When particle overpotentials evolve as the square root of time, researchers attribute the mechanism to solid-state chemical diffusion. However, this practice has led to reported diffusivities ranging over four orders of magnitude. Here we demonstrate that modifying the liquid electrolyte increases the apparent diffusion overpotential of LixNi1/3Mn1/3Co1/3O2 particles, even in thin electrodes. This finding challenges the conventional interpretation that equates square-root-of-time overpotentials to solid-state diffusion. We further show that electrolyte-penetrating pores in agglomerate particles can generate diffusion-like kinetics even without any diffusion processes. Electrolyte-penetrated pores produce a transmission-line configuration in chemical capacitance, leading to diffusion-like electrochemical behaviour. This demonstration highlights that square-root-of-time overpotentials are not exclusive to diffusion. Electroanalytical methods should therefore seek to identify specific physical origins rather than assume solid-state diffusion a priori. This finding suggests that the Li chemical diffusion coefficients and charge-transfer resistances reported in literature should be revisited. Low-frequency electrochemical responses in lithium-ion battery electrodes are widely interpreted as signatures of solid-state lithium diffusion. Here the authors show that electrolyte penetration in porous cathode particles can generate similar diffusion-like behaviour independent of bulk diffusion.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 10","pages":"1480-1489"},"PeriodicalIF":70.1,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149222825","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}

Here we demonstrate a machine learning-guided vertical microrod generator (VMG) that generates a directional Laplace pressure gradient for rapid fluid flow, thereby realizing quasi-ballistic ion transport. VMG delivers 21.5% power conversion efficiency and 14.3 W m−2 power density, with stability over 30 days under ambient conditions and retaining the efficiency over 20% across 30 K ambient temperature span. Integrated VMG arrays can power commercial devices, including emergency lights and 36 W ceiling lamps. This work achieves efficient conversion of low-power-density atmospheric thermal energy into electricity, offering a practical pathway for reliable off-grid power supply. Evaporation-driven power generators are often limited by non-directional fluid flow, which reduces their efficiency.

However, their performance, stability and scalability are constrained by the recombination layer, which needs to simultaneously enable efficient charge recombination, high optical transparency and robust interfacial chemistry. Existing indium-containing transparent conductive oxides raise concerns regarding cost and sustainability, whereas silicon-based tunnel junctions suffer from parasitic optical losses. Here we show that titanium oxynitride (TiOxNy) can serve as a multifunctional, indium-free recombination layer that reconciles these competing requirements. Conductive TiOxNy enables efficient vertical carrier recombination, suppresses lateral leakage and provides anchoring sites for self-assembled monolayers (SAMs) via a tridentate binding configuration. As a result, we achieve power conversion efficiencies (PCEs) of 33.3% for 1.0-cm2 devices and 30.6% for industrial-size (207.87 cm2) tandems, with enhanced operational stability. Our results establish TiOxNy as a scalable and sustainable interconnection strategy for tandem photovoltaics. The interconnected recombination layer is key to advance perovskite/silicon tandem solar cells. Cao et al. show that titanium oxynitride reconciles the requirements for recombination layers, improving the efficiency and stability for tandem solar cells and modules.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 10","pages":"1459-1469"},"PeriodicalIF":70.1,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148587296","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}

Operating these devices at lower temperatures could simplify system design, reduce degradation and broaden material options, but few conductors exhibit sufficient ion mobility in this regime. Here we report a family of oxide-ion conductors based on ((Na0.5Bi0.5)n–1TinO3n)(Bi2O2) (where n = 4, 5, 7 and 8) Aurivillius-type thin films with promising low-temperature performance. These Aurivillius phases, characterized by periodic bismuth oxide layers and a tetragonally distorted Na0.5Bi0.5TiO3 lattice, establish well-defined periodic fast ion-conducting channels allowing ionic conductivity of 0.025 S cm−1 at 350 °C. Combining atomic-scale electron ptychography imaging with first-principles calculations, we attribute these intriguing properties to localized lattice stretching and the unique dual-ion conduction pathways induced by the specific bismuth oxide intercalation. Based on this design, we constructed fuel cells that achieve a maximum power density of 0.726 W cm−2 at 400 °C, showing promising potential for technological applications. Solid oxide-ion conductors are essential for high-temperature electrochemical technologies, yet few materials maintain sufficient ion mobility at lower temperatures, where degradation is reduced and a broader range of materials can be used for auxiliary components.

Consequently, recycling capacities must scale significantly from 2026 onwards, while recyclers face major challenges: meeting regulatory requirements, establishing efficient reverse logistics and coping with the growing complexity of return streams, system designs, cell formats, and evolving chemistries. Here we provide a comprehensive overview of current recycling technologies and assess their compatibility with both state-of-the-art and next-generation batteries, highlighting the technical and economic challenges of managing diverse battery waste. We show that although established processes are largely suitable for today’s lithium-ion chemistries, future systems such as sodium-ion and solid-state batteries will require process adaptation. Beyond technical aspects, we identify seven key trends to enhance recycling economics, optimize material flows and support the development of a fully circular battery industry in the future. The rapid growth of electric vehicles is creating a surge of end-of-life batteries. This Review evaluates current recycling methods, their suitability for emerging chemistries and the practical challenges for scaling a circular battery industry.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 8","pages":"1098-1110"},"PeriodicalIF":70.1,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148460013","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}

Climate change compounds these risks by simultaneously reshaping renewable supply and electricity demand in synergistic, region-specific ways. Here we show that long-term adequacy challenges in decarbonized grids arise from the interplay between meteorological conditions and system design, driven by prolonged renewable generation shortfalls tied to fine-scale infrastructure siting choices. Using 12-km climate projections with county-level power system optimization for New England and Texas, we find that climate change can increase resource inadequacy frequency up to fivefold by mid-century as rising cooling demand intersects with renewable resource declines or transmission bottlenecks. However, climate-informed planning provides cost-effective mitigation: Texas maintains adequacy at near-zero cost by pivoting wind capacity westward, while New England requires a modest 2.34% investment increase via solar and transmission expansion near load centres. Our findings demonstrate that achieving climate-resilient, decarbonized grids requires moving beyond aggregate capacity goals towards high-resolution, climate-informed spatial planning that reveals localized siting opportunities. Decarbonized grids may face rising resource adequacy risks as weather-driven renewable variability and climate change jointly affect supply and demand. A high-resolution model shows that these risks stem from multi-day power shortfalls and system design, but can be reduced through region-specific, climate-informed siting and transmission planning.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 10","pages":"1449-1458"},"PeriodicalIF":70.1,"publicationDate":"2026-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148459958","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}
