However, its efficiency is limited by a slow 6-electron transfer process, necessitating advanced electrocatalysts to accelerate the urea oxidation reaction (UOR) and moderate overpotential, thereby cutting energy losses. Developing efficient, affordable electrocatalysts is vital for practical urea electrolysis (UE) and improving UOR kinetics. Optimizing UOR electrocatalysts requires creating highly active sites, enhancing electrical conductivity, and manipulating electronic structures for improved electron transfer and intermediate binding affinities. This review explores recent advances in UOR catalyst design, focusing on transition metal-based catalysts, including nanostructures, phases, defects, heterostructures, alloys, and composites. It underscores the importance of understanding structure-performance relationships, surface reconstruction phenomena, and mechanisms through in situ characterization. Additionally, it critically assesses the challenges in UOR catalysis and provides insights for developing high-performance electrocatalysts. The review finishes with perspectives on future research directions for green hydrogen generation via urea electrolysis.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"29 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583078","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}

Current hydrometallurgical methods rely on three different classes of lixiviants, i.e., inorganic acids, organic acids, and deep eutectic solvents (DES). While inorganic acids show unmatched efficiency, their toxicity raises concerns over large-scale usage. Over the past decade, research on greener alternatives, e.g., organic acids and DESs, has made immense progress. The cradle-to-grave life cycle analysis of these lixiviants at an industrial scale is of utmost importance for the success of the recycling process. Here, we perform the overall impact analysis of representative lixiviants from each class based on their efficiencies and compare them on various sustainability parameters, e.g., climate change, eutrophication, and toxicity. The ramifications of each lixiviant system at an industrial scale, including their production, leaching and precipitation efficiencies under optimized conditions, and end-of-life treatments have been considered. The results highlight the importance of optimizing solid-to-liquid ratio to make recycling environmentally and economically viable, which is often ignored. These findings also underline the need for significant optimization of DES formulations to fully realize their potential at the industrial scales and several points toward this have been discussed.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"38 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583076","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}

To enable implementation in electric vehicles and other applications, 3D structuring is a method frequently proposed to allow for performance enhancement due to an increase in electrode surface area. Due to the decrease in lithium ion diffusion pathways, potential for application in thick electrodes exists, allowing further enhancement of energy density. Laser ablation is a promising manufacturing technique for the fabrication of 3D structured electrodes due to its ease of implementation in the existing electrode manufacturing process, as well as its flexibility and precision. This review details the main process parameters of the laser ablation process and their influence on the process efficiency and quality of generated structures. It further summarizes recent progress in finding the optimal electrode structure for both cathode and anode, and discusses the opinions on relative importance of cathode v. anode structuring.

However, sulfur cathodes based on sulfide electrolytes feature large volume expansion, unstable interfacial contact, and inherent insulating nature, which impedes the practical application of ASLSBs. Therefore, a systematic design of the cathode side of ASLSBs is crucial for ensuring a well-contacted, electrochemically stable cathode–electrolyte interface, and an effective ion-electron transfer network. Here, a comprehensive discussion of the latest strategies will be delivered, highlighting their effectiveness in improving the performances of the sulfur cathode in ASLSBs. First, the major challenges including slow oxidation kinetics and significant volume expansion of the sulfur cathode are dissected. Then, the focus is shifted to the degradation processes at the interface between the cathode and electrolyte. Subsequently, the improvement of ionic conductivity and stability of sulfide electrolytes by structural modulation is elaborated. Finally, based on the latest progress, we present a new perspective on constructing an efficient ion-electron transport network and a stable cathode-electrolyte interface, which offers insights and directions for achieving practical ASLSBs in the future.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"18 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143570205","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}

Such core-shell structure design reduces the detrimental phase transition through the interlocking effect, which improves the structural integrity of resulting cathode. Specifically, the rocksalt surface is structurally robust, mitigating interfacial parasitic reactions and stabilizing surface oxygen. With this unique design, the resulting cathode delivers a discharge capacity of 94 mAh g<sup>−1</sup> at 5C in the voltage range of 2.0–4.3 V and demonstrates excellent cycling stability with 76% capacity retention after 1000 cycles.

The efficiency of lab-scale solar cells has exceeded 20% and considerable attention is currently being given to understanding and minimizing the remaining loss mechanisms preventing higher efficiencies. While recent efficiency improvements are partly owed to reducing non-radiative recombination losses at open circuit, the low fill factor (<i>FF</i>) due to a significant transport resistance is becoming the Achilles heel of OPV. The term transport resistance refers to a voltage and light intensity-dependent charge collection loss in low-mobility materials. In this perspective, it is demonstrated that even the highest efficiency organic solar cells (OSCs) reported to-date have significant performance losses that can be attributed to transport resistance and that lead to high <i>FF</i> losses. A closer look at the transport resistance and the material properties influencing it is provided. How to experimentally characterize and quantify the transport resistance is described by providing easy to follow instructions. Furthermore, the causes and theory behind transport resistance are detailed. In particular, the relevant figures of merit (FoMs) and different viewpoints on the transport resistance are integrated. Finally, we outline strategies that can be followed to minimize these charge collection losses in future solar cells.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"1 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546096","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}
