Inspired by the amusing drawing in van Gool's proceedings of the legendary first Belgirate conference on fast ion transport in solids in 1972, the picture shows how although the Na ions can easily migrate from one NaSICON crystal to the next, they cannot get any further at the boundaries to the glass and can only move with difficulty in the glass phase. Only along the tubular cavities can Na ions and protons easily slip through the glass areas and thus keep the overall conductivity high. More information can be found in the Research Article by F.

Here, the influence of three fluorinated additives, 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE), 1,2- bis(2,2,2-trifluoroethoxy) ethane (BTFE), and PhF, on the structure and dynamics of an MSE composed of [Li, Na, K, Ca]FSI, is investigated using molecular dynamics simulations—with the end-goal of improved calcium battery (CaB) electrolytes. The differences in additive chemical structure affect cation coordination, ionic cage persistence, and ligand exchange kinetics; while TTE and BTFE directly participate in cation coordination, PhF acts as a non-coordinating diluent, weakening the ionic network through spatial disruption. These additive-specific effects result in cation-dependent trends in coordination and mobility. Overall, the findings provide a proof-of-concept for rational additive selection in MSEs, shifting the design paradigm from optimizing bulk conductivity toward engineering coordination and interfacial behavior for CaB electrolytes.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 7","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202500239","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635605","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}

Nevertheless, their chemical reactivity, volumetric changes, and dendritic deposition profoundly influence their performance. Introducing an artificial solid-electrolyte interphase (ASEI) is one of the most effective ways to tackle this interfacial instability. However, due to unparalleled reactivity, the direct interfacial engineering of lithium is challenging. Herein, the modification of the polypropylene (PP) separator with lithiophilic zinc oxide (ZnO) and graphitic carbon nitride (gCN) is reported as an indirect yet effective strategy to tackle the interfacial instability of lithium. This work substantiates that ZnO.gCN PP modulates the electrolyte uptake, ionic conductivity, and Li+ transportation and reacts with the lithium metal to form an ASEI having rigid inorganic materials, leading to much lower nucleation overpotential, reduced polarization, and remarkable cycling stability of more than 500 cycles at 1 mA cm−2. The GITT studies further manifested the improved mass and charge-transfer kinetics of Li+ in the presence of ZnO.gCN PP. The postcycling high-resolution scanning electron microscopy and X-ray photoelectron spectroscopy analysis confirmed that the enhanced electrochemical performance resulted from uniform Li plating/stripping and suppressed electrolyte degradation. Furthermore, the practicality of ZnO.gCN PP is demonstrated through the significantly improved electrochemical performance of NCM811.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 7","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635008","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}

The bulk conductivity varies between 1.4 and 6.6 mS cm−1. The total conductivity showdecreasing values with increasing Zr deficiency due to the impact of the increasing fraction of glass phase. The calculated grain boundary conductivity is about two orders of magnitude lower than the total conductivity but does not correspond to the conductivity of any known glass composition of sodium silicates/phosphates. Nuclear magnetic resonance reveals three 23Na relaxation rates, the fastest of which is attributed to the NaSICON phase and the two slower relaxation rates to sodium orthophosphates and the glass phase. Thermal conductivity varies between 0.9 and 1.0 W m−1 K−1 at 25 °C. At elevated temperatures, a clear trend is observed toward lower thermal conductivity with a higher glass fraction. In addition, atom probe tomography is applied to precisely quantify the composition of specific microstructural regions found within the glassy phase. A scanning electron microscopy study of the surfaces of sintered pellets shows an increasing amount of glass phase between the NaSICON particles with increasing Zr deficiency. Furthermore, a time-dependent phase separation is observed in relation to the dynamic formation and dissolution of Na3PO4 domains.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 6","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202500093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339085","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}

To achieve high energy and power densities, the thickness of composite electrodes must be increased. The microstructure and mechanical properties of the composites must be carefully controlled to ensure sufficient contact between particles. The 400 μm-thick LiCoO2-Li10.35Ge1.35P1.65S12 (LCO–LGPS) composites are fabricated using LGPS with various particle sizes. The composites using small-sized LGPS particles exhibited higher capacity and retention than those using large-sized particles. In situ cross-sectional scanning electron microscopy with energy-dispersive X-ray spectroscopy reveals that the cracks generated during charging demonstrated self-closing during discharge in the composite with small-sized LGPS regardless of the generated locations, leading to high-capacity retention. However, this self-closing is not observed in the composite using large-sized LGPS. The self-closing behavior depends on the microstructure and mechanical properties of ASSBs. Furthermore, this self-closing finding provides new strategies for designing the microstructure and mechanical properties of ASSBs.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 6","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202500119","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339185","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}
