Alloying silicon with secondary elements like boron has emerged as a promising strategy to improve the cycle life of silicon anodes, yet the underlying mechanism remains unclear. To address this knowledge gap, how boron concentration influences battery performance is systematically investigated. These results show a near‐monotonic increase in cycle lifetime with higher boron content, with boron‐rich electrodes significantly outperforming pure silicon. Additionally, silicon‐boron alloy anodes exhibit nearly three times longer calendar life than pure silicon. Through detailed mechanistic analysis, alternative contributing factors are systematically ruled out, and it is proposed that improved passivation arises from a strong permanent dipole at the nanoparticle surface. This dipole, formed by undercoordinated and highly Lewis acidic boron, creates a static, ion‐dense layer that stabilizes the electrochemical interface, reducing parasitic electrolyte decomposition and enhancing long‐term stability. These findings suggest that, within the SEI framework, the electric double layer is an important consideration in surface passivation. This insight provides an underexplored parameter space for optimizing silicon anodes in next‐generation lithium‐ion batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"13 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144304609","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}

However, due to their low Li+ diffusivity, DRXs need to be pulverized into nanoparticles to achieve high performance. Herein, a new strategy for overcoming this limitation is demonstrated, involving the design of as‐synthesized partially disordered oxides with a structure that lies between ordered layered and fully disordered, exhibiting a varying degree of local (dis)order. This unique structure activates new Li+ diffusion channels, improving percolation and transport properties. This strategy allows a large content of Li+ to be accessed in material with large, micron‐sized particles through highly reversible Cr3+/6+ and O redox, yielding a first discharge capacity of 286 mAh g−1 (881 Wh kg−1). The Li+ percolation network is further improved by substituting Ti with a mixture of multiple metals, which appears to locally decrease the migration barrier through lattice distortion. Proper tuning of the chemical composition, especially the content of metals with empty d orbitals, is established as a crucial factor for controlling the degree of disorder and mitigating voltage fade and hysteresis growth upon cycling.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"23 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144304610","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}

Currently, the safe use of Si-anode-based LIBs has been hindered by unstable electrolyte chemistry at a high temperature. The thermal decomposition of lithium hexafluorophosphate (LiPF6) and hydrolysis of the decomposition products can generate corrosive species (e.g., HF and POxFy) and exacerbate the surface parasitic reaction of Si, accelerating materials aging and posing challenges to stable Li storage. Here it is shown that the introduction of a functional electrolyte additive, 1,3-Divinyl-1,3-diphenyl-1,3-dimethyldisiloxane (DK244) effectively mitigates the issue. As a Lewis base, DK244 interacted with the Lewis acid PF5 from the thermal decomposition of LiPF6, so it helped to suppress the generation of the corrosive species and improve the high-temperature anode stability against electrolyte. The aging mechanisms of deeply lithiated SiOx/C (x ≈ 1) anodes during calendar storage at 60 °C are studied by using multiscale materials and electrochemical characterizations. The results revealed that DK244 assisted in mitigating the hydrolysis of the electrolyte while maintaining the chemically stable and mechanically robust of solid electrolyte interface so that it contributed to stable Li+ transport after high-temperature storage.

By facilitating data-driven insights, machine learning (ML) has become a potent instrument for addressing these issues. This perspective investigates how ML is used in the design and lifespan estimation of LIB cathode materials. The limitations of empirical approaches and cathode material deterioration mechanisms are highlighted. Subsequently, diverse ML techniques are explored, including regression models, deep learning, and optimization algorithms.

Nevertheless, zinc powder anodes encounter severe cycling instability at elevated depths of discharge (DOD) due to serious ion transfer barriers, parasitic side reactions, and stress‐induced mechanical instability, impeding their practical implementation. Here an electrochemical‐mechanical regulation strategy utilizing the viscoelastic synergy of branched oxygen‐rich oligomers and spherical elastic fillers, achieving significantly improved cycling performance, even under a remarkably high DOD by 96% is proposed. The oligomer's weak zinc coordination effect and expansive free volume facilitate rapid Zn2⁺ flux under high DOD, while its ether‐oxygen moieties immobilize water via hydrogen bonds, dynamically suppressing parasitic reactions. Concurrently, the spherical elastic fillers mitigate stress concentration through excellent anti‐shear stability, ensuring mechanical integrity and continuous electrical contact under significant volume strain. This synergistic electrochemical‐mechanical regulation enables unprecedented cyclability 430 h at 96% DOD, outperforming reported zinc anodes. Furthermore, Zn0.25V2O5‐matched full batteries achieve 95%–99.7% capacity retention over 200 cycles at rather low N/P ratios (2.51–4.89), highlighting their potential for high‐energy, cost‐effective energy storage.

However, O3-type Na-ion layered oxides experience severe structural distortions and phase transitions during electrochemical cycling, which significantly deteriorate battery performance. In this study, an ultra-stable O3-type high-entropy doping cathode material is developed, NaNi0.3Mn0.5Fe0.05Li0.05Ti0.05Cu0.05O2 (NMFLTC), for high-performance Na-ion battery. By partially substituted Ni of NaNi0.5Mn0.5O2 (NM) with Fe, Li, Ti, and Cu, Na+ diffusion and maintained the structural integrity of NMFLTC is successfully enhanced through the in situ formation of a high-entropy rock salt phase on the surface of the cathode material. This modification not only protects the cathode from structural degradation but also effectively mitigates phase transitions during cycling, leading to favored sodiation/de-sodiation electrochemistry and enhanced structure stability. Attributed to its structural superiorities, the high-entropy doping layered oxide cathode maintains 85.9% and 73.7% capacity retention at 0.1 C and 0.3 C after 200 and 600 cycles, respectively, which marks a significant improvement over traditional undoped NM cathodes.

Axially ligands can modulate properties comprehensively, e.g., inducing metal-to-semiconductor transitions and enhancing mobility. Compressive strains gestate 8 Dirac materials featuring three different cone types. Biaxial strain yields diverse semiconductors spanning wide bandgap spectra (0−1.59 eV at HSE06) and conforming to the newly proposed “unimodal model”.
