However, the low stability of the anode interface, including both the morphology of Li metal and the solid electrolyte interphase (SEI), hinders the practical battery implementation and creates safety concerns. In this work, sulfolane-based localized high-concentration electrolyte (LHCE) is applied as a sustainable and applicable electrolyte for anode-free Li-metal batteries (AFLMBs). The effects of important factors, including type of anode current collector, electrolyte properties, and cycling conditions, are explored in terms of clarifying their impact on the structural and functional properties of LFP‖Cu cells. Flammability tests indicate that the electrolyte is nonflammable by direct ignition under the applied conditions, which is highly beneficial for the safety and sustainability of the AFLMB. The performance of SL-based LHCE is tested for Li plating–stripping reaction on Cu-engineered substrates, where the microporous Cu substrates display major improvement, which can be attributed to their enlarged active surface area and open and highly interconnected porous structure. The influence of the key operation parameters, state of charge, depth of discharge, and current density is explored, and useful correlations of these factors with the anode structural properties and battery cycling stability are established.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202500943","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147585107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequently, the powders are functionalized with a ZnO protective coating through a wet-chemical approach employing zinc acetate in ethanol. Structural characterization confirmed that the ZnO layer maintained the P2-type (P63/mmc) structure, while energy-dispersive X-ray spectrometry mapping verified the successful coating. Electrochemical analyses, including electrochemical impedance spectroscopy (EIS) and cyclic voltammetry, revealed that although the redox reaction mechanism remained unchanged, the charge–transfer resistance (Rct) depended on the coating thickness. ZnO-coated NMFO electrodes exhibited initial discharge capacities of 159.3, 153.6, and 124.8 mAh g−1 with respective capacity retentions of 48.9%, 41.9%, and 52.0% after 100 cycles for ZnO contents of 0.2, 0.4, and 0.6 wt.%. The galvanostatic intermittent titration technique results indicated that the diffusion coefficients varied with the coating conditions. Operando EIS from 1.5 to 4.3 V showed stable bulk resistance (Rb) but voltage-dependent variations in solid electrolyte interface resistance (RSEI) and Rct. Additionally, sodium azide is used to presodiate the hard carbon (HC) anode to enhance the full-cell performance. The ZnO-coated cathode paired with NaN3 presodiated HC delivered a capacity of over 120 mAh g−1 at C/10. Ex situ analysis after 500 cycles confirmed structural stability, demonstrating that ZnO coating and NaN3 presodiation collectively improve sodium-ion battery performance.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, knowledge of the heat release within the battery is a key parameter. In this work, a methodology is investigated for determining the reversible heat release based on continuous quasi-open-circuit-voltage (qOCV) measurements, which is not yet fully established in the literature. Three key factors influencing the evaluation of the entropic heat coefficient are presented and it is discussed in detail how these should be taken into account for the first time. The entropic coefficients derived from the continuous approach are compared with values obtained from potentiometric measurements of the same pouch cell and show a high level of accuracy for the continuous qOCV method. The standard battery cycler is used, with a measuring uncertainty of 1 mV, yields results that are in very good agreement with the broad spectrum of literature values, obtained using different methodologies and uncertainties. The validity and robustness of the approach are further demonstrated by applying the continuous method to data from a different automotive prismatic cell with a significantly different testing procedure.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202500468","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these membranes often have poor conductivity. The modification of N-alkylation of benzimidazole unit improves the conductivity of membranes, which are mostly found in alkaline water electrolysis and fuel cells. Only a few membranes are incorporated in vanadium redox flow battery (VRFB). Herein, a new class of polyimidazolium-knitted PBI-based membranes are synthesized via de novo approach using 3,3′-diaminobenzidine and 4,4′-biphenyldicarboxylic acid with infused grafting of halato-telechelic poly(vinyl imidazolium) (PVIm) for VRFB. As evidenced, the PVIm-grafted membranes show increase in the electrochemical properties. OPBI-VIm-x demonstrates improved water uptake attributes and bulk ion conductivities compared to Nafion-212 (N-212). Further, OPBI-VIm-x membranes are assessed based on several key parameters like vanadium crossover, ion selectivity, and vanadium single-cell setup. Among them, OPBI-VIm-1.25 achieves lowest vanadium permeability and highest ion selectivity with maximum single-cell performance (Coulombic efficiency ≈98%, voltage efficiency ≈71%, and energy efficiency ≈70%) with stable cycling up to 300 cycles. As evidence, a promising strategy to address limitations of traditional OPBI involves the functional tethering of stable poly-cationic moieties, which enhance hydrophilicity while preserving the inherent thermal and chemical stability of pristine PBI membranes.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrochemical and structural performance of the green-synthesized NMC (GS-NMC) is systematically compared with NMCs prepared using sol–gel and solid-state methods. Structural and surface analyses show that GS-NMC possesses a highly ordered layered structure with minimal cation mixing, improved crystallinity, and increased surface area. Electron microscopy and Brunauer–Emmett–Teller analyses confirm a refined nanoscale morphology with well-developed porosity. The X-ray photoelectron spectroscopy results indicate reduced surface impurities and an optimal distribution of transition-metal oxides. Electrochemical testing in a three-electrode aqueous LiOH system demonstrates that GS-NMC achieves enhanced surface redox activity, low interfacial resistance, and stable pseudocapacitive behavior (≈120 mAh g−1 within a ±1.0 V window) over 1000 cycles. In comparison, sol–gel and solid-state samples exhibit higher polarization and faster capacity fading. Although tested under aqueous half-cell conditions, the results show that green synthesis offers a promising route to produce structurally robust and electrochemically responsive NMC materials. The findings also highlight the promise of biogenic synthesis as a sustainable alternative to traditional methods and as a versatile platform for designing high-performing cathode materials for next-generation lithium-ion batteries.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 3","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the fabrication of an MXene/carbon nanotube (MXene/CNT) composite electrode via a one-step ultrasonication process, coupled with a redox-additive electrolyte to improve electrochemical performance,being is reported. The incorporation of sodium molybdate (Na2MoO4) into a sulfuric acid (H2SO4) electrolyte significantly enhances faradaic charge storage, extends the electrochemical window, and improves charge transfer kinetics. The resulting system exhibits a specific capacitance of 152 F g−1 at 3 A g−1, a substantial increase compared to 47 F g−1 at the same current density in H2SO4. Moreover, the energy density of the MXene/CNT composite electrode in the sodium molybdate redox additive reaches 41 Wh kg−1, nearly doubling that of the conventional H2SO4 electrolyte, with the power density being almost the same in both cases. This enhancement is attributed to the redox interactions between MoO42− ions and H+ ions, which facilitate efficient charge storage.
