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. The results provide a promising thermodynamic foundation for designing high-performance aqueous electrolytes, with implications for next-generation low-temperature aqueous lithium-ion batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"1 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841732","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, 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}

Recent progress of different direct recycling methods for retired power batteries (LiFePO4, LiCoO2, LiNixCoyMnzO2) are outlined, the progress of pretreatment and removal of impurities are also summarized, emphasizing the importance of improving the technical stability of direct recycling of retired LIBs.

Existing reviews have primarily focused on intermetallic compounds for specific electrocatalytic reactions or their synthesis strategies, while a comprehensive perspective on how ordered structures contribute to performance across different electrochemical applications that share similarity remains underexplored. 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. Subsequently, their applications in these small-molecule fuel oxidation reactions are comprehensively discussed in detail.

This mini-review summarizes recent advances in computational methods, particularly the integration of density functional theory (DFT) with machine learning (ML), to accelerate the rational design of electrocatalysts by enabling rapid screening and structure-training predictions. Meanwhile, the optimization strategies of carbon-based electrocatalysts are systematically investigated, focusing on four key aspects: atomic-level heterochromatic doping, defect engineering, microenvironment control, and morphological design.

Current thermoelectric cooling devices rely on advanced Bi2Te3 alloys. However, the scarcity of the Te element raises the price of thermoelectric devices and limits their widespread use. Therefore, developing high-performance, low-cost thermoelectric materials is a key focus in the field. In this work, a high-performance n-type PbSe crystal is developed through lattice plainification and physical vapor deposition. Adding trace amounts of Sn is found to compensate for intrinsic Pb vacancies, which effectively improves the crystal quality and significantly enhances the electron mobility from 1125 to 1550 cm2 V−1 s−1. This results in a high power factor of 37 µW cm−1 K−2 at room temperature for PbSe crystal, transforming this traditional mid-temperature power generation thermoelectric material into a solid-state refrigeration material. The 7-pairs PbSe-based module achieves a temperature difference of 52 K at room temperature, demonstrating a competitive coefficient of performance (COP) of 3.5 under 5 K cooling conditions. Single-leg efficiency tests also validate a 4.5% conversion efficiency at Th = 773 K for the material.

However, it remains challenging to achieve the controllable fabrication of high-quality perovskite films over large areas. Herein, a ternary solvent system composed of 2-methoxyethanol (2ME), N,N-dimethylformamide (DMF), and N-methyl-2-pyrrolidone (NMP), is thoroughly investigated to fine-tune the solubility, volatility, and coordination characteristics for formamidinium cesium (FACs) perovskite precursor solution. Initially, 2ME and DMF are employed to adjust the volatility and their coordination of Pb2+ ions, thereby regulating perovskite nucleation rate. Following this, NMP is introduced as a chelating agent to facilitate the formation of stable intermediate phase, which could extend the processing time window for the solution coating and facilitate crystal growth in the subsequent annealing process. With the optimized solvent system, high-quality, large-area FACs perovskite films are successfully fabricated.
