In this study, a halide‐based solid‐state electrolyte with a Li3InCl6 (LIC) structure is engineered through a dual‐doping strategy, which enables its application with LiCoO2 (LCO) and LiNi0.5Mn1.5O4 (LNMO) cathodes. Fluorine doping is introduced into the LIC SSE to widen its electrochemical stability window. However, this modification leads to a reduction in ionic conductivity. To address this issue, a small amount of Zr4+ is co‐doped to partially substitute In3+, which introduces lithium vacancies that facilitate Li+ diffusion and enhance ionic conductivity. The optimized composition, Li2.9In0.9Zr0.1Cl5.2F0.8 (LIZCF), exhibits the best balance of high ionic conductivity (1.37 x 10−3 S cm−1) and a wide electrochemical stability window. When applied in high‐voltage cathode‐based cells, fluorine doping is found to improve cycling stability, while Zr co‐doping effectively reduces the overpotential during operation. Furthermore, partial density of states (PDOS) calculations confirm that the dual‐doping strategy suppresses side reactions. These findings demonstrate the strong potential of the dual‐doping approach for the development of next‐generation high‐energy solid‐state battery systems.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"32 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145228909","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}

Scanning photoelectrochemical microscopy and X‐ray photoelectron spectroscopy reveal that the introduction of B into FeNiOOH facilitates internal charge transfer (electrons migrate along the direction of Ni→B→Fe) via a charge relay effect, and generates more active species (Fe3‐δ and Ni3+δ) at the BiVO4/FeNiOOH‐B/electrolyte interface, thereby accelerating both charge transfer and surface reaction dynamics. As anticipated, the BiVO4/FeNiOOH‐B photoanode achieves a remarkable photocurrent density of 6.58 mA cm−2 at 1.23 VRHE, along with excellent photostability. Furthermore, this B‐engineering effect can be applied to develop alternative TiO2/FeNiOOH‐B configurations to further enhance PEC activity.

Herein, a dual vapor‐phase treatment (DVPT) synergizing dipole self‐assembly with solvent‐induced secondary Ostwald ripening, is developed to address interfacial energy losses. Theoretical and experimental analysis reveal that gas‐phase interactions between ligands and perovskite enhance the binding strength and energy level modulation. Yet the sole application of gas‐phase passivation is demonstrated to intensify interfacial inhomogeneity and subsurface energy barriers. To mitigate this challenge, polar solvent fumigation enables spatially selective reconstruction of defective crystallites to induce planar‐depth dipolar homogenization for establishing steady‐state 3D passivation frameworks. This integrated process fundamentally reconstructs interfacial energy distribution and reorganizes subsurface crystallization, which reduces exciton binding energy and accelerates charge transfer while minimizing the quasi‐Fermi level splitting losses. Consequently, inverted 1.77 eV wide‐bandgap PSCs achieve a fill factor of 84.43% and a champion efficiency of 20.36%, surpassing state‐of‐the‐art counterparts.

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.

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.

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.

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.
