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.

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}

Commercial cylindrical cells of type 21,700 are subjected to calendar aging and cyclic aging with different parameters in a long-term study. The impact of the aging parameters on the four different cathode materials assessed (lithium–nickel–manganese cobalt oxide (NMC), lithium–nickel–cobalt–aluminum oxide high energy (NCA-HE), lithium–nickel–cobalt–aluminum oxide high power, and lithium–iron phosphate oxide (LFP)) is examined with a portfolio of diagnostic methods: capacity test, Ohmic resistance test and the core of this study, impedance analysis, together with sophisticated equivalent circuit modeling (ECM). It was found that the NMC cell degraded fastest under all aging conditions, the most durable was in most cases the NCA-HE cell. Only for one cyclic aging procedure, the LFP cells performs the best. The diagnostics shows that quantitative analysis of Nyquist plots is not sufficient for aging tracking and that some aging effects can only be detected by pulse discharging test. Moreover, capacity and mean Ohmic resistance deduced from electrochemical impedance spectroscopy test allow extrapolation to forecast further aging under diverse aging conditions.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 5","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400713","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100479","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, Li-rich cathode materials suffer from structural instability, voltage degradation, and capacity fading upon cycling. Al-doping can improve electrochemical performance by stabilizing the structure and suppressing the phase transitions for Li-rich cathodes. In this paper, we investigate the effect of different amounts of Al with the general formula Li1.2Mn0.54-xNi0.13Co0.13AlxO2 and Li1.2-xMn0.54Ni0.13Co0.13AlxO2 (x=0.02, 0.05, 0.1) cathode materials. The Li and Mn elements were replaced by Al, and the electrochemical performance was compared to pristine Li1.2Mn0.54Ni0.13Co0.13O2. The Li and Mn elements were replaced by Al, and the electrochemical performance was compared. The impact of substitution of Mn and Li by Al on the structural and morphological properties has been investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The charge and discharge tests show that doping with Al substitution leads to improved electrochemical performance, enhancing both the cycling stability and rate capability of the Li-rich cathode materials. Along with the improved specific capacities, these materials demonstrate superior rate performance, particularly for the composition with the lowest Al content.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 5","pages":""},"PeriodicalIF":5.1,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400652","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100564","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}
