However, the influence of synthesis route and resulting microstructure on transport behavior remains incompletely studied. We prepared Li2OHCl in 3 ways: a) cold-pressing of solid-state-synthesized orthorhombic and cubic Li2OHCl powders, b) sintering of these powders into pellets, and c) reactive sintering of high-energy ball-milled LiCl and LiOH reagents. We studied the impedance spectra for route a) at 25 °C, for route b) from ∼25–270 °C, and for route c) during the reactive sintering process to form the cubic phase, coupled to in-situ XRD. Cold-pressed powders typically exhibited a single impedance arc, while ex-situ sintered pellets exhibited an offset resistance with lower activation energy (∼0.44–0.48 eV) >60 °C and an arc with higher activation energy (∼0.6–1.2 eV). With increasing temperature, the offset feature increasingly dominated the impedance spectra, and its associated conductivity (1.9 × 10−3 Scm−1) was in good agreement with the total conductivity magnitude (1.3 × 10−3 Scm−1) and activation energy (0.42 eV) measured during reactive sintering of reagents once the cubic phase was obtained (>160 °C). Spectra were simulated using the brick layer model corresponding to the microstructure observed by SEM and varied specific conductivities and permittivities. Based on the above results, we attribute the offset feature to grains and the arc to blocking grain boundaries. A signature of possible proton transport in adsorbed H2O layers was observed in non-Arrhenius behavior below ∼60 °C, rendering separation of grain and grain boundary Li transport challenging at room temperature.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"431 ","pages":"Article 117038"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145262984","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 effect of deposition temperature on nuclei size, nucleation density, and growth of deposited Zn metal is studied by ex-situ microscopy investigations. Lowering the deposition temperature leads to smaller nuclei, higher nucleation density, and smoother zinc growth, forming a dendrite-free electrode surface. Compact and smooth zinc deposits contribute to long-term stability. There is no change in overpotential for the cell at −10 °C for more than 400 h. Long-term Zn deposition in Zn/Cu cells achieves an average coulombic efficiency (CE) of 99.2 % in the last 50 cycles using ZnCl₂·10H₂O electrolyte. The performance of electrolytes is evaluated in zinc-ion batteries with (zinc hexacyanoferrate) ZnHCF cathodes. The electrochemical studies show that the capacity of our zinc-ion battery in molten hydrated electrolytes increases from 17 mAh g−1 at −10 °C to 72 mAh g−1 at 40 °C, using n = 10 and n = 1.5 compositions of molten ZnCl₂ electrolyte.

However, their commercialization is limited by dendritic growth, interfacial instability, and safety risks associated with liquid electrolytes. In this work, composite solid polymer electrolytes (CSPEs) are developed by incorporating various (Al2O3, BaTiO3, and ZrO2) ceramic fillers into a PVDF-HFP/LiTFSI matrix via a scalable solution casting method. Among these, optimized 10 wt% ZrO2-based CSPE (PLZ) delivers the highest room-temperature ionic conductivity (9.26 × 10−5 S cm−1), excellent Li+ transference number (0.55), superior tensile strength (3.23 MPa), wide potential window (5.33 V), and good flame retardancy. Li/Li symmetric cells using PLZ showed stable lithium plating/stripping for more than 480 h at 0.10 mA.cm−2 with a low overpotential of ∼7 mV. Electrochemical impedance spectroscopy and equivalent circuit fitting confirmed the lowest increase in interfacial resistance after cycling. Time-resolved distribution of relaxation time (DRT) and 2D contour analysis revealed that PLZ maintained stable SEI and charge-transfer resistances, while bare CSPEs showed growing interfacial instability during cycling. These improvements are attributed to Lewis acid-base interactions and surface charge effects that reduce crystallinity and promote Li+ mobility. Full-cell evaluations with LiFePO4 and NMC111 cathodes demonstrated high discharge capacities and good cycling stability. Thus, this study offers a promising pathway for developing robust and safe CSPEs for next-generation solid-state LMBs.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"430 ","pages":"Article 117008"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913477","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}
