In this study, we manipulate the crystal growth and spectral response of MA-/Br-free CsFA-based perovskite to minimize the V_loss^(non-rad) by rationally introducing methyl (methylsulfinyl)methyl sulfide (MMS) into the precursor. MMS effectively inhibits the oxidation of halide and reduces the formation of δ-phase perovskite during the phase-transformation, resulting in the formation of a high-quality perovskite film with fewer defects and reduced non-radiative recombination. Notably, a 5 nm of red-shift in the band edge of perovskite is achieved, providing an additional integrated current density of 0.24 mA/cm2. Consequently, a certified efficiency of 26.01% from the reverse scan along with a quasi-steady-state output efficiency of 25.30% is achieved for the 0.09-cm2 inverted PSC, marking the highest values for inverted PSCs based on MA-/Br-free CsFA double-cation perovskite to date. The champion device exhibits a minimal V_loss^(non-rad) of 67 mV. The present stategy is also extended to a minimodule with active area of 12.96-cm2 by delivering an efficiency of 22.67% from the reverse scan. Moreover, the target devices demonstrate great thermal and operational stability. This study offers an versatile Lewis base for regulating the crystal growth and spectral response of perovskite films, and emphasizes the significance of minimizing the V_loss^(non-rad) for high-performance inverted PSCs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"124 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880029","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 poor cycling stability of the aluminum (Al) metal anode arising from much more severe non-planner deposition than the other metals, especially at high current densities, limits their practical applications. Herein, we use classical metal electrodeposition theory to understand the aluminum deposition behavior and show a simple and practical way, that is, regulating the exchange current density (i0)/limiting current density (iL), the descriptor for metal deposition behavior, for uniform electrodeposition of aluminum metal. The regulation is realized by an electron-insulating polydimethylsiloxane (PDMS) coating. By carefully tuning the coating thickness, we can regulate the exchange current density to optimally balance mitigating interphase reactions while maintaining efficient mass transport. As a result, a stable Al metal anode reaction over 2800 hours is obtained under the exceptionally large current density of 5 mA cm-2 and a large deposition capacity of 5 mAh cm-2. The full cell with artificial graphite cathode delivers a stable discharge capacity of 65 mAh g-1 and a high CE of 99.5 %, without apparent capacity or CE decay over the 2500 cycles. This work presents a new strategy for regulating electrodeposition for Al metal anode and demonstrates an electrodeposition principle for metal anode batteries.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"22 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874665","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}

Various configurations of different electrodes and electrolytes in energy storage systems have been explored to take advantage of different charge storage mechanisms. We summarize critical studies that employ in-situ and operando techniques to identify the specific charge storage mechanism in these systems and discuss the factors influencing the energy density and power density of energy storage systems and strategies to improve them.

However, the key to unleash full potential of SOR for practical seawater electrolysis is to develop highly efficient and stable electrocatalysts able to sustain in harsh seawater environment at high current densities. Herein, we report the fabrication of nickel foam supported nickel telluride nanorod arrays covered conformally with an electrodeposited amorphous nickel molybdenum layer (NiTe@NiMo/NF), which exhibit outstanding SOR performance, capable of delivering 500 mA cm−2 at only 0.55 V vs. reversible hydrogen electrode (RHE) and operating at 500 mA cm−2 for 100 hours without degradation, in both simulated and natural seawater. Our comprehensive experimental and theoretical studies reveal that the NiTe@NiMo/NF electrode undergoes a dynamic reconstruction process, and the in-situ generated [MoO4]2− moieties can modulate and stabilize the catalytically active NiTe/NiOOH, improving the SOR activity and stability. Consequently, the asymmetric membrane electrode assembly comprising NiTe@NiMo/NF as the anode can deliver a current density as large as 5.0 A cm−2 at 1.33 V in alkaline natural seawater at 70 °C and operate at 1.0 A cm−2 below 1.0 V for 334 hours, holding great potential for energy-saving and cost-competitive hydrogen production from seawater.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"20 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858157","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}

Currently, most researches focus on constructing an inorganic-rich SEI, whereas the critical role of organic components is barely understood and thus hinders the rational regulation of SEI chemistry. Herein, tailored SEI composition with controllable organic/inorganic ratios on graphite surface has been obtained through simply adjusting the temperatures, and a series of experiments have been conducted to understand their ionic transport capabilities and stability using Prussian white/graphite full cells. The organic component is identified crucial in enhancing the kinetics. Consequently, the full cell with organic-rich SEI (such as -(CH2CH2O)n-) exhibits good rate capability, whereas the full cell with inorganic-rich SEI (such as KF) demonstrates excellent cycling performance. In contrast, the full cell with an organic-inorganic balanced SEI can provide fast K+ transport capabilities and good mechanical stability synergistically, thereby achieving good rate performance and cycling stability. Our research reveals the critical role of organic components in SEI to optimize K+ storage performance, which provides valuable guidance for the rational design of SEI and offers significant potential for the development of high performance PIBs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"31 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142849017","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}

Next, the created defects triggered concentrated electromagnetic wave attenuation, which further converted into Joule heating. Finally, these local high-temperature fields favored the spatial interlocking and topological conversion of Fe-macrocycles, as confirmed by multiscale spectroscopy, finite element analysis, and density functional theory.

Despite its significant impact on chemical reactions, solvents have not received the attention they deserve in semiconductor photocatalysis. By reviewing the historical development of this area, we argue that the limitations on solvent selection are becoming increasingly impractical. We explore the fundamental effects solvents have on semiconductor photocatalysis, breaking down their complex influence into three areas: semiconductor properties, interfacial charge transfer, and chemical reactions in the solution. This perspective highlights the urgent need for more comprehensive and systematic research on solvent effects. Although not often the main focus of many studies, several examples are provided to demonstrate the importance of solvent effects. Future research directions are also discussed.
