Here we introduce a high-precision stack-pressure control and dilatometry tool to apply a uniform and constant stack pressure on electrodes independent of electrode swelling. By increasing stack pressure fourfold over typical initial values, we double the lifetime of graphite ‖ LiNi0.8Mn0.1Co0.1O2 cells, an industrially relevant battery chemistry, without altering active materials or electrolytes. This suggests that many lithium-ion batteries operate under sub-optimal stack-pressure conditions, leading to curtailed lifetimes. We demonstrate that different degradation mechanisms emerge outside the optimal pressure window: low stack pressure accelerates cathode cracking, whereas high pressure promotes lithium plating. Our findings highlight coupled mechanical–electrochemical degradation mechanisms and identify stack-pressure optimization as a practical solution for increasing cycling stability. While electrochemical degradation in lithium-ion batteries is well studied, the role of stack pressure in long-term cycling remains unclear. Here the researchers use a high-precision pressure-controlled dilatometry tool to optimize stack pressure and understand how it prolongs battery lifetime.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 7","pages":"1032-1042"},"PeriodicalIF":70.1,"publicationDate":"2026-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41560-026-02087-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148522972","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}

Nevertheless, they also intensify hydrogen crossover and safety concerns, thus mandating efficient mitigation strategies. Here we studied the correlation between cathodes and hydrogen crossover behaviours and mitigated safety risks by designing a gas recombination catalyst (GRC). We attribute the elevated hydrogen crossover associated with platinum-based cathodes to their preferential utilization for the hydrogen evolution reaction that creates elevated hydrogen supersaturation, as evidenced by direct measurements of dissolved hydrogen concentration. Varying the placement of platinum layers relative to the cathode–separator interface also supports this conclusion. The implementation of a GRC reduces hydrogen crossover by 95% without affecting LAWE performance and functions for over 1,000 h at 1 A cm−2. This study provides insights into hydrogen supersaturation and the crossover mechanism, as well as offering a promising pathway to enhance the efficiency and reliability of alkaline water electrolysis. Alkaline water electrolysers are being optimized for higher performance, but measures such as advanced electrodes or thinner separators can increase hydrogen crossover and safety risks. Here the authors analyse crossover behaviour and show that a gas recombination catalyst cuts crossover by 95% without affecting electrolyser performance.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 9","pages":"1319-1331"},"PeriodicalIF":70.1,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41560-026-02094-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336495","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}

Batteries and fuel cells can play a critical role in decarbonizing this sector. Here we conduct a life-cycle GHG assessment of class 3–8 internal combustion engine vehicles, hybrid electric vehicles (HEVs), fuel cell electric vehicles (FCEVs) and battery electric vehicles (BEVs) in the United States. Compared with conventional diesel-fuelled options, alternative powertrains reduce emissions across vehicle types: HEVs by 1–26%, FCEVs using hydrogen produced from steam methane reforming by 12–51%, BEVs powered by the grid by 44–68%, FCEVs using hydrogen produced from electrolysis powered by renewable electricity by 72–82% and BEVs powered by renewable electricity by 87–92%. The ordering of these powertrains holds across cargo weights, drive cycles, regional electricity grids and grid projections. We also assess renewable electricity consumption and hydrogen leakage, two factors that must be considered when evaluating the suitability of different powertrains for decarbonization. Decarbonizing medium- and heavy-duty vehicles is challenging, and the relative benefits of batteries versus fuel cells remain uncertain across applications. This modelling work shows that both reduce emissions versus diesel, but battery electric vehicles powered by renewable electricity deliver the lowest life-cycle greenhouse gas emissions in most cases.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 9","pages":"1350-1363"},"PeriodicalIF":70.1,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148336496","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 report a flowing Zn slurry (FZS) battery in which nanoscale Zn particles dispersed within a conductive network undergo reversible Zn/Zn2+ redox conversion with enhanced stability. Ligand-assisted confinement coordinates onto Zn nanoparticle surfaces, suppressing excessive Zn growth and parasitic reactions, enabling uniform, monodisperse Zn nanocrystal deposition throughout the slurry. In FZS | |Cu asymmetric cells at 8 mA cm−2, it achieves a Coulombic efficiency of 99.94%, whereas symmetric cells operate reversibly for 5,128 h at 22.5 mA cm−2, 135 mAh cm−2 under continuous flow. Extending from these results, FZS | |MnO2 full cells retain 81.1% capacity after 5,500 cycles at 10 A g−1, and FZS | | O2 full cells deliver 1.65 Ah over 100 h at 1.35 mA cm−2. This work demonstrates the viability of FZS for long-duration energy storage, providing a framework for scalable, stable metal-slurry-based flow battery systems. Aqueous Zn batteries are attractive for low-cost and safe energy storage, yet their practical use is hindered by limited reversibility. Here the authors report a ligand-confined, flowable Zn slurry that enables durable and efficient operation.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"11 8","pages":"1171-1183"},"PeriodicalIF":70.1,"publicationDate":"2026-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305411","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}
