This study focuses on the first step of the process, studying the effect of shear milling on the structural, morphological, and electrochemical properties of NMC622 cathode materials: pristine NMC powders, dried slurries, and electrode manufacturing scraps. Depending on the energy supplied to the system, shear milling could induce partial fragmentation of NMC secondary particles and slight alterations of the crystalline structure, increasing the microstrain rate. Electrochemical tests highlight the detrimental effect of these alterations on electrochemical performance, with a decrease in specific capacity and rate capability. Investigations on electrode manufacturing scraps also demonstrate that in this case, the aluminum current collector acts as a protective component during milling and significantly limits the fragmentation of NMC secondary particles as well as the crystalline structure alteration, compared to isolated NMC material at equivalent milling energy. This work demonstrates that the first step of the direct recycling process, shear milling, is already critical and must be carefully controlled to preserve the structure of the NMC and its electrochemical performance.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70413","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616314","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}

The critical drawbacks of quinone unit–containing electrodes are poor electronic conductivity and dissolution during electrochemical cycling, which poses a limitation in their practical deployment. Herein, we report a rational strategy of constructing organic–inorganic hybrid cathode that synergistically overcomes the intrinsic drawbacks including dissolution, limited conductivity, and sluggish electrochemical kinetics. In situ grown C─S─C enriched copolymer of quinone unit and thiophene (Pbz-Th) on nitrogen-doped siliconoxycarbide (g-(C/N)SiO) is explored as a cathode material in AZIB. Mechanistic investigations led by spectroscopic analysis reveal that oxygen and sulfur moieties in the copolymer participate in Zn2+ coordination, enabling reversible Zn2+ storage and enhanced reaction kinetics, whereas g-(C/N)SiO exhibits a fast and reversible pseudocapacitive charge-storage process. Notably, the C─S units within the copolymer and the auxiliary active sites of g-(C/N)SiO contribute to reversible surface redox processes, leading to enhanced capacitance and improved cycling stability. The resulting Pbz-Th@g-(C/N)SiO cell delivers a maximum discharge capacity of 181 mAhg−1 at 0.05 Ag−1 with 97% Coulombic efficiency and capacity retention of 90% over 500 cycles at 1 Ag−1. Integrating redox-active organic motifs with a conductive g-(C/N)SiO scaffold addresses dissolution, enhances electronic transport, and improves interfacial kinetics.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615924","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}

However, their practical application is still limited by insufficient intrinsic activity. Herein, we successfully prepared cobalt (Co) and molybdenum (Mo) co-embedded nitrogen-doped porous carbon nanofibers (a-Co/Mo@NCNFs) as efficient bifunctional electrocatalysts via electrospinning followed by high-temperature pyrolysis. The introduction of Mo as an electronic modulator can tailor the electronic structure of Co sites, thereby optimizing the adsorption/desorption behavior of oxygen-containing intermediates. Meanwhile, the hierarchical porous architecture facilitates rapid mass/electron transport and maximizes the exposure of catalytic sites. The optimized a-Co/Mo@NCNFs catalyst exhibits outstanding bifunctional electrocatalytic activity, delivering a half-wave potential of 0.831 V for oxygen reduction reaction and a low overpotential of 371 mV at 10 mA cm−2 for oxygen evolution reaction. Notably, Zn-air battery based on the catalyst achieved higher open circuit voltage and power density than the benchmark Pt/C+RuO2 system, demonstrating its great potential as an efficient and durable alternative for energy conversion and storage applications.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615927","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 study, we proposed a scalable approach to produce nonwoven nanofiber web-based polyimide (PI) separators, combining syringeless electrospinning with roll-pressing treatment. This process yields large-area poly(amic acid), followed by imidizaition, nanofiber membranes without pore damage, exhibiting excellent mechanical strength (∼22.2 MPa), and thermal stability up to 530 °C without structural deformation. The fabricated PI separator shows high ionic conductivity (3.5 mS cm−1) and lithium ion transference number of 0.68. Electrochemical evaluation shows that the NCM622//graphite full cell exhibits 168.9 mAh g−1 discharge capacity with 86.5% Coulombic efficiency at 0.1 C and retains 143.83 mAh g−1 after 200 cycles at 1 C, demonstrating superior long-term cycling stability at high rate. Additionally, the PI-based cell retains 91.02% of its capacity after 30 cycles at 45 °C under 0.5 C conditions. These results demonstrate that large-scale, high-efficiency processing enables practical production of high-performance PI separators.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70415","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615826","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}

While Zn movement has been qualitatively described in Zn–air batteries, it has not been quantitatively characterized or incorporated into computational models. We present quantitative measurements of Zn particle movement in a discharging cylindrical AA Zn–MnO2 battery using pseudo-operando X-ray micro-computed tomography and individual particle tracking. Using a custom alignment and machine learning-enabled segmentation workflow, we track individual Zn particles from 0% to 52% depth of discharge (DOD) under a pulsed protocol. Zn particles move inward toward the current collector at an average rate of −5.1×10−4/%DOD driven by the spatial gradient of ZnO precipitation. This discharge behavior is reproduced by a computational model in which convective Zn transport is described as granular flow via the Navier–Stokes equation. The modeled movement rate of −5.7×10−4/%DOD is within 12% of the experimental value. Because the spatial distribution of Zn determines whether material remains active in the electrode, accurate prediction of Zn movement has direct consequences for estimating usable Zn–MnO2 battery capacity relevant to real-world use.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70401","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148553383","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}

Here, we investigated the impact of different monovalent insertion ions on the performance and reliability of the same electrode. We chose Berlin Green (BG, FeIII[FeIII(CN)6]), a Prussian Blue analog (PBA), due to its rigid structure, ability to accommodate different ion sizes, and two different redox-active Fe atoms. We conducted electrochemical tests, intermittent scanning electron microscopy (SEM), and operando substrate curvature experiments on BG as we changed the counter electrode and electrolyte. With this novel experimental strategy, we report for the first time sequential insertion/extraction of all three ions in/from the same single BG electrode, eliminating electrode variations and ensuring direct comparability of ion insertion, degradation, and stress. While Li+ and Na+ follow comparable pathways, K+ leads to distinct electrochemical and mechanical responses, underscoring ion-specific interactions within the host framework. We demonstrate that BG enables highly reversible insertion/extraction with a high tolerance to ionic size variation and great surface stability, despite volume changes and phase transitions. These results position BG as a model system for understanding alkali ion insertion and as a versatile and sustainable electrode material for future energy storage systems.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70368","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148553461","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}
