However, PSCs suffer from traps that are densely distributed at interfaces, which deteriorate the device's performance. To address this issue, a new small molecule (DTAQTPPO) capable of trap passivation on the perovskite layer surface while possessing ambipolar charge extraction properties is designed, which endow DTAQTPPO with dual functionality as both interface defect passivator and efficient hole/electron extractor in both n-i-p and p-i-n architectures. These beneficial effects improve the power conversion efficiencies (PCEs) of PSCs to 23.03% and 23.55% under 1 sun and to 37.18% and 36.29% under 1000 lux light-emitting diode (LED) indoor illuminations for both n-i-p and p-i-n architectures, respectively, after incorporating DTAQTPPO. In addition, ambipolar DTAQTPPO enhance the PV properties of PSCs using an anti-solvent-free perovskite layer with a PCE of 23.24% and indoor PCE of 35.47% under 1 sun and LED 1000 lux illumination, respectively. These results suggest that DTAQTPPO can be widely used as a multifunctional interlayer to improve the PCE of PSCs with versatile device architectures under various light illumination conditions and generality for different perovskites and processes.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"11 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857529","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, a donor-acceptor (D-A) polymer is employed to reconstruct a robust supramolecular polymer (SP) protective layer to achieve highly stable Zn anodes. The D-A polymer possessing abundant electron donor and acceptor sites can dynamically co-crosslink with water molecules and Zn2⁺ through multivalent dipole interactions (MDIs), resulting in the formation of a supramolecular polymer network. The MDIs disrupt the original strong hydrogen-bonding network within the D-A polymer, leading to the reconfiguration of polymer chain conformations and an increase in the intermolecular free volume exposing more widely distributed dipoles, thereby regulating the Zn2+ desolvation behavior and facilitating rapid and uniform Zn2+ plating. Meanwhile, the resultant supramolecular network endows the SP with an ultra-high mechanical modulus of 10.4 GPa, which can homogenize the stress distribution during the plating process for effective dendrite suppression. Consequently, the SP-assisted asymmetric cell achieves nearly 99.94% Coulombic efficiency over 9000 cycles, enabling the Zn/Zn cell to cycle for over 540 h under an ultrahigh 92% Zn utilization. Outstanding cycling stability is also successfully demonstrated in high mass-loading (≈12.8 mg cm−2) pouch cells, further demonstrating its prospects for practical applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"5 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853653","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}

Under these conditions, improving electrochemical performance necessitates accelerating the polysulfides conversion, while reducing self-discharge entails inhibiting the same conversion (disproportionation reaction, a key contributor to self-discharge). Herein, to address this challenging contradiction, an imprisoning strategy is designed that utilizes programmable solid electrolyte interphase (SEI) layers formed only on the outer surface of TiO2−x coated hollow carbon spheres (TiO2−x@C). TiO2−x@C is chosen primarily because that it supports regulated SEI growth upon simple voltage control, leveraging the different SEI formation potential on TiO2−x and C, and its conductivity and catalytic property ensure high sulfur reaction kinetics. This strategy functions effectively even under practical conditions. The exposed internal surface provides abundant effective sites and the outer SEI (as a dense barrier) prevents polysulfides from migrating out of spheres, improving the electrochemical performance. These soluble polysulfides, being confined within spheres, easily reach saturation concentrations during storage, inhibiting disproportionation reaction. Consequently, SEI wrapped TiO2−x@C/sulfur cathodes exhibit both high electrochemical performance and low self-discharge. This work is a new attempt to achieve above simultaneous optimization without performance compromise.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"29 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847035","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}

This study introduces a new research paradigm through high-throughput density functional theory (DFT) calculations to screen efficient acidic OER electrocatalysts, guided by the principle of minimizing thermodynamic free energy and optimizing the adsorption energies of OER intermediates. The incorporation of Ir increases the formation energy of oxygen vacancies and suppresses the lattice oxygen mechanism (LOM) of the RuO2, thereby enhancing its stability. In addition, Mg modulates the electronic structure of Ru and optimizes the adsorption energies of OER intermediates, thus improving the OER activity of the RuO2. Electrochemical results reveal that Mg0.23Ir0.13Ru0.64O2 exhibits a low overpotential of 191 mV at 10 mA cm−2 and superior mass activity of 338.6 A gnoble-metal−1 at 1.46 V.

Hydrogel electrolytes are regarded as promising substrates for these applications due to the ionic conductivity and safety. This work presents a quasi-solid-state electrolyte with a dual thermal insurance mechanism based on the unique structural, designed for the long-term safe operation of energy devices. The first protection involves microspheres embedded in the matrix and the hydrogel network, which initiate a dual-linkage effect and accelerate the hydrophilic-to-hydrophobic state transition in response to heat accumulation. This process rapidly closes the ion transport channels. Complementing this mechanism, water evaporation further impedes ion migration, forming the second thermal insurance. Due to the thermal reversibility of hydrogel network, the device's initial capacity can be restored upon cooling. Moreover, the regenerative behavior of electrolyte dynamically regulates matrix's water content, ensuring the recovery of ion transport capacity. Theoretical simulations and experiments demonstrate that the designed hydrogel electrolyte offers a broad and tunable temperature protection range. Notably, this thermally reversible protection can be repeated multiple times without compromising electrochemical performance, facilitating autonomous operation. The prepared hydrogels also demonstrate self-healing capabilities and mechanical flexibility, thereby enhancing the durability of self-heating protected energy storage devices.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"58 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841729","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 main challenges include high thermodynamic freezing points, slow ion diffusion, and instability at the interface under low temperatures, resulting in low energy density and poor cycle performance. Here, the role of mixing entropy ΔSmix, hydrogen bonding, and electrostatic interactions in achieving an optimal electrolyte composition is explored. By systematically varying the ethyl acetate (EA)/H2O ratio, a critical “mixing entropy optimal point” at a molar ratio of 3.91, where the electrolyte exhibits the best balance between molecular disorder and interfacial stability is identified. At this optimal point, EA molecules with polar ester group (-COO-) effectively break the hydrogen-bond network of water, enhancing the ΔSmix and lowering the freezing point to −106.95 °C. Furthermore, the stable interfacial chemistry derived from entropy-driven solvation structure effectively suppress hydrogen evolution and expand the electrochemical window to 6.2 V. Full aqueous Li-ion batteries with LiMn2O4-Li4Ti5O12 full cell delivered an initial discharge specific capacity of 135.1 mAh g−1 for 1000 cycles under rapid 10 C rate.

However, AWEs face significant challenges in electrode degradation particularly under dynamic operating conditions, induced by reverse current phenomenon during frequent startup/shutdown. Herein, this study aims to rationalize the degradation mechanisms of AWEs under these conditions. A three-electrode membrane electrode assembly (MEA) setup is first utilized to decouple polarization behaviors of anode and cathode in AWEs. Following a proposed accelerated stress testing protocol, the setup allows for tracking individual electrode performance transformations during frequent reverse current operation. Integrating operando cell studies with in situ and post-mortem characterizations, it is showed that continuous formation of highly active species, nickel (oxy)hydroxides, improves the anode performance for oxygen evolution reaction. On the contrary, irreversible oxidation of nickel to β-nickel hydroxide results in a severe degradation of cathode, leading to material dissolution, poor electrical conductivity and loss of catalytic activity for hydrogen evolution reaction. These results provide insights in nickel-based electrode transformation mechanisms for alkaline water electrolysis and indicate that cathode with higher redox reversibility can potentially improve durability of AWEs under dynamic conditions.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"26 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841727","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 review, the recent progress is examined in intermetallic compounds, particularly focusing on their structure–property-performance correlations in four critical small-molecule fuel oxidation reactions, including hydrogen oxidation reactions, formic acid oxidation reactions, methanol oxidation reactions, and ethanol oxidation reactions. These reactions are central to sustainable fuel-cell technologies due to their high theoretical energy densities, relatively benign byproducts, and scalability for clean energy production. This review begins by highlighting the advantages of intermetallic compound nanocrystals over metal alloys, such as their unique crystal structures, exceptional thermodynamic stability, enhanced durability, improved intrinsic activity, optimized distribution of active sites, and benign scalability.
