A systematic comparison between low-energy ball milling (LBM) and high-energy ball milling (HBM) reveals that tribochemical processing intensity determines composite microstructure and electrochemical performance. HBM-processed composites exhibit superior homogenization confirmed by quantitative FIB-SEM analysis, achieving discharge capacities of 1110 mAh g_S⁻¹ at 0.05 C and 669 mAh g_S⁻¹ at 0.5 C. Despite lower bulk electronic conductivity, HBM composites demonstrate enhanced performance consistent with shortened solid-state diffusion lengths and increased triple-phase boundary density. SOC-dependent electrochemical impedance spectroscopy reveals that HBM composites accumulate only 19% impedance growth at 100% SOC over 34 cycles compared to 41% for LBM counterparts, indicating superior interfacial stability. Time-of-flight secondary ion mass spectrometry provides spatial evidence for heterogeneous lithiation, with codetected TiS⁺ and Li₃S⁺ species consistent with gradual structural reorganization along the conversion trajectory. Scalability is demonstrated through dry-film electrode fabrication, and HBM-processed cathodes achieve initial capacities of 1240 mAh g_S⁻¹ and retain 950 mAh g_S⁻¹ after 80 cycles.

When current-collector or interlayer properties remain expressed, reversibility is governed by multiple interfacial bottlenecks that extend beyond nucleation to lateral growth, contact retention, interfacial reactivity, and stripping. Here, we reposition nucleation overpotential as one descriptor within a broader substrate-centered framework for deposition-interface design. We focus primarily on low- or negligible-pressure conditions and electrolyte/interphase regimes in which substrate effects remain clearly expressed and discuss additional substrate-controlled factors, including surface migration, adhesion/contact retention, alloying or interfacial reactivity, crystallographic texture/facet exposure, and mesoscale heterogeneity. We further outline a descriptor-guided workflow that links dominant failure signatures to the most likely controlling bottlenecks, the most informative measurements, and corresponding interface-design strategies. Because the controlling factor depends on chemistry, architecture, and failure mode, we propose moving from one-metric ranking toward a more diagnostic, descriptor-guided design logic for anode-free metal batteries.</p>","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 9","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148849234","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}

Boron nitride (BN), with its diverse crystal structures and excellent performance, has been widely used in electrolytes for SSLMBs. Herein, we provide a comprehensive review of research progress on BN-based materials applied in solid-state electrolytes (SSEs) for SSLMBs. First, the relationships of the basic structure, properties, and synthesis of BN are briefly elucidated. Subsequently, the application strategies and mechanisms of raw/modified BN in polymer-based and inorganic solid electrolytes are systematically elaborated and discussed, emphasizing its role in enhancing mechanical strength, inhibiting lithium dendrites’ growth, optimizing ion transport, and stabilizing the interfaces. Representative research results demonstrate that SSEs incorporated with BN-based materials can significantly enhance the cycling stability, ionic conductivity, and rate performance of SSLMBs.

Lithium symmetric coin cell (Li||Li) is widely used to study Li depositing/stripping, and metrics such as voltage polarization and cycle life are interpreted as intrinsic properties of Li metal anodes. However, under the prevalent cell architectures, we found that besides the Li foil, the stainless steel (SS) component inside the cell also undergoes parasitic Li plating/stripping during cycling. This parasitic process (i) significantly enlarges the reaction area and dilutes the true current density, thereby confounding the above metrics and (ii) exhibits poorer reversibility on SS. By different current density, areal capacity, and Li foil thickness, the directional bias of symmetric coin cell lifetime assessment caused by parasitic depositing/stripping is revealed: high depth-of-cycling leads to an apparent underestimation of cycle life, whereas shallow cycling can overestimate it. The similar artifacts are also observed in full cells, indicating the broad relevance of the parasitic lithium deposition puzzle. Therefore, we advocate that future studies explicitly control and report current density, areal capacity, and Li excess, and employ advanced cell-design remedies to suppress SS-mediated Li deposition.

Although many studies have investigated PC charging for LIBs, this work represents, to the best of our knowledge, the first instance in which PC charging is applied to sodium-ion batteries (SIBs). Using a transparent measurement and evaluation protocol, we show that PC charging provides no apparent fast-charging benefit for commercial Na₄Fe₃(PO₄)₂(P₂O₇) and hard carbon 40 20 35 pouch cells with 150 mAh nominal capacity. Compared to conventional constant current charging, PC charging results in an increased overpotential because higher current amplitudes are required to compensate for charging interruptions. In addition, PC charging does not effectively shorten the duration of a subsequent constant voltage step. We further discuss that PC protocols with high pulse frequencies (&gt;100 Hz), often reported in scientific literature, may not be reliably generated due to instrumental limitations. Moreover, we illustrate that PC charging data must be interpreted carefully to avoid misleading conclusions about alleged fast-charging benefits.
