Here, we report an all-molecular-ferroelectric composite electrolyte in which imidazolium perchlorate (ImClO4), a small organic molecular ferroelectric, is introduced into a ferroelectric poly(vinylidene fluoride-co-hexafluoropropylene) (PVH) matrix. ImClO4 not only promotes lithium-salt dissociation through strong spontaneous polarization and high dielectric response, but also reconfigures the lithium-ion solvation shell via competitive coordination of ClO4−. As a result, the optimized PVH–ImClO4 (PVH–IC) electrolyte delivers a remarkably high room-temperature ionic conductivity of 1.11 × 10−3 S cm−1 and a high lithium-ion transference number of 0.72, together with ultrastable Li plating/stripping for over 10 000 h. When paired with a nickel-rich NCM811 cathode, PVH–IC enables solid-state full cells with excellent rate capability (126.6 mAh g−1 at 10C) and long-term cyclability, achieving 73% capacity retention at 5C after 1000 cycles. PVH–IC also demonstrates outstanding performance under high-loading cathodes, ultrathin electrolyte films, and pouch cells. Mechanistic studies further reveal homogenized lithium-ion flux and stabilized electrode interphases in PVH–IC during cell operation. More broadly, this work identifies molecular ferroelectrics as a new class of multifunctional regulators that break the conductivity–transference trade-off and open a general route to next-generation solid-state batteries.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"385 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853660","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, we propose an asymmetric interfacial activation (AIA) framework to address this contradiction by thermodynamically decoupling the redox activation windows of the cathode and anode. Guided by high-throughput density functional theory screening, difluorophosphate (DFP-) is identified as a molecularly precise asymmetric additive that satisfies dual thermodynamic criteria. DFP- operates via a dual, interface-specific pathway, whereby it selectively undergoes sacrificial oxidation to construct a dense, NaF-rich cathode electrolyte interphase (CEI), while remaining electrochemically inert at the HC anode, and suppressing solvent reduction by modulating local solvation. This tailored interfacial chemistry enables excellent cycling stability of the Na3V2(PO4)2F3|HC full cells within the voltage window of 2-4.3 V and also applicable to practical pouch formats, achieving 4.3 Ah-level NFM111|HC cell operation with an energy density of 190.4 Wh kg-1.

Nevertheless, the vast compositional space inherent in these systems frequently obscures the formulation of universal design rules and precise structure–performance correlations. This review systematically evaluates the compositional design principles and compatibility limits of high-entropy electrode and electrolyte materials, respectively tracking the solid-state phase stability and the liquid-state solvation regulation from coupled thermodynamic and kinetic perspectives. We clarify that solid HEMs require compositional compatibility to form phase-pure single-solid-solution frameworks, whereas liquid HEMs require solvent–solute compatibility to maintain homogeneous solutions by balancing miscibility, salt dissolution/dissociation, and competitive solvation. Moreover, by bridging the four core effects—high entropy, lattice distortion, sluggish diffusion, and the cocktail effect—and initial compositional selection with terminal electrochemical performance, this review underscores the transformative impact of high entropy on enhancing initial Coulombic efficiency, capacity, cycling stability, and rate capability. The work concludes by identifying persistent bottlenecks and prospective research avenues to catalyze further breakthroughs in HEMs for advanced energy storage technologies.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"18 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853662","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 particular, achieving homogeneous deposition of oxide electron transport layers (ETLs) on textured substrates remains a longstanding challenge. Here, we identify that SnO2, a widely used ETL, exhibits pronounced in-plane heterogeneity in the Sn2+/Sn4+ valence distribution. The resulting energetic disorder intensifies non-radiative recombination at the buried interface, constituting a key limitation for further performance improvement, particularly upon upscaling. To address this issue, we propose an in-plane homogenization bridging strategy by introducing a robust molecular interlayer of 1,4-phenylenebis(phosphonic acid) (PBA) on the FTO substrate. This strategy transforms the conventional electrostatic adsorption-driven deposition of SnO2 into a PBA-bridged binding-mediated anchoring process, wherein the PBA layer establishes chemically homogeneous and directionally coordinated anchoring sites for SnO2 nanoparticle assembly. Consequently, the valence-state inhomogeneity inherent to conventionally deposited SnO2 ETLs is effectively suppressed, resulting in a spatially uniform electronic structure across large-area substrates and suppresses energetic disorder at the buried interface. The resulting ETL delivers a PCE of 27.04% for 0.061 cm2 devices, 25.92% for 1 cm2 devices (certified steady-state PCE of 25.71%, 25.85% in reverse scan) and 23.56% for 5 × 5 cm2 modules with a 16.02 cm2 aperture area. This work links microscopic valence-state distribution to device performance and provides a scalable route to electrically homogeneous charge transport layers in perovskite photovoltaics.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"70 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853613","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, we report the electrochemical synthesis of an all-fluorinated interphase with an ultrahigh fluorine content over 50 at%, composed of a gradient organofluorine matrix (–CF2– and –CF3) and inorganic fluoride (ZnF2), through zinc-mediated electrochemical reduction of zinc perfluorotetradecanoate. During the reduction process, C–F bonds are cleaved to form inorganic ZnF2 near the electrode surface, while a hydrophobic residual layer is retained on the electrolyte-facing side. Moreover, this outer residual layer serves as a reservoir of fluorinated precursors that can locally regenerate ZnF2 at newly exposed Zn sites, thereby imparting a self-healing function. Benefiting from these features, the all-fluorinated interphase enables stable symmetric-cell cycling for over 4200 h at 5 mA cm−2 and 1 mAh cm−2, a high Coulombic efficiency of 99.82% over 7250 cycles, and high-capacity Zn deposition exceeding 100 mAh cm−2.

The central challenge is identifying window states that minimize building energy consumption across varying conditions. Prevalent controls operate states at environmental thresholds rather than at energy levels, which can even cause net energy increases. Here, we establish an absolute-zero-energy paradigm by conducting full-year (8760 h) recursive energy minimization across over 10 million simulations. It determines the ideal energy-saving potential and transmittance targets for dynamic windows and generates hourly minimum-energy schemes from the available states of an electrochromic window. Across globally representative climates, electrochromic windows under rule-based control may exhibit higher energy consumption than normal windows, with lighting penalties that can exceed the corresponding HVAC savings. This paradigm nearly eliminates lighting penalties and amplifies HVAC savings, delivering a 2.06–11.41% gain in total energy-saving rate and CO2 mitigation of 0.69–8.41 kg m−2 of floor area, with a maximum enhancement exceeding 28-fold.

The power cloak integrates a large-area mechanical energy harvesting ribbon array, a coplanar energy-harvesting microgrid, and a low-power selfadaptive energy management circuit onto a textile substrate. The inter-unit coupling of ribbon array doubles the transferred charge (up to 0.96 mC m -2 ) while the microgrid and management circuit enable human-size integration by eliminating phase discrepancies and suppressing impedance-mismatch dissipation, respectively. With an average power density of 1.78 W m -2 and energy conversion efficiency over 15%, the power cloak can meet diverse emergency power supply needs in extreme environments, such as lighting display, electric heating for thermal insulation, electrochromic camouflage, rescue communication, and GPS positioning.

Current high-performing cathodes mostly rely on Ba and Co to achieve sufficient catalytic activity, but these elements often cause poor chemical stability and thermal expansion mismatch with the electrolyte. Herein, we propose a completely Ba- and Co-free cathode for H-SOFCs that delivers a record peak power density of 2739 mW cm−2 at 700 °C. This performance not only surpasses all reported Ba/Co-free cathodes but also exceeds that of the majority of Ba/Co-containing counterparts. The cathode features an inverted bilayer structure, consisting of a pure La0.8Sr0.2Sc0.5Fe0.5O3−δ (LSSF) layer in direct contact with the electrolyte and a LSSF + Y0.5Bi1.5O3−δ (YSB) composite layer on top. The LSSF interlayer provides intrinsic cathode catalytic activity and proton migration channels, while effectively suppressing the severe reaction between YSB and the electrolyte. This design integrates the reactive but highly conductive YSB into H-SOFCs and fully exploits its high oxygen-ion conductivity in the cathode. Furthermore, defect-rich YSB (DR-YSB) obtained via the ultrafast high-temperature sintering (UHS) method doubles the oxygen diffusion and surface exchange coefficients compared to pristine YSB, further enhancing cathode and fuel cell performance. Moreover, the completely Ba/Co-free composition endows the cathode with excellent chemical stability and thermal expansion matching with the electrolyte, leading to outstanding long-term stability and thermal cycling capability. This work establishes a new benchmark for high-performance H-SOFC cathodes and provides an interesting strategy to overcome compatibility-driven bottlenecks in next-generation electrochemical devices.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"5 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853658","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}

Secondary and unconventional feedstocks—including coal ash, bauxite residue, phosphogypsum, acid mine drainage solids, and end-of-life materials—offer a pathway to diversify supply, but their ability to contribute meaningfully at scale remains uncertain. This Perspective examines REE recovery through a feedstock–process–scale framework, emphasizing that viability is governed not by individual technologies alone, but by the interaction between feedstock characteristics, separation constraints, and system-level design. We evaluate conventional and emerging recovery pathways—including hydrometallurgical processing, solvent extraction, bioleaching, deep eutectic solvents, electrochemical approaches, and protein-based separations—highlighting a consistent trade-off between selectivity, reagent intensity, and scalability. Across feedstocks, a fundamental tension emerges between volume and process complexity, limiting the extent to which secondary resources can displace primary supply. We identify key barriers to industrial deployment, including impurity management, separation challenges, and process integration, and assess their implications for techno-economic and environmental performance. Finally, we outline priorities for advancing scalable REE recovery, including hybrid flowsheets, improved separation strategies, data-driven optimization, and policy mechanisms to support deployment. Together, these insights provide a framework for evaluating which recovery pathways are likely to transition from laboratory demonstration to meaningful contribution in future REE supply chains.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"18 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853573","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}
