This review provides a comprehensive analysis of the design principles and mechanisms of hydrogel electrolytes for enhancing the electrochemical long‐cycle stability of AZIBs. Hydrogel electrolytes are first compared with traditional aqueous liquid electrolytes, emphasizing their advantages in ion transport regulation, mechanical compliance, and interface compatibility. Key performance parameters—including ionic conductivity, Zn2+ transference number, crystallographic selectivity, and solid electrolyte interphase (SEI) composition—are discussed in relation to hydrogel composition and structure. Based on the essential components of hydrogel systems (hydrophilic polymers, water, and zinc salts), various modification strategies are systematically classified and analyzed, such as polymer backbone engineering, water activity regulation, and Zn2+ solvation environment tailoring. Emerging design concepts are also highlighted, including gradient architectures, dynamic crosslinking, and dual‐network architectures, which contribute to improved mechanical integrity and dendrite suppression during extended cycling. Finally, current challenges are outlined and future directions are proposed in the rational design and functionalization of hydrogel electrolytes to meet the demands of next‐generation energy storage systems, particularly in grid‐scale applications and flexible/wearable electronics.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"13 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215815","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}

The prerequisite for its industrialization on a terawatt scale is the exploitation of an electrocatalyst that can operate steadily at current densities exceeding ampere levels. In this work, a Ni‐O(OH)‐C electrocatalyst consisting of an unsaturated Ni‐O(OH) immobilized Ni crystal confined by carbon layers is proposed to realize the exceptional performance at the ampere‐level current densities toward ethanol electrooxidation to acetic acid (EOR), hydrogen evolution reaction (HER), and their integrated system. This catalyst achieves a current density of 1 A cm−2 for EOR and HER at a potential of 1.46 and −0.3 V (vs RHE), respectively. The unsaturated Ni‐O(OH) species confined by carbon layers offer an optimized electronic structure and interfacial microenvironment to facilitate the HER kinetics, and they can deliver the electrophilic adsorbed oxygen to induce the EOR and block its unfavorable structural transformations during electrocatalysis. A Ni‐O(OH)‐C catalytic HER||EOR integration system offers a 220 mV voltage reduction at 1 A cm−2 in comparison to that of Pt/C||RuO2 water electrolysis cell. A Zn‐ethanol‐air battery is equipped with a Ni‐O(OH)‐C catalyst, exhibiting >500 h of stable operation.

Key aspects such as the handling of the perovskite solution, the air jet used for drying, or the process atmosphere are often incompletely specified. In response, this review systematically presents the empirical evidence linking process parameters to the film morphology and the device performance for solution-based one-step and two-step deposition routines of highly efficient PSCs as well as large-area perovskite modules. To maximize interdisciplinary understanding, the process parameters are standardized within the thin-film solar cell ontology (TFSCO), structured according to the internal logic of sequential deposition and classified by fundamental mass transfer mechanisms.

These NFAs exhibit an A2–D–A1–D–A2 molecular architecture and are synthesized through efficient methods.

Binary OSCs using D18 as donor achieved power conversion efficiencies (PCEs) of 10.23% (LM‐T), 12.25% (LM‐F), and 13.84% (LM‐Se), with LM‐Se showing superior performance due to broader absorption, lower exciton binding energy, and enhanced charge transport. Incorporating LM‐Se into a ternary blend with D18 and Y6 ((D18:LM‐Se:Y6 1:0.4:0.8) further improved the PCE to 17.53%, outperforming the binary D18:Y6 device (15.12%).

However, Sb2(S,Se)3 films deposited via the conventional hydrothermal method fail to achieve desirable optoelectronic properties and crystallinity, which ultimately hinders their applications in photovoltaic devices. In this study, an innovative post-treatment process is developed, wherein the Sb2(S,Se)3 absorber is soaked in a mixed aqueous solution containing ammonia, sodium citrate, and cadmium sulfate, followed by annealing, resulting in multi-dimensional optimization. It is revealed that the synergistic interaction in this strategy leads to the formation of cadmium selenide and cadmium sulfide on the surface and the infiltration of cadmium ions into the bulk phase. This outcome finally optimizes the atomic structure by passivating the deep-level defects such as Se and S vacancy, while also increasing the crystallinity through a strong chemical bonding effect. Furthermore, the slight etching of the surface by ammonia reduces the content of antimony oxide, increases phase purity, and optimizes interfacial contact in the device, thereby facilitating carrier transport. With these advantages, a high power conversion efficiency of 10.5% for Sb2(S,Se)3 solar cell is achieved.

Herein, a novel mechanical-thermal co-design strategy is proposed based on a solid-liquid electrode configuration to address this critical issue. This approach introduces a gravity-assisted controllable encapsulation method that enables thin-layer elastic confinement of liquid metal electrodes, simultaneously minimizing parasitic thermal resistance and achieving exceptional stretchability. Additionally, a tight-binding arrangement of thermoelectric pairs mitigates interfacial stress concentration during mechanical deformation to significantly improve stretchability, while microstructured solid electrodes enhance heat dissipation to boost output power. The optimized device achieves over 100% stretchability (device resistance change does not exceed 10%) and a normalized output power density of 0.098 µW cm−2 K−2 under natural convection conditions without external heat sinks, with excellent stability maintained after over 10 000 cycles under large tensile and bending strains. As a proof of concept, the efficient applications of the FTEDs are demonstrated in harvesting heat from curved surfaces in various scenarios and powering LED bulbs.

The unique mission profile of electric Vertical Take-off and Landing (eVTOL) aircraft necessitates a focused investigation into the thermal behavior and safety characteristics of these batteries. In this study, operando isothermal microcalorimetry is employed to examine the thermal evolution of Li-ion batteries under cycling conditions representative of eVTOL operations. These findings reveal that high-power discharge events—such as those during take-off and landing—shift the thermal response toward exothermic behavior, in contrast to the typically endothermic response expected under near-equilibrium cycling conditions. Additionally, the results suggest that advanced electrolyte formulations may help suppress excess heat generation, thereby improving battery safety. Notably, the calorimetric results exhibit a distinct thermal signature associated with lithium plating, offering a potential diagnostic for detecting Li plating during eVTOL operation. Overall, this study demonstrates the utility of isothermal microcalorimetry as a valuable tool for assessing thermal risks in Li-ion batteries for eVTOL applications, and highlights the importance of targeted design strategies to mitigate safety hazards during high-power demand scenarios.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"120 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209383","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, the interplay between the dissolved Mn2+ and the solid electrolyte interphases (SEI) on graphite anode is revealed by different characterization techniques, such as Raman spectroscopy, cryogenic transmission electron microscopy, electron energy loss spectroscopy, and time‐of‐flight secondary ion mass spectrometry. The results demonstrate that Mn2+ is inclined to coordinate with ethylene carbonate (EC), which is easily decomposed and generates organic‐Mn2+ species and gaseous byproducts.

To overcome this, a phosphonium‐based ionic liquid, allyl trimethyl phosphonium bis(trifluoromethane)sulfonimide (APT), is introduced as a multifunctional electrolyte additive. APT forms a eutectic mixture with EC, effectively lowering the freezing point and viscosity while enhancing ionic conductivity at low temperatures. Furthermore, APT weakens the Li⁺–EC interaction, facilitating more efficient Li⁺ desolvation at the graphite interface, and promotes the formation of a thin, uniform, LiF‐rich solid electrolyte interphase on the graphite anode, leading to the fast interfacial Li⁺ transfer kinetics.
