However, its high volatility and corrosive nature can degrade the perovskite layer and promote the formation of byproducts and pinholes in the hole transport layer under thermal stress, ultimately compromising device stability. Here we introduce a non-volatile, solid-state alternative—4-(N-carbazolyl)pyridine (4CP)—which stabilizes lithium ions and facilitates the formation of lithium bis(trifluoromethanesulfonyl)imide complexes. Perovskite solar cells incorporating 4CP achieve a power conversion efficiency of 26.2% (25.8% certified) and maintain 80% of their initial performance for over 3,000 h at maximum power point tracking. The unencapsulated devices retain 90% of their initial efficiency after 200 thermal shock cycles between −80 °C and 80 °C, and under continuous exposure to 65 °C and 85 °C. The adoption of 4CP could help improve the stability of n–i–p perovskite solar cells.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"35 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025854","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}

Despite recent extensive efforts, achieving a long cycle life is still challenging at the 4.2 V cut-off (versus Na+/Na). Here we design a room-temperature isotropic epitaxial growth to achieve a relatively uniform and dense metal–organic framework epilayer on Na3V2O2(PO4)2F surfaces. Despite using polyethylene oxide, a typical ether-based solid polymer electrolyte, the cathode with isotropic epilayer exhibits enhanced cycling performance at the 4.2 V cut-off (retaining up to 77.9% of its initial capacity after 1,500 cycles). Combining experimental measurements and theoretical analyses, the key factor governing isotropic epitaxial growth behaviour is explicitly elucidated. Furthermore, we develop a self-designed high-sensitivity characterization method, in situ linear sweep voltammetry coupled with gas chromatography–mass spectrometry, to elucidate the failure mechanism of polyethylene oxide on Na3V2O2(PO4)2F surfaces and and to reveal the excellent electrochemical stability of the isotropic epilayer. Interestingly, the universality of this approach has also been validated, highlighting its strong potential as an effective strategy for enabling high-energy-density batteries.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"62 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144995657","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, managing the power exhausted from the core fusion plasma towards the reactor wall remains a major challenge. This is compounded in emerging compact reactor designs promising more cost-effective pathways towards commercial fusion energy. Alternative Divertor Configurations (ADCs) are a potential solution. In this work, we demonstrate exhaust control in ADCs, employing a novel method to diagnose the neutral gas buffer, which shields the target. Our work on the Mega Ampere Spherical Tokamak Upgrade shows that ADCs tackle key risks and uncertainties for fusion energy. Their highly reduced sensitivity to perturbations enables active exhaust control in otherwise unfeasible situations and facilitates an increased passive absorption of transients, which would otherwise damage the divertor. We observe a strong decoupling of each divertor from other reactor regions, enabling near-independent control of the divertors and core plasma. Our work showcases the real-world benefits of ADCs for effective heat load management in fusion power reactors. Managing power exhaust in fusion reactors is a key challenge, especially in compact designs for cost-effective commercial energy. This study shows how alternative divertor configurations improve exhaust control, enhance stability, absorb transients and enable independent plasma regulation.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 9","pages":"1116-1131"},"PeriodicalIF":60.1,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41560-025-01824-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144995671","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}

Typically, values are limited to around 1 mA cm−2, even, for example, for garnets with a relative density of >99%. It is not obvious that simply densifying ceramic electrolytes will deliver high plating currents. Here we show that plating currents of 9 mA cm−2 can be achieved without dendrite formation, by densifying argyrodite, Li6PS5Cl, to 99%. Changes in the microstructure of Li6PS5Cl on densification from 83 to 99% were determined by focused ion beam-scanning electron microscopy tomography and used to calculate their effect on the critical current density (CCD). Modelling shows that not all changes in microstructure with densification act to increase CCD. Whereas smaller pores and shorter cracks increase CCD, lower pore population and narrower cracks act to decrease CCD. Calculations show that the former changes dominate over the latter, predicating an overall increase in CCD, as observed experimentally.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"33 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144987440","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}

We demonstrate lithium metal batteries achieving a 5–70% state of charge (SoC) within 12 min over 350 repeated cycles at a 4C (8.4 mA cm−2) charging rate, as well as high-energy designs delivering projected energy densities of 386 Wh kg−1 reaching a 10–80% SoC within 17 min over 180 cycles.
