Conventional approaches to mitigate crystallinity necessitate elevated operation temperatures of 50–60 °C. Interestingly, this work indicates that the predominant factor limiting ambient-temperature performance is the robust coordination between lithium-ion (Li+) and ether oxygen (EO), rather than the crystallinity. By rationally tailoring the Li+ concentration, this work effectively weakens the coordination strength, thereby enhancing the ambient-temperature electrochemical performance. An optimal SPE with EO: Li ratio of 9:1 exhibits remarkable ionic conductivity (1.76 × 10−4 S cm−1 at 35 °C), a high Li+ transference number (0.486 at 35 °C), and superior adhesion to electrodes in compression-free pouch cells. The practical feasibility of the SPE is demonstrated in solid-state Li-LiFePO4 cells achieving a specific capacity of 149.66 mAh g−1 at 0.1 C and 35 °C and 90.5% capacity retention over 100 cycles. The electrolyte also exhibits compatibility with high-voltage cathodes of LiNi0.6Co0.2Mn0.2O2 and LiNi0.8Co0.1Mn0.1O2 for high-energy Li-metal batteries. These new insights shed light on the rational regulation of SPEs in advanced solid-state batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"125 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143641142","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 in this work, this challenge is addressed by developing a photothermal system that synthesizes ammonia from nitrogen and natural seawater under simulated solar irradiation, employing ruthenium-doped barium tantalum oxynitride semiconductors. This method significantly enhances solar-to-ammonia conversion efficiency, providing a viable alternative to the energy-intensive Haber–Bosch process. Optimized at 240 °C, the system achieves an ammonia evolution rate of 5869 µmol g−1 h−1 in natural seawater. Moreover, detailed characterizations have shown that the use of seawater not only leverages an abundant natural resource but also improves the reaction kinetics and overall system stability. The catalysts maintain their activity and structural integrity over multiple cycles, demonstrating both the feasibility and the durability of this innovative system. Achieving a solar-to-ammonia efficiency of 13% and an overall energy conversion efficiency of 6.3%, this breakthrough highlights the potential to decentralize ammonia production, enhancing accessibility and sustainability. This approach combines the benefits of thermal and photocatalytic processes, marking a significant advancement in ammonia synthesis technology.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"6 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635383","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, the limited energy density remains a major obstacle to further advancement of NVP. Herein, a medium-entropy NASICON Na3.3V1.4Al0.3(MgCoNiCuZn)0.06(PO4)3 (NVAMP-0.3) is designed by introducing Al3+, Mg2+, Co2+, Ni2+, Cu2+, and Zn2+ to regulate configurational entropy. These NVAMP-0.3 achieve an elevated average operating voltage (3.33 V) and high capacity (138.1 mAh g−1, based on 2.3 Na+) through V3+/V4+/V5+ multi-electron reactions. By simultaneously enhancing capacity and voltage, NVAMP-0.3 exhibits an impressive energy density of 460 Wh kg−1. Furthermore, NVAMP-0.3 demonstrates excellent low-temperature tolerance with a capacity retention rate of 94.6% after 300 cycles at −40 °C. In situ XRD unveils the underlying cause of the unique phenomenon where the solid-solution reaction accounts for the faster electrochemical reaction kinetics of the V4+/V5+ compared to the V3+/V4+ redox. DFT calculations indicate that NVAMP-0.3 possesses superior electronic conductivity and reduced Na+ migration energy barriers. A pouch cell assembled with the NVAMP-0.3 cathode and hard carbon anode exhibits highly stable cycling (89.3% after 200 cycles at 1 C). This study provides valuable insights into developing NASICON-type cathodes with high energy densities for SIBs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"9 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635382","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}

Nevertheless, dendrite growth and unstable solid electrolyte interface (SEI) have seriously hindered the practical application of potassium-metal anodes. Therefore, to address the aforementioned issue, a brand-new method is proposed: electrodeposition to construct a KF-rich artificial SEI layer, which can improve the stability and cycle time of the K metal anode. The homogeneous KF-rich SEI layer is formed via an in situ reaction between fresh K metal and the electrolyte additive fluoroethylene carbonate (FEC) during electrodeposition. This exerts tremendous effects on protecting the electrode and inhibiting the growth of dendrites. With the uniform and robust SEI layer, the potassium-metal symmetric battery has been stably cycled for more than 1400 h in a conventional carbonate electrolyte (0.8 m KPF6-based electrolyte (EC:DEC = 1:1, v/v)). In addition, K||Prussian blue (PPB) batteries with this conventional carbonate electrolyte can be operated for more than 200 cycles with an average Coulombic efficiency of 99.4%. This study sheds light on the construction mechanism of the KF-rich artificial SEI layer on K-metal anodes.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"31 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635517","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 present performance data from up to 1 year of outdoor testing of MHP modules in Golden, Colorado. The module encapsulation architecture and encapsulant materials have a significant impact on module reliability, with modules containing a polyolefin elastomer (POE) in addition to a desiccated polyisobutylene (PIB) edge seal outlasting modules with only a PIB edge seal or PIB blanket. Nondestructive and destructive characterization of the field-tested modules points to module scribes and interfaces as areas of potential mechanical weakness and chemical migration, resulting in shunt pathways and increased series resistance. Finally, indoor accelerated stress testing with light and elevated temperatures is performed, demonstrating failure with similar scribe degradation signatures as compared to the field-tested modules. Under both outdoor testing and light and elevated temperature conditions, electrochemical corrosion between the copper electrode and the mobile iodine ions appeared dominant, with a significant progression at the scribes that is speculated to result from an interplay between the initial laser damage and joule heating from enhanced ion diffusion under bias.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"5 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635386","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, a one-step Coordination-Selective Synthesis strategy is developed to integrate Co single-atom sites and Fe-based nanoparticles within the same matrix, enabling long-range electronic interactions that enhance Co-N4 reactivity and improve oxygen reduction reaction performance. X-ray absorption spectroscopy confirmed that remote Fe-based nanoparticles modulate the electron distribution at Co-N4 sites. Structural characterizations reveal that the optimal catalyst, Co50%Fe50%-NC, contains metallic Fe, Fe3O4, and Fe4N species. Electrochemical measurements show that it achieves onset and half-wave potentials of 0.984 and 0.927 V versus RHE, surpassing Co100%-NC with only Co-N4 sites. Additionally, it demonstrates efficient oxygen evolution reaction performance, achieving an overpotential of 298 mV at 20 mA cm−2, comparable to RuO2. Density functional theory calculations reveal that Fe4N optimizes O-containing intermediate adsorption/desorption, lowering the theoretical overpotential.
