniques, electrode design and materials chemistry.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 3","pages":"295-307"},"PeriodicalIF":49.7,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495382","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}

However, severe capacity fading occurs due to surface degradation at the CAM–electrolyte interface and severe lattice volume changes in the CAM, resulting in inner-particle isolation and detachment of the CAM from the electrolyte. Here we quantified the capacity fading factors of Ni-rich Li[NixCoyAl1−x−y]O2 composite ASSB cathodes as functions of Ni content. Surface degradation at the CAM–electrolyte interface was found to be the main cause of capacity fading in a CAM with 80% Ni content, whereas inner-particle isolation and detachment of the CAM from the electrolyte play a substantial role as the Ni content increases to 85% or more. On the basis of the comprehensive understanding of these mechanisms in ASSBs, high-performance Ni-rich CAMs with columnar structures were developed through surface and morphology modification.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"65 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143452126","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}

However, they often face slow redox kinetics and poor cycling reversibility at high rate. Here we report using asymmetric solvent molecules substantially accelerates Li redox kinetics. Asymmetric ethers (1-ethoxy-2-methoxyethane, 1-methoxy-2-propoxyethane) showed higher exchange current densities and enhanced high-rate Li0 plating/stripping reversibility compared to symmetric ethers. Adjusting fluorination levels further improved oxidative stability and Li0 reversibility. The asymmetric 1-(2,2,2-trifluoro)-ethoxy-2-methoxyethane, with 2 M lithium bis(fluorosulfonyl)imide, exhibited high exchange current density, oxidative stability, compact solid–electrolyte interphase (~10 nm). This electrolyte exhibited superior performance among state-of-the-art electrolytes, enabling over 220 cycles in high-rate Li (50 μm)||LiNi0.8Mn0.1Co0.1O2 (NMC811, 4.9 mAh cm−2) cells and for the first time over 600 cycles in anode-free Cu | |Ni95 pouch cells (200 mAh) under electric vertical take-off and landing cycling protocols. Our findings on asymmetric molecular design strategy points to a new pathway towards achieving fast redox kinetics for high-power Li-metal batteries. There is growing interest in designing electrolytes to enable Li-metal batteries. Here the authors show that asymmetric solvents improve lithium redox kinetics and achieve long cycle life in anode-free cells under electric vertical take-off and landing conditions, demonstrating potential for future high-power applications.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 3","pages":"365-379"},"PeriodicalIF":49.7,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418056","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}
