However, the further application is severely hampered by the sluggish reaction kinetics and stable thermodynamics. Introducing catalysts is an effective method to improve the reaction rate, but the catalytic activity tends to decrease with an increasing number of reaction cycles, due to the highly reductive Mg and H species. Herein, the spring effect has been observed in the P doped Li3VO4, in which both V─P and V─V bonds undergo compression and elongation during hydrogen absorption and desorption, respectively. Such a unique self-regulation spring effect not only improves the reaction kinetics of MgH2, but also maintains the high activity of P doped Li3VO4, thereby ensuring the hydrogen capacity of MgH2 even after 100 loops. This spring effect of chemical bonding, stretched-recovered-stretched with the motion between the highly reductive Mg and H species, will provide insight into catalyst design for hydrogen-related industries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"82 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858139","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 chemical interplays between the molecular spacers and the inorganic building blocks during crystallization cause substantial phase complexities in the resulting matrices. To successfully optimize and implement the quasi-2D HP functionalities, a systematic understanding of spacer chemistry, along with the seamless navigation of the inherently discrete molecular space, is necessary. Herein, by utilizing high-throughput automated experimentation, the phase complexities in the molecular space of quasi-2D HPs are explored, thus identifying the chemical roles of the spacer cations on the synthesis and functionalities of the complex materials. Furthermore, a novel active machine learning algorithm leveraging a two-stage decision-making process, called gated Gaussian process Bayesian optimization is introduced, to navigate the discrete ternary chemical space defined with two distinctive spacer molecules. Through simultaneous optimization of photoluminescence intensity and stability that “tailors” the chemistry in the molecular space, a ternary-compositional quasi-2D HP film realizing excellent optoelectronic functionalities is demonstrated. This work not only provides a pathway for the rational and bespoke design of complex HP materials but also sets the stage for accelerated materials discovery in other multifunctional systems.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"27 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867388","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, owing to the intrinsic vulnerability of Cuδ+ reduction during NO3RR, it is still challenging to develop highly active and durable OD-Cu catalysts. Herein, a unique strategy is reported to stabilize the Cu+ state by dynamically introducing metallic Ag clusters in the oxidized CuAgOx nanosheets to form heterostructure Ag0-CuAgOx. Operando X-ray absorption spectroscopy and diffuse reflection infrared Fourier transform spectroscopy reveal a strong correlation between NH3 production and Cuδ+ content in Ag0-CuAgOx, with peak performance achieved when Cu+ is maximized. Ag0 acts as an electron acceptor, preventing the over-reduction of Cuδ+ during NO3RR. The stabilized Cu+ in Ag0-CuAgOx helps achieve outstanding long-term stability of 400 h for NH3 production, surpassing most of the state-of-the-art Cu-based electrocatalysts. Computational studies and ultraviolet photoelectron spectrometer confirm that Ag0 functions as the electronic buffer and enables electron transfer from Cu2O to Ag to generate electron-deficient Cu sites, thus turning the Cu d-band center with favorable adsorption energies for key intermediates to facilitate NH3 formation. The study paves the way to develop valence-stabilized catalysts for a range of electroreduction reactions.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"14 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867389","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}

Degradation mechanisms during overcharge of LiNiO2 are well known at the material level featuring O2 gas release and concomitant surface reconstruction of LiNiO2. However, there are still debates regarding the role of the high voltage phase formation, so called O1, on gas production. Moreover, little information is available on the effect of produced gases on the cell components (anode or sensors), or the effect of overcharge on electrode level behavior. In this work, we simultaneously measure the gas evolution using operando mass spectrometry while spatially resolving nanostructure and crystallographic lattice parameter changes using operando micro small/wide angle X-ray scattering (SAXS/WAXS) mapping during the formation and overcharge of a LiNiO2/Graphite─Silicon pouch cell. This new correlated operando characterization experiment allowed to (1) confirm the absence of O1 phase even with substantial gas produced at end of charge, (2) unveil the effect of gases on reference electrode and (3) show that overcharge increases in-plane reaction heterogeneities by creating local degraded regions lagging behind the ensemble electrochemistry. These findings will be important to optimize ageing of devices based on similar chemistries, in particular Ni-rich cathodes, while showing the strength of correlated characterization leading to more efficient and robust information on complex mechanisms.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"107 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867386","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}

Platinum (Pt) based catalysts demonstrate superior activity toward acidic HER, but the scarcity of Pt metal presents obstacles for large-scale application. Therefore, constructing Pt single-atom catalysts (SACs) with maximum metal-atom-utilization efficiency renders a feasible strategy, which however is critically hindered by an unsatisfactory catalyst lifetime. Here, a general strategy is reported to develop novel HER catalysts with Pt single atoms immobilized on polyimide support, which can display an exceptional activity toward acidic HER while achieving an outstandingly high durability with negligible activity decay for 760 h of continuous operation at 100 mA cm−2. The detailed experimental and theoretical results unravel that, the polyimide support lowers the d-band level of Pt site with a reduced energy barrier for acidic HER and simultaneously promotes the proton concentration near Pt site, leading to appreciably improved HER kinetics. Additionally, the polyimide support is versatile toward immobilizing ruthenium, palladium, and other single metal atoms, providing an alternative approach to develop SACs with superior catalytic activity and durability.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"31 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867387","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}

Direct battery material recycling, emphasizing the rejuvenation of degraded materials, stands out as an environmentally benign alternative to conventional pyro- and hydro-metallurgical processes that are intrinsically destructive. In addition, given the surface, interface, and interphase as the major failure mechanisms in degraded materials, rapid heating technology (RHT) emerges as a promising direct recycling method, harnessing its distinctive kinetics and thermodynamics to trigger highly time- and energy-efficient, precisely defect- and interface-targeted approach to revitalize degraded materials. This review summarizes recent advancements in RHT-based LIB recycling strategies, focusing on active materials recovery, efficient regeneration, and reutilization, with emphasis on expedited kinetics and locally confined chemical reactions at interfaces. It also outlines the perspectives and future directions by emphasizing the need for re-manufactured materials to meet increasing application demands.

Herein, a multi-functional copolymeric solid/electrolyte interface (SEI) layer, self-assembling on Zn anode based on the click reaction between epoxy silane and thioalcohol, is employed to eliminate these side reactions. The dense and robust SEI layer can not only physically repel water from the surface of the Zn anode to effectively inhibit the chemical corrosion and HER but also facilitate the desolvation of Zn2+ to accelerate the kinetic process. Additionally, it also can regulate the interfacial ion flux and induce the preferred Zn plating with (002) crystallographic orientation, enabling dendrite-free Zn deposition. As a result, a stable Zn anode with a long cycle life of ≈200 h at a depth of discharge (DoD) of 60% is achieved.

Under light irradiation, the distinctive transformation characteristics of photoisomeric molecules are leveraged to effectively and continuously passivate dynamic defects. Meanwhile, ring-opening MC structure provides two anchoring sites, which form a stable chelating ring with undercoordinated Pb2+, thereby mitigating the risk of Pb leakage. Both theoretical analyses and experimental findings indicate that MC molecules expose more active sites due to their open molecular structure under illumination, thus tightly binding to undercoordinated ions (I− and Pb2+) in films. The MC passivation treatment exhibits an impressive power conversion efficiency (PCE) of 22.04%, while also improving hydrophobicity, UV resistance, and biocompatibility of films.
