In this work, a potassium 4-sulfonic-1,8-naphthalic anhydride salt (4S-NAPS), featuring dual-anchoring sites, is incorporated into the perovskite precursor. The sulfonic group (─SO<sub>3</sub><sup>−</sup>) and carbonyl group (C═O) interact with uncoordinated Pb<sup>2+</sup> ions on the perovskite surface. In addition, K⁺ ions occupy interstitial sites within the crystal lattice, thereby effectively enhancing the ion migration barrier and suppressing halide phase separation. Owing to the dual-anchoring effect of 4S-NAPS, a single-junction WBG PSC (1.68 eV) delivers a power conversion efficiency (PCE) of 22.95% and an open-circuit voltage (V<sub>OC</sub>) of 1.26 V, representing one of the highest efficiencies reported for WBG PSCs. Moreover, the unencapsulated modified devices retain 90% of initial efficiency after 3000 h in a nitrogen atmosphere, demonstrating remarkable operational stability. Notably, the fabricated monolithic PSTSC achieves a PCE of 31.20%, a V<sub>OC</sub> of 1.950 V, and exhibits negligible hysteresis. This dual-anchoring strategy provides a promising avenue for fabricating highly efficient and stable WBG PSCs and offers new insights into achieving superior performance in PSTSCs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"42 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140987","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 recent years, hydrogel electrolytes (HEs) serving as quasi-solid-state electrolytes (QEs) have been developed for AZIBs to offer a unique blend of the benefits associated with both liquid and solid-state electrolytes. This review begins by systematically outlining the challenges encountered by HEs when subjected to extreme temperature conditions, including electrolyte freezing/evaporation and dendrite growth. Subsequently, a comprehensive analysis of the recent modification strategies that have been proposed to expand the operational temperature range of HEs is conducted. In the end, multidimensional perspectives are provided for future development of wide-temperature hydrogel electrolytes (WTHEs).

Recently, antimony‐based perovskite‐inspired materials (PIMs) have emerged as promising alternatives for IPVs. However, the detailed understanding of the ion migration pathways in PIMs and their impact on device kinetics and stability remain largely unexplored. The systematic study, comparing ionic conduction in PIMs with the well‐studied LHPs, provides broader mechanistic insights into ionic conduction. This comparison highlights the correlation between ionic conduction, anomalous device behavior, and operational stability. The slower ionic conduction in PIMs, resulting from the high formation energy of halide defects, leads to weaker polarization at the interface and, consequently, higher operational stability. The higher non‐radiative recombination rate, coupled with lower ionic mobility, leads to a pronounced negative capacitance after a specific applied bias. Furthermore, first‐principles calculations explore potential ion migration pathways and their minimum activation energies in PIMs. The work therefore provides valuable insights into ion dynamics in both PIMs and LHPs, with important implications for designing novel materials and advancing future applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"99 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145116645","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}

First, the prevailing belief that lithium iron phosphate is safer than lithium nickel manganese cobalt oxide is discussed based on the general features of thermal runaway, including characteristic temperature, heat generation, mass loss, and combustion possibility. Second, the rising viewpoint that the hydrogen content in the thermal runaway of lithium iron phosphate batteries is higher than that of lithium nickel manganese cobalt oxide batteries is examined.

However, the weak interfacial interactions between dissimilar materials often hinder effective charge separation, making the establishment of a robust and well-connected interface, a significant challenge. In this study, a novel vacuum ultraviolet (VUV) irradiation-driven fragmentation technique is introduced to synthesize graphitic carbon nitride fragments (CNF). These fragments are integrated in situ with single-walled carbon nanotubes (SWNT), forming a SWNT/CNF heterojunction with optimized charge carrier dynamics and improves separation efficiency. Density functional theory (DFT) calculations demonstrate that CNF thermodynamically favors methane production by converting the *CO hydrogenation step from endothermic (pristine CN) to exothermic, thereby stabilizing the critical *CHO intermediate. The resulting SWNT/CNF heterostructure exhibits a higher specific surface area with abundant exposed active sites. The SWNT network acts as an efficient electron highway, establishing Ohmic contact that prolongs the lifetime of photogenerated carrier and suppresses recombination. Consequently, the SWNT/CNF photocatalyst achieves a methane production rate of 46.0 µmol h g<sup>−1</sup>—representing 6.0-fold and 2.5-fold increases over pristine CN and CNF, respectively, along with an apparent quantum efficiency (AQE) of 0.96% for CH<sub>4</sub> and exceptional cyclic stability.
