Achieving interfacial compatibility between the continuously advancing SSEs and cathode active materials (CAMs) is crucial for the realization of advanced ASSBs. Recently, the emergence of interface-compatible dual-conductive (ICDC) cathodes has opened a novel pathway towards developing ASSBs with high energy density and cost efficiency. The ICDC cathode refers to a single cathode material engineered to simultaneously achieve mixed ionic-electronic conductivity while ensuring good compatibility with SSEs in ASSBs. This innovative research topic has been propelled by the ongoing evolution of SSEs. In this minireview, we first discuss the progress in the mutual enhancement of SSEs and cathode materials, with a focus on addressing interface compatibility and dual conductivity challenges faced by conventional layered oxide CAMs in advanced sulfide- or halide-based ASSBs. Then, we outline two primary approaches for achieving ICDC cathodes: sulfurization and halogenation. Finally, we present an outlook, highlighting unresolved questions and future research directions. This minireview serves not only a summary of advancements in ICDC cathodes, but also a fundamental guidance to inspire further exploration for cathode materials integrated with the state-of-the-art SSEs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"26 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177123","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, we demonstrate an efficient ionic potential modulation strategy to produce a lattice-stable layered oxide with favorable Na+ diffusion kinetics via selective introduction of cations with different ionic potentials into transition metal (TM) layers and Na layers of layered oxides. In contrast to the implantation of cations with high ionic potentials (Φ > 28.99 nm−1), introducing cations with low ionic potentials (e.g., Li+, 13.16 nm−1) into TM layers enables to facilitate the delocalization of electron clouds around lattice O2− towards TM ions, thereby constructing a unique O-TM-O interlocking configuration to simultaneously improve the stability of TM ions and lattice O2−. Meanwhile, the incorporation of cations with low ionic potentials such as K+ (7.25 nm−1) into Na layers (Na+, 9.80 nm−1) induces an attenuated K+-Na+ electrostatic interaction, thus diminishing the repulsion during Na+ diffusion process. These unique features not only strengthen the skeletal structure of TM layers, but also promote the Na+ interlayer diffusion. Consequently, an excellent rate performance of 78.7 mAh g−1 at 50 C and a long-term stability up to 2000 cycles are achieved in SIBs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"27 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177124","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}

While alkaline CO2 electrolyzers suffer from low CO2 utilization due to cathodic carbonate formation and crossover, acidic CO2 electrolyzers suffer from low CO faradaic efficiency. Reverse-bias Bipolar Membrane (BPM) cell architectures have been proposed to promote cathodic proton transport, yet resulted in limited cell lifetimes due to complex degradation and failure regimes. A thorough diagnosis of BPM cell dynamics is missing to date. Here, we build and diagnose an efficient zero-gap reverse-bias BPM CO2-to-CO electrolyzer cell deploying CO-selective single Ni atom cathode catalysts. We analyzed its key cell performance parameters and diagnosed the cell stability and failure regimes over 100 hours. The electrolyzer cell showed excellent performance up to 500 mA cm-2 with CO faradaic efficiency near 100 %. The proton-controlled ion transport in the cathode was directly confirmed by an experimental carbon cross-over coefficient (CCC) of zero, suggesting minimal carbon loss due to carbonate formation. This was coupled to a high single pass conversion of ~70% at the largest current densities and 60 vol% CO in the cell outlet, ideally suited for process cascade involving electro- or thermal catalytic steps. While use of a N2 bleed for internal reference has been known to be critical for accurate evaluation of cell performance, we now propose the experimental N2 vol% in the combined cell outlet and bleed flow to be also a valuable diagnostic tool to recognize and analyze cell failure regimes.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"33 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165516","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}

Moreover, the stability of ZIBs under extreme operating conditions remains a critical yet often overlooked issue. Here, we present a novel silane-decorated glass fiber separator with engineered physical structures and surface chemistry, facilitating highly reversible and ultra-reliable ZIBs. Silane strengthens the separator, resists stress, and forms heat-insulating char layers under flame, ensuring reliability in extreme conditions. Silane networks also function as fillers that enhance pore uniformity for even Zn2+ flux. The amino groups in silane demonstrate comprehensive management of interfacial anions, cations, water transfer and reaction kinetics. This capability induces Zn2+ to concentrate at the interface, accelerates Zn2+ transfer, reduces deposition barriers, and obstructs water molecules and sulfate ions from participating in parasitic reactions. Consequently, dendrite-free Zn plating/stripping is achieved with 99.4% Coulombic efficiency over 250 cycles, stable charge/discharge performance for 7000 hours, and remarkable cycling stability and flame resistance for Zn//V full batteries. This strategy demonstrates versatility across various separator materials and battery chemistry, offering a promising route to more reliable and higher-performing energy storage systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"60 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165515","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}
