However, their device-level performance, particularly regarding energy efficiency and long-term stability, remains inadequate for practical deployment. Here, we argue that a key constraint of membrane electrolysers lies in the absence of catholytes, which creates a local reaction environment fundamentally distinct from that of aqueous H-type or flow cell systems, thereby reshaping electrocatalytic behaviour at the device level. We highlight the profound impacts of this catholyte-free interface, including altered proton availability, carbonate issues, mass transport limitations, product crossover, and re-oxidation—each representing a forefront challenge for CO<small><sub>2</sub></small> electrolysis. By examining these emerging interfacial phenomena, we propose key strategies for advancing membrane CO<small><sub>2</sub></small> electrolysers, including membrane-anolyte integration, ionomer engineering, and <em>in situ</em> device diagnostics.

For the first time, our approach combines ultrasonic measurements and heat transfer analysis to diagnose the average temperature and heat capacity accurately, with an error of 2.81%. We furthermore link ultrasonic features to specific failure stages from early incubation to the onset of thermal runaway (TR), paving a new ultrasonic way to interpret the failure modes and early-warn the TR of LIB. Using the ultrasonic features, the TR warning can be 32.47 min ahead compared with commonly-used voltage clues.

Here, we develop an all-day continuous power and freshwater generator (ACPFG) that innovatively integrates thermoelectric and evaporative cooling technologies. During the day, sunlight is absorbed and converted into heat by a low-emissivity absorber, while passive water flow establishes a substantial thermal gradient across the system. At night, evaporative cooling lowers the temperature below ambient, creating an additional thermal gradient across the generator. This enables continuous operation day and night. Our system achieves an unprecedented peak power density of 1.837 W m–2 and a record-breaking freshwater collection rate of 0.986 kg m–2 h–1 under 1.0 sun irradiation. At night, it maintains an impressive open-circuit voltage of over 80 mV and a water collection rate of 0.0896 kg m–2 h–1, demonstrating its all-day production capabilities.

The effectiveness of SACs is influenced by complex electronic structures. Accordingly, precise tuning of these surroundings is crucial to fully utilize SACs. In this work, we demonstrated that the performances of SACs in LiPSs redox reactions can be optimized by vacancy engineering. This strategy can retain the benefits of SACs as anchoring and electrocatalytic centers for LiPSs, while optimizing their electronic structures to promote rapid charge transfer and enhance LiPSs conversion efficiency. Specifically, iron-based SACs supported on nitrogen-doped carbon containing abundant carbon vacancies (Fe-SAs/N-Cv) were tested as a sulfur host in Li-S batteries. Density functional theory calculations indicate Fe-SAs/N-Cv effectively anchors LiPSs and reduces the decomposition energy barrier of Li2S. Thermodynamic analyses further elucidate that Fe-SAs/N-Cv can accelerate the LiPSs redox reactions. As a result, Fe-SAs/N-Cv hosts exhibit excellent rate performance and superior cycling stability. Furthermore, we demonstrated that with Fe-SAs/N-Cv can be applied in Li-S pouch cells to achievestable cyclability.

Fossil feedstock-based production can be replaced by electrified chemical production, combining carbon capture and utilization (CCU) with electrolysis-based hydrogen. However, electrified chemical production requires vast amounts of clean electricity, leading to competition in our sector-coupled energy systems. In this work, we investigate the pathway of the chemical industry towards electrified production within the context of a sector-coupled national energy system's transition to net-zero emissions. Our results show that the sectors for electricity, low-temperature heat, and mobility transition before the chemical industry due to the required build-up of renewables, and to the higher emissions abatement of heat pumps and battery electric vehicles. The chemical industry transitions last together with high-temperature heat, beginning with methanol, then ammonia, the olefins, and finally the aromatics. To achieve the net-zero target, the energy system relies on clean energy imports to cover 41% of its electricity needs, largely driven by the high energy requirements of a fully electrified chemical industry. Nonetheless, a partially electrified industry combined with dispatchable production alternatives provides flexibility to the energy system by enabling electrified production when renewable electricity is available. Hence, a partially electrified, diversified chemical industry can support the integration of intermittent renewables, serving as a valuable component in net-zero energy systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"15 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144547340","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}

For wide-bandgap perovskites, however, the pronounced energy loss across the heterojunctions of the active and charge transport layers impedes multijunction devices from reaching their full efficiency potential. Here we find that for polycrystalline perovskite films with mixed-halide compositions, the crystal termination—a factor influencing the reactivity and density of surface sites—plays a crucial role in interfacial passivation for wide-bandgap perovskites. We demonstrate that by templating the growth of polycrystalline perovskite films toward a preferred (100) facet, we can reduce the density of deep-level trap states and enhance the binding of modification ligands. This leads to a much-improved heterojunction interface, resulting in open-circuit voltages of 1.38 V for 1.77-eV single-junction perovskite solar cells. In addition, monolithic all-perovskite double-junction solar cells achieve open-circuit voltage values of up to 2.22 V, with maximum power point tracking efficiencies reaching 28.6% and 27.7% at 0.25 and 1.0 cm<small><sup>2</sup></small> cell areas, respectively, along with improved operational and thermal stability at 85 °C.
