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. Zn-air batteries assembled with Co50%Fe50%-NC exhibited superior performance to Pt/C, highlighting its potential for bifunctional oxygen electrocatalysis. This study provides an approach for designing high-performance catalysts by utilizing synergistic interactions between atomic and nanoscale metal species.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"60 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635387","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}

In this contribution, a negatively charged neodymium-based film via in situ conversion (NCF-Zn) is presented that attracts Zn2+ ions and repels OH− and SO42− anions. Thereby, a higher Zn2+ concentration is mentioned to postpone the impoverishment of Zn2+ due to the over-fast kinetics, lower the nucleation barrier, and thus uniform the electrodeposition. Meanwhile, the side reactions on the Zn anode can be suppressed due to the repelling of OH− and SO42− anions. Taking these synergetic advantages, the NCF-Zn anode enables ultra-stable cycles for more than 2500 h in Zn|Zn symmetric cells at a current density of 10 mA cm−2 and impressive reversibility of 99.93% Coulombic efficiency in Zn|Cu asymmetric cells at a current density of 5 mA cm−2. Notably, the assembled MnO2|NCF-Zn full cell demonstrates remarkable long-term cycling stability, retaining 97.2% of its capacity at 1 A g−1 after 1000 cycles.

To address these challenges, an organic–inorganic dual-layer protective coating is developed to improve Li⁺ transport, provide electronic insulation, and isolate CO2 and H2O. Deep eutectic solvents (DESs) are used as electrolyte additives to promote a stable, inorganic solid electrolyte interphase (SEI) composed of Li3N, LiF, and LiCl, which enhance ionic conductivity, lowers surface energy, and suppresses dendrite growth. Additionally, an elastic Li-Nafion buffer layer is incorporated to mitigate volume expansion during cycling. This dual protection system significantly improves cycling stability, extending the lifespan of Li||Li and Li-CO2 batteries by 5.19 and 4.62 times, respectively, with a reversible cycle life of 4160 h. A pouch battery using this system also demonstrates exbatteryent stability, with 1400 h of cycling at 50 µA cm−2 and a cut-off specific capacity of 250 µAh cm−2.

However, they possess several challenges such as intrinsic dendrite growth and dead Li, leading to poor cyclability and coulombic efficiency (CE). In addition, the ultrathin Li metal can cause much faster degradation of performances than thicker one owing to the exhaustion of Li resource with less compensation. To address these problems, silver trifluoromethanesulfonate (AgCF3SO3, AgTFMS) is proposed as a functional electrolyte additive in carbonate-based electrolyte to buffer the dendritic Li growth and to provide enhanced cyclability. Interestingly, Ag metal derived from the AgTFMS exhibits lithiophilic properties through an alloying reaction with Li. Furthermore, the CF3 functional group of AgTFMS generates a physically stable LiF-rich solid-electrolyte interphase (SEI), which further suppresses the Li dendrite growth. An LiNi0.8Mn0.1Co0.1O2 (NMC811) full-cell comprising the ultrathin Li metal anode (20 µm) with AgTFMS additive reveals an excellent capacity retention of up to 88.2% over 200 cycles, as well as outstanding rate capability under harsh practical condition. As a result, the AgTFMS additive can pave a new dimension for the design of high energy density LMBs using the ultrathin Li metal anode.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"46 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599680","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, the strategy of region-dependent microscopic and macroscopic strain suppression is demonstrated to achieve efficient F-PSCs on silver nanowires (AgNWs) electrodes. Fundamentally, by introducing the region-dependent modification approach of functionalized polymer incorporation, the significant release of microscopic strain in perovskite film is demonstrated by effectively suppressing defects at places with crystallization orientation variation of perovskite surface/grain boundaries. Equally important, the gradient macroscopic strain is simultaneously eliminated by inhibiting the FA+ (formamidinum) gradient distribution in perovskite film's depth direction. The two-strain relaxations greatly enhance the mechanical durability of perovskite film, while also improving phase stability and suppressing ion migration. Finally, efficient F-PSCs (23% PCE, the highest value among reported F-PSCs) is realized with remarkable foldability, with efficiency maintaining 94% of its initial value even after 2000 times multidirectional folding at 0.75 mm curvature radius, which far exceeds the mechanical durability of typical ITO-based flexible PSCs. This work aids in comprehending strain modulation role for F-PSCs realization.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"86 1 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599560","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, for current electrocatalytic CO2 reduction reaction (ECO2RR) systems, realizing 100% CO2 conversion with simultaneously high overall CO2 conversion rate (i.e., single-pass conversion) and high Faradaic efficiency (FE) remains a significant challenge. Enhancing CO2 conversion rate often results in a decrease in FE, conversely, improving FE may limit the CO2 conversion rate. Metal–CO2 (M–CO2) batteries with CO2 conversion functions face similar challenges, particularly for reversible M–CO2 batteries, which do not accomplish net CO2 reduction because nearly all of CO2RR products are reoxidized to CO2 during subsequent charging process. Such electrocatalytic CO2 conversion system for carbon neutrality poses substantial challenges. This perspective provides an in-depth analysis of state-of-the-art ECO2RR systems and M–CO2 batteries, alongside the main strategies employed to address their respective challenges. The critical importance of achieving both a high CO2 conversion rate and high Faradaic efficiency is underscored for practical applications and to effectively close the carbon cycle. Furthermore, a strategic roadmap that outlines future research directions is presented, thereby facilitating the advancement of comprehensive CO2 electroconversion technologies.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"68 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599559","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, safety concerns and the limited lifespan due to Li dendrite formation hinder its practical application. The complex dendrite formation process involves nonuniform nucleation and radial growth, requiring a holistic strategy to simultaneously regulate both processes. In this work, a dual-aspect control strategy is developed by designing a protective layer composed of hydroxyapatite (HA) and a liquid crystal polymer (LCP). Electrochemical, microstructural, and computational analyses revealed that HA provides homogenous Li0 adsorption sites, enhancing Li nucleation kinetics and uniformity. Meanwhile, the LCP self-assembles into cation-selective channels, promoting Li-ion diffusion and regulating growth direction. This dual-aspect control significantly improved Li plating kinetics and mitigated Li dendrite formation. Benefiting from this strategy, the symmetric cell achieved a critical current density of 5 mA cm−2 and maintained a lifespan of 500 h at 3 mA cm−2. Furthermore, in Li–sulfur batteries, the cell exhibited exceptional high-rate cycling performance (>10 mA cm−2) with an average capacity decay rate of only 0.056% over 1000 cycles. These results highlight the effectiveness of dual-aspect control in suppressing Li dendrites and improving high-rate cycling stability.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"70 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599558","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}
