Non-flammable solvents with a wide liquid range hold the key to safer LIBs with a wide temperature adaptability. Herein, a carboxylate-based weak interaction electrolyte is achieved by molecular design, which consists of EDFA (ethyl difluoroacetate), 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether, and fluoroethylene carbonate. The inherent non-flammable and wide liquid-rang features of the electrolyte ensure the safety as well as the wide operating temperature of a battery. The high affinity between FSI− anions and counter Li+ guarantees a stable and inorganic-components-dominated electrolyte/electrode interphase with rapid Li+ de-solvation kinetics, leading to perfect compatibility with graphite and avoiding side reactions between lithiated graphite and electrolyte. The rationally designed EDFA-based electrolyte enables the thick graphite (4.4 mAh cm−2) || LiNi0.8Co0.1Mn0.1O2 (4.0 mAh cm−2) cells to operate efficiently in a wide temperature range from −30 to 45 °C.

However, controlling the morphology and organization of lithium metal at a current collector remains a challenge and hampers the cycle lifetime of these types of batteries. Porous interlayers have the potential to guide uniform lithium plating and improve electrochemical performance. Factors such as stack pressure, interlayer composition, current density, and interlayer mechanical properties all influence lithium electrode kinetics. This study explores how these kinetic factors impact lithium movement through a porous silver–carbon (Ag-C) interlayer, lithium electrodeposits morphology, and electrochemical performance. Silver nanoparticles in interlayer can facilitate the lithium movement and induce internal stress which contributes to void formation which impedes the lithium flow. Decreasing pore sizes in the interlayer can lead to creep enhancement and preferential formation of lithium metal at the current collector. Porosity-driven creep enhancement is correlated with the formation of denser and uniform electrodes which enable greater reversible operation at lower pressures.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"11 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858055","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}

Developing high-voltage LIBs using high-capacity and high-voltage cathode materials is promising for enhancing energy density. However, conventional cathode and electrolyte materials face serious decomposition and structural degradation at high operating voltages. Herein, a dual-salts electrolyte of lithium bis(fluorosulfonyl)imide and lithium bis(trifluoromethanesulfonyl)imide(LiFSI-LiTFSI) is developed to improve the cycling stability of high-voltage lithium cobalt oxide (LiCoO2, LCO)||Li batteries. Operando X-ray diffraction analysis experiments are carried out to characterize the structural stability of cathode materials, suggesting a severe irreversible phase transformation at high voltage levels. Aging simulations, combined with experimental studies, suggest that a fast loss of active materials is mainly responsible for the capacity loss at high voltages. Carbon-coated LCO cathodes are synthesized to mitigate cycling degradation. The designed LCO||Li cells exhibit a high-capacity retention of over 85% after 400 cycles at 4 .7V. The present work provides a novel insight into understanding the degradation and enhancing the stability of high-voltage LCO-based Li-metal batteries, thus facilitating their practical applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"24 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858144","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}

Herein, methylammonium lead iodide (MAPbI3) perovskite films processed via a solvent-free laser printing technique, that exhibit exceptional stability, are reported. These films withstand extreme conditions, including high doses of X-ray radiation exceeding 200 Gy, blue laser illumination, 90% relative humidity, and thermal stress up to 80 °C for over 300 min in air. We demonstrate that laser-printed films maintain their structural integrity and optoelectronic properties even after prolonged exposure to these stressors, significantly surpassing the stability of conventionally processed films. The enhanced stability is attributed to the unique film formation mechanism and resulting defect-tolerant microstructure. These results underscore the potential of laser printing as a scalable, safe, and sustainable manufacturing route for producing stable perovskite-based devices with potential applications in diverse fields, ranging from renewable energy to large-area electronics and space exploration.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"86 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858141","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}

Transition-metal oxyhydroxides with bulk-phase OER activity of the complete material or amorphized near-surface regions are of prime application interest, but their basic electrochemical properties are insufficiently understood. Here the timescale of functional processes is clarified by time-resolved X-ray absorption spectroscopy and electrochemical impedance spectroscopy (EIS) for a thickness-series of cobalt oxyhydroxides films (about 35–550 nm). At the outer material surface, an electric double-layer is formed in microseconds followed by clearly cobalt-centered redox-state changes of the bulk material in the low millisecond domain and a slow chemical step of O2-formation, within hundreds of milliseconds. Conceptually interesting, the electrode potential likely controls the OER rate indirectly by driving the catalyst material to an increasingly oxidized state which promotes the rate-limiting chemical step. Rate constants are derived for redox chemistry and catalysis from EIS data of low-thickness catalyst films; at higher thicknesses, catalyst-internal charge transport limitations become increasingly relevant. Relations between electrochemically active surface area, double-layer capacitance, and redox (pseudo-)capacitance are discussed. These results can increase the power of EIS analyses and support knowledge-guided optimization of a broader class of OER catalyst materials.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"5 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841499","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}

Designing confined catalysts is a promising strategy to suppress HER and boost CO2ER, yet the relationship between the confined structure and catalytic performance remains unclear, limiting rational design. Herein, using Cu2O@mesoporous SiO2 core-shell catalysts as a well-defined platform, a volcano-shaped relationship is found between the thickness of mesoporous SiO2 layer and productivity of multicarbon (C2+) products in CO2 electroreduction. The optimal shell thickness of 15 nm is identified, with in situ spectroscopies and theoretical simulations attributing this to the trade-off between the local alkalinity and CO2 concentration, arising from the nanoconfinement effect. At this optimal thickness, the Cu2O@ mesoporous SiO2 catalyst achieves a C2+ Faradaic efficiency of 83.1% ± 2.5% and partial current density of 687.8 mA cm−2 in acidic electrolytes, exceeding most reported catalysts.
