However, its practical application is limited because of concerns about product purity, energy efficiency, and cost competitiveness. Here, we report an acid shuttling strategy to enable energy-efficient production of H2O2 in a porous solid electrolyte (PSE) reactor. This strategy allows acid to serve as a proton reservoir to facilitate the reaction equilibrium (H+ + HO2− → H2O2) in the PSE chamber. Meanwhile, it regenerates acid at the anode, maintaining the high purity of the H2O2 stream. Compared to the system without acid shuttling, the cell current density is improved by over sixfold at a cell voltage of 2 V while the specific energy consumption for H2O2 production is reduced by 53%. H2O2 is produced with high purity and a concentration of up to 19.1 wt%, which is among the highest values reported to date. Moreover, the consumed acid is regenerated through anion migration to the anode with a recovery ratio of up to 99.8%, realizing a closed loop with nearly zero net consumption of acid. This study provides a cost-effective strategy for producing H2O2 in a decentralized way.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"376 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148915206","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}

Although salt anion-coordination species offer a high thermodynamic propensity for generating a robust LiF-rich solid electrolyte interphase (SEI), their kinetic propensity is diminished by the electromigration-induced concentration gradient, especially at low temperatures. Herein, we verify this concentration gradient in WSE systems and develop a weakly solvating microemulsion electrolyte (WSME) to enable interfacial stabilization in low-temperature LMBs. Driven by liquid-liquid interfacial tension, the fluorinated micelles in the WSME spontaneously migrate toward the electrode interfaces and participate in interphase formation. This process offsets the unfavorable concentration gradient to generate a LiF-rich SEI at the negatrode, while concurrently constructing a LiF-rich interphase at the positrode. Benefiting from the dual-interfacial stability, LMBs exhibit improved cycling performance at low temperatures. Li||Li and Li||Cu cells sustain stable cycling for 7500 h and 1600 cycles at −20 °C, respectively. 4.5 V Li||LiNi0.8Mn0.1Co0.1O2 (NMC811) cells exhibit outstanding cycling performance at −20 °C (1600 cycles with 87% retention) and −40 °C (300 cycles with ~100% retention).

Bubble accumulation disrupts catalyst layer microenvironment, inducing severe transport losses and operational instability. Here we establish ionomer molecular architecture as an active engineering parameter that governs bubble nucleation, adhesion and detachment within practical catalyst layers. Rigid, intrinsically microporous poly(aryl piperidinium) ionomers suppress catalyst encapsulation while forming hydrophilic, interconnected transport pathways that promote dense nucleation of nanoscale bubbles, reduced interfacial adhesion and accelerated detachment without mesoscale electrode restructuring. Multiscale in situ visualization directly correlates ionomer structure with bubble statistics from nano- to microscale, revealing pronounced suppression of transport overpotential. When implemented in AEMWEs, adhesion-regulated bubble detachment enables current densities up to 8.26 A cm-2 at 2.0 V and sustains operation for over 1100 h at 2 A cm-2 and 80 oC, while maintaining transport stability upon scaling to 25 cm2 membrane electrode assemblies. More broadly, regulating adhesion-mediated bubble detachment establishes a molecular design principle for stabilizing interfacial gas transport in electrochemical energy-conversion systems. Ionomer microenvironment engineering therefore provides a scalable pathway toward transport-stable, high-rate water electrolysis and other gas-evolving electrochemical technologies.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"79 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148908815","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}

This challenge originates from both (i) inhomogeneous nucleation at the electrolyte–electrode (EE) interface within separator pores, and (ii) aggravated Zn propagation along the separator pore walls at the electrolyte–separator–electrode (ESE) three-phase interface. Here we propose a dual-interface strategy that combines propylene glycol monomethyl ether (PM) as a co-solvent with a negatively charged sulfonated separator to tailor both interfaces and achieve uniform Zn plating. PM regulates the Zn2+ solvation sheath and preferentially adsorbs at the Zn surface, enabling homogeneous nucleation at the EE interface. Concurrently, negatively charged -SO3− groups anchored on the micrometer-scale porous separator homogenize the local electric field and Zn2+-ion flux at the ESE interface, effectively mitigating the separator-induced “step effect” and guiding uniform deposition with preferential Zn(002)-orientation. This synergistic design enables a Zn||Zn symmetric cell to cycle stably for 2000 h at a practical areal capacity of 5 mAh cm-2 and a Zn||Cu half-cell to deliver an average Coulombic efficiency of 99.8% over 1000 h. Remarkably, a 90 cm2 Zn||Zn0.14V2O5·nH2O pouch cell delivers 1.07 Ah and retains 92.2% capacity after 300 cycles. These results underscore the critical role of the dual-interface engineering in achieving uniform Zn deposition under practical operation and provide a scalable pathway toward durable, high-performance zinc-ion batteries.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"7 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148908816","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}

This approach enables tunable phase distribution between amorphous and crystalline regions across both room and elevated temperature, achieving compressed free volume in the amorphous domains at room temperature while promoting chain folding within crystalline lamellae at high temperature. The resulting structural integration reinforces the crystalline-amorphous interface, effectively suppressing charge transport and space-charge accumulation under high electric fields, and leads to significantly improved dielectric breakdown strength. The developed material achieves unprecedented discharged energy densities of 11.7 J cm -3 at 30°C and 6.4 J cm -3 at 125°C, while maintaining discharge efficiencies above 90% and 81%, respectively, surpassing all previously reported PP-based dielectrics.

Nevertheless, their functions are often interpreted through limited and isolated descriptors, leaving broader mechanisms insufficiently explored. In this perspective, we view hydrogel electrolytes as dynamic electro-chemo-mechanical media and develop a mechanistic framework spanning both bulk electrolytes and electrode–electrolyte interfaces. Beyond summarizing specific material designs or battery chemistries, we examine both well-established and underexplored general mechanisms, while drawing on mechanistic insights from related fields to identify potentially overlooked contributions and formulate new hypotheses that may be relevant to hydrogel electrolytes.

Bismuth-based catalysts are highly selective for this conversion, but suffer from limited mass transport and uncontrollable reconstruction. Herein, we harness reconstruction to predictively design an advanced core-shell nanowires pre-catalyst, in which bismuth oxyformate (BiOCOOH) nanowires are encapsulated by a hydrophobic polypyrrole (PPy) layer. During the reductive eCO2RR process, BiOCOOH is spontaneously reduced to metallic Bi and reassembles inside the PPy shell, preserving the nanowire morphology while creating a void structure between Bi and PPy due to volume shrinkage. This configuration not only suppresses morphology changes and active-site leaching during electrochemical reconstruction, but also promotes efficient CO2 and proton transfer through reconstruction-induced voids. Consequently, the catalyst delivers exceptional eCO₂RR performance in both H-type and flow cells, achieving formate selectivity exceeding 90% and a maximum formate partial current density of 511 mA cm−2. Importantly, it shows remarkable long-term durability of 614 h at combined current densities of 20 and 200 mA cm−2, as well as 241 h at an industrial-level current density of 500 mA cm−2.
