However, its practical application is severely hindered by low Coulombic efficiency, large volume fluctuations, and safety hazards arising from uncontrollable dendrite growth. Herein, we design a three-dimensional composite Li metal anode via a scalable route: carbon nanotubes with acetylene black to form spherical hosts, followed by molten Li infusion in the presence of aluminum nitride (AlN) particles. Benefiting from the in situ reaction between Li and AlN, a hybrid network of highly Li+-conductive Li3N and lithiophilic LiAl alloy is uniformly generated within the carbon framework, creating a mixed electron/ion conduction pathway. This 3D architecture provides enhanced interfacial area, homogenizes Li+ flux, buffers volume expansion, and effectively suppresses dendritic Li deposition. Consequently, symmetric cells achieve ultrastable cycling for over 2400 h at 1 mA cm−2. When paired with a LiFePO4 cathode, full cells deliver 158 mAh g−1 and retain 82.2% capacity after 500 cycles at 1 C.

The realization of practical SSSMBs relies on the development of advanced inorganic solid electrolytes (ISEs). Among the ISEs investigated, NASICON-type Na1+xZr2SixP3−xO12 (0 ≤ x ≤ 3, NZSP) solid electrolytes have attracted significant attention for their excellent chemical stability, environmental robustness, and wide electrochemical stability window. However, their practical implementation remains constrained by insufficient room-temperature Na+ conductivity, stemming from sluggish bulk transport and high grain-boundary impedance, and by an unstable Na/NZSP interface that elevates interfacial resistance and promotes dendrite-induced failure during cycling. This review examines the structural and electrochemical features of NZSP solid electrolytes and critically analyzes the key factors governing Na+ transport across the bulk crystal lattice, grain boundaries, and interfacial regions. Building on this foundation, it surveys recent advances in doping, grain-boundary engineering, and interfacial modification aimed at enhancing the ionic conductivity of NZSP solid electrolytes and stabilizing the Na/NZSP interface. Overall, NZSP modification strategies are inherently multifunctional, and integrated designs concurrently addressing bulk transport, grain-boundary conduction, and interfacial stability offer a particularly promising route toward practical, dendrite-free SSSMBs.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 11","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177537","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}

Here, we separately investigated the anionic PO43− and cationic Ti4+ modification for the LMFP cathode. The results show that Ti modification improves the bulk structure and interfacial stability, while also reducing the particle size. This is beneficial for alleviating stress release of the LMFP under high voltage and inhibiting interfacial transition metal dissolution, thus significantly improving the electrochemical performance. The Ti-modified sample of Ti-LMFP@C exhibits an initial capacity of 125.88 mAh g−1 in 18650 full cell at 1C rate, with a capacity retention of 96.98% even after 300 cycles, which is much higher than the bare sample and PO43−-modified sample. In addition, the Ti-LMFP@C battery presents a lower DCR under different states of charge (SOC). The cycled battery disassembly analysis confirms that the transition metal dissolution can be effectively suppressed and the anode structure stability can be improved through the Ti modification.

Replacing liquid electrolytes with solid ion conductors fundamentally changes electrode operation from liquid-mediated wetting to contact-dependent solid-state transport. Consequently, polymer binders are no longer passive adhesives but multifunctional interphases that maintain solid–solid contact, regulate stress evolution, stabilize interfaces, and preserve ion/electron transport pathways. This review summarizes recent advances in binder engineering for sulfide-based ASSBs from the perspectives of mechanical resilience, chemical compatibility, and transport regulation. We first discuss the key failure mechanisms governing binder design, including contact loss, stress accumulation, interfacial degradation, solvent incompatibility, and transport obstruction. Representative strategies are then reviewed, including elastic and stress-dissipating binders, dynamic and mechanically adaptive networks, polarity-regulated and solvent-compatible architectures, postactivated adhesive binders, and ion-conductive binders. Finally, we propose a multidimensional evaluation framework based on cycling durability, cell operating-voltage range, cathode chemistry, and testing conditions. By redefining binders as multifunctional mechano-chemical-transport regulators, this review provides design principles for linking molecular binder engineering with practical sulfide-based ASSB manufacturing and operation.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149146267","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, VO2(M)@Ti3C2 hybrid composites are employed in a symmetric energy storage system via hydrothermally induced self-assembled growth followed by annealing. The three-electrode configuration of the as-synthesized VO2(M)@Ti3C2 hybrid composites delivered a high specific capacity of 264.2 C g−1 at 1 A g−1.

Simultaneously, this electrode has shown 100% capacitive retention and Coulombic efficiency over 8000 cycles at 1 A g−1. The charge-storage mechanism is found to be diffusion/intercalation-dominated pseudo-capacitance, with no bulk phase change upon repetitive cycling.

They enable physical insights into the processes while building datasets to train AI surrogates for electrode microstructure and manufacturing optimization. Hence, the automation of parameter optimization for mesoscale simulations remains imperative. Optimization algorithms that do not require prior knowledge or experience simulating a specific chemistry/system are the ideal solution. One such optimizer is the particle swarm optimizer (PSO). However, in the classical serial implementation, the evaluation time varies across different parameter sets. This means the optimizer has to wait for all simulations to finish at each iteration, which can lead to unnecessary use of computational resources. This study presents an optimization framework that implements asynchronous PSO (APSO), enabling more efficient resource use to find the global optimum, i.e., parameter values that yield model outputs that agree with experiments. The effect of different APSO configurations on convergence was tested. The framework was then used to find the optimal parameters for two different mesoscale discrete element method simulations. The data acquired from the automated search were then analyzed to study the models’ behavior within the chosen parameter search space.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70490","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205432","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, most sodium-ion batteries use flammable liquid electrolytes. Replacing these with nonflammable solid-like electrolytes can improve safety, reduce leakage, and increase energy density. Ionogels, which immobilize ionic liquid electrolytes within a solid matrix, are particularly attractive because they combine the advantages of ionic liquids, including high thermal stability, ionic conductivity, safety, and electrochemical stability, with the benefits of solid electrolytes. Despite these advantages, optimizing electrode–electrolyte interfacial contact remains a key but understudied challenge. This work examines how liquid loading and salt concentration affect the mechanical properties and interfacial contact of silica-based ionogels. Increasing both parameters reduces the Young’s modulus to as low as 22 MPa while maintaining high ionic conductivity (4.3 mS cm−1). Higher salt concentrations improve compatibility with sodium metal and increase the critical current density to 0.5 mA cm−2.

Four salts, featuring acetate, nitrate, perchlorate, and imide anions, were selected to span a wide range of chaotropic and kosmotropic behaviors according to the Hofmeister classification. By combining 1H, 17O NMR, and infrared spectroscopy with viscosity measurements, a strong correlation emerges between the anion’s nature and its ability to weaken (chaotropicity) or reinforce (kosmotropicity) the water hydrogen-bond network. For the nitrate, at the boundary between chaotropic and kosmotropic behavior, and the weakly chaotropic perchlorate, results suggest a uniform solvation around [Mg(H2O)x]2+ clusters; NO3− may retain some interaction with water around Mg2+, while ClO4− appears more decoupled from Mg2+. In contrast, the strongly chaotropic TFSI− (bis(trifluoromethanesulfonyl)imide anion) induces a more pronounced perturbation of the hydrogen-bond network, with TFSI− largely outside the Mg2+ hydration shell. Finally, the anion-dependent solvation contributes to electrochemical performance. A 4 m magnesium perchlorate electrolyte exhibits markedly enhanced capacity retention and Coulombic efficiency than a 4 m magnesium acetate electrolyte. However, the overall electrochemical behavior cannot be described by a simple monotonic relationship with the Hofmeister classification.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.70499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149145921","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}
