A common approach to tailor the electrolyte’s properties is the use of cosolvents and additives. While their role in lithium- and sodium-based systems is progressively elucidated and even become established as standard cell components, the impact in KIBs still demands for a fundamental investigation. In this study, a comparative analysis of K-ion full cells based on a potassium vanadium phosphate cathode (KVP/C) and a graphite anode employing several electrolyte formulations was carried out to shed light on the complex interrelations of cyclability and the use of prevalent electrolyte additives.

Therefore, an electrically conducting matrix that hosts elemental sulfur and prevents polysulfide dissolution into the electrolyte is highly desirable. Covalent ceramics prepared through a polymer pyrolysis route contain polar bonds and a 3D network of conducting carbon phase that could enable chemical and physical adsorption of soluble lithium polysulfides (LiPSs) and electrical transport, respectively. Herein, we report the preparation of boron-integrated silicon carbonitride (Si–B–C–N) from thermochemical conversion of a single-source precursor and its use as a sulfur host for LSBs. The SiBCN host provided superior electrochemical performance compared to the neat SiCN host, delivering an initial capacity of 1039.3 mAh gs−1 and retaining 858.8 mAh gs−1 after 100 cycles at 0.1 C with nearly 100% coulombic efficiency, exhibiting a 25.8% improvement over SiCN, possibly associated with the presence of B─N bonds, which enhanced the adsorption of intermediate LiPSs. These findings highlight the advantages of compositional tuning in PDCs, which can enhance the reversibility of sulfur's electrochemical reactions, inhibit active material loss, and improve cycling stability in LSBs.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148462865","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}

A metallic 1T-MoS2-enabled improved capacity and kinetic strategy is presented for a mesoporous core–shell CuO@TiO2 anode, where the content of 1T-MoS2 is systematically optimized to regulate interfacial charge transport and ion-diffusion behavior. The optimized CuO@TiO2/1T-MoS2 (10 wt%) composite integrates a nanosized CuO core, a TiO2 shell that buffers volume expansion, and metallic 1T-MoS2 nanosheets that form a highly conductive and defect-rich network. As a result, the optimized electrode delivers a high reversible capacity of ∼1017 mAh g−1 with 84.8% capacity retention after 200 cycles at 200 mA g−1 in LIBs. In sodium-ion batteries, it maintains a stable capacity of ∼223 mAh g−1 after 200 cycles. Kinetic analyses confirm reduced charge–transfer resistance and a balanced contribution of surface-controlled capacitive and diffusion-controlled storage.

Although separator functionalization with catalytic materials has been widely explored, the fundamental role of crystallinity in governing polysulfide conversion remains insufficiently understood. Herein, the effect of crystallinity on polysulfides regulation is systematically investigated using Co3S4 as a model system. Amorphous Co3S4 (A-Co3S4) and crystalline Co3S4 (C-Co3S4) are deliberately constructed to establish a direct structure–property correlation. Compared with its crystalline counterpart, A-Co3S4 features a disordered atomic configuration with abundant coordination-unsaturated sites and defect-induced electronic states, enabling stronger polysulfides adsorption and accelerated catalytic conversion. When integrated onto a polypropylene separator, the A-Co3S4-based interfacial layer effectively suppresses polysulfide migration, enhances interfacial charge transfer, and promotes ion transport kinetics. As a result, the A-Co3S4@PP-based cell delivers an initial capacity of 748 mAh g−1 at 1 C and maintains 537 mAh g−1 after 1000 cycles, corresponding to a low capacity decay rate of 0.02% per cycle.

However, their practical application is severely hindered by drastic volume changes during repeated lithiation and delithiation, which lead to unstable interfacial chemistry and rapid capacity fading. Electrolyte design has therefore emerged as a critical strategy for regulating interfacial reactions and enabling the stable operation of silicon-based anodes. This review systematically summarizes recent advances in electrolyte engineering for silicon-based anodes, with particular emphasis on the rational design of electrolyte components and formulation strategies. From the perspective of electrolyte composition, progress in lithium salts, solvents, and functional additives is critically discussed, highlighting the evolution from conventional single-component systems to multifunctional and synergistic electrolyte formulations. From the standpoint of formulation strategies, the evolution from empirical optimization to mechanism-driven approaches is focused, including molecular structure regulation, solvation structure regulation, AI-assisted electrolyte discovery, and solid-state electrolytes. Finally, electrolyte development for silicon-based anodes is analyzed, and unified design principles are proposed to guide future studies.

Accurate characterization of these changes is essential for a deeper understanding of cycling stability, particularly under different charging/discharging rates. Herein, in situ X-ray diffraction (XRD) and digital image correlation (DIC) were combined to investigate the chemical strain of graphite anodes at different current densities. In situ XRD results reveal the phase-transition-induced volume changes of active graphite particles, allowing the determination of the partial molar volume of lithium ions in active material. These results were further incorporated into the overall strain analysis of composite graphite anode measured by DIC, enabling the quantification of the strain contributions from inactive components, as well as the corresponding partial molar volume of lithium ions. The results show that the overall strain decreases as the current density increases from 0.1 to 0.2 C. The residual strain contribution from inactive materials is significantly greater than that from active materials at both current densities, and the strain associated with inactive components is much higher at 0.1 C than at 0.2 C.

A dataset of 4156 sodium-based battery compounds was constructed from the Materials Project Battery Explorer and represented using 107 structural, chemical, and electronic descriptors. To address incomplete descriptor availability in large chemical spaces, a two-step learning strategy was employed, where a random forest model was first used to predict missing features prior to property estimation. Multiple machine learning models were benchmarked, with light gradient boosting machine (LGBM) exhibiting the highest predictive accuracy and further optimized using the sparrow search algorithm (SSA) to form an SSA-LGBM hybrid model. The optimized framework was subsequently applied to screen 12,823 sodium-containing compounds for average voltage and specific capacity. Initial screening identified 70 candidate materials based on practical performance thresholds, which were further refined using criteria, including thermodynamic stability, electronic conductivity, elemental abundance, cost, and environmental considerations. Ultimately, 15 promising cathode candidates were identified and validated through formation energy and bandgap analysis, as well as comparison with established sodium-ion battery cathodes. This study demonstrates a scalable and interpretable strategy for accelerating cathode discovery in sodium-ion battery systems.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386627","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}

This study investigates the role of electrolyte composition in governing SEI evolution, lithium consumption, and aging behaviors in LiCoO2|SiOx cells using complementary experimental and modeling approaches. Electrolytes containing fluoroethylene carbonate (FEC) exhibit significantly improved cycle retention compared with conventional ethylene carbonate (EC)-based electrolytes. Nuclear magnetic resonance spectroscopy reveals two distinct SEI formation pathways: EC decomposition yields an organic-rich SEI, whereas FEC and PF6− decomposition produce an inorganic, LiF-rich SEI. The total SEI mass remains nearly constant after aging, indicating dynamic breathing behavior rather than continuous growth. Based on these insights, we developed a pseudo-two-dimensional model that couples electrolyte consumption and SEI growth by distinguishing organic and inorganic SEI components with different mechanical responses to SiOx volume changes. The model successfully predicts electrolyte-dependent aging, reproducing the influence of FEC concentration on overpotential, loss of lithium inventory, and capacity fade. The rate performance of the cell is primarily limited by lithium transport within SiOx particles and by electrolyte transport across the electrode, particularly under fast-charging conditions. Our combined experimental-modeling approach provides a foundation for electrolyte-specific aging assessment and electrolyte design for SiOx-based batteries.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70391","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386119","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}
