To address this issue, we propose a facet-complementarity strategy through crystallization modulation utilizing a formamidine-based additive 1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-carboximidamide hydrochloride (FPPC) to control strain accumulation. The FPPC ligand shows strong adsorption on the (111) facet of perovskite via chemical interactions with octahedra lattice, promoting the formation of a more stable (111) facet against the preferred (100) orientation and achieving facet complementarity in the FAPbI3 film. Additionally, the increased dissociation barrier of the ligand-PbI2 bonding extends the crystallization growth window, allowing for a better lattice rearrangement and a balanced crystallization rate from bulk to surface. As a result, the facet-complementary devices achieve champion efficiencies of 25.63 and 24.26% on 0.09 and 1.0 cm2 scales, respectively, with greatly enhanced device longevity.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"137 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880079","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 interface and bulk degradation during cycling pose challenges for achieving low-pressure and high-performance solid-state batteries. In this study, we engineered a nonintrusive solid-state electrolyte rich in fluorine and boron and developed aluminum metal foils featuring a densely structured and highly lithiated interface, effectively suppressing interfacial contact loss and promoting the formation of a stable interfacial layer rich in fluorine and boron, helping to minimize fluctuations in Coulombic efficiency. With high areal cathode capacities (∼2.5 mAh cm–2), the low-pressure solid-state battery exhibited stable cycling performance for over 140 cycles, achieving an average Coulombic efficiency of 99.86%.

By probing the Si/carbonate electrolyte interface through a 25 nm-thick amorphous Si window/electrode, we detect molecular vibrational modes within a 10s of nanometers region adjacent to the Si surface and observe that PF6– anions react to form LiF at 0.5 V. Spatially resolved nano-FTIR spectra showcase subtle nanoscale heterogeneities in the initial solid/liquid interface and the resulting deposited LiF.

An impressive power conversion efficiency (PCE) of 19.60% was achieved in the PM6:BOCl-I-based device, which is one of the champion PCEs among the reported binary organic solar cells to date.

However, traditional techniques face challenges for large-scale deployment because of high energy and oversized separation unit requirements. Electrothermal swing adsorption uses conductive sorbent materials or conductive heating elements (electrodes) coupled to sorbents to induce CO2 desorption through electrical currents. The electrothermal approach offers energy efficiency and modularity to enhance the economic feasibility and scalability of carbon capture processes. This review examines various materials, including sorbents, heterogeneous catalysts, electrodes, and laboratory-scale advancements through fixed bed reactors for CO2 capture and parallel wire or open foam systems for CO2 conversion. The review offers insights into material selection strategies, emphasizing considerations such as porosity, catalyst stability, and cost-effectiveness. Finally, the review highlights the importance of an integrated electrothermal CO2 capture and utilization strategy and future research areas to advance the development of this crucial technology.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"24 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874148","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}

Considering the critical issues associated with residual lithium on high-Ni NCMs regarding greatly increased cost, deteriorated cycle life, and safety hazards, mid-Ni is recognized as a more reliable cathode to meet the urgent needs for cost reduction and safety enhancement pursued by LIB and electric vehicle manufacturers. To enable high-voltage mid-Ni LIBs, high anodic stability of electrolyte and cathode–electrolyte interface (CEI) are essential. Utilization of additives is a cost-effective strategy, and recent trends include the exploration of high-voltage solvents for better working electrolytes. This Perspective aims to highlight and discuss the key compounds that are usable as additives and/or solvents in high-voltage electrolytes at standard salt concentrations, specifically for mid-Ni LIBs, which are less flammable and form an inorganics-enriched robust CEI, and to provide insights into their function and applicability to improve the energy density, overall performance, and safety for next-phase LIBs.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"14 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874150","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}

When subjected to a high potential window, MXenes undergo an irreversible oxidative failure. However, the mechanisms behind this failure are not well understood. Here, we disclose a previously unreported ion-accumulation mechanism that limits the high operating potential of MXenes. Under excessive polarization at high potential, the representative MXene, Ti3C2Tx, shows oxidation behavior but a reversible electrochemical response. Spectroscopic analyses and electrochemical kinetic field simulations disclose the conformational state variation, ion flux distribution, and vertical displacement behavior of MXene electrodes, confirming that electrolyte ions predominantly accumulate at the edges of overly thick stacked MXenes, with only a limited number shuttling freely into the interior. To address this potential-limiting ion-accumulation mechanism, we develop a transferring–engraving method to build free ion-shuttling ultrathin MXenes that guarantees a 100% increase in the potential window and a high volumetric energy density of 45.7 mWh cm–3.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"201 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867210","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}
