This process results in Ba evaporation, which complicates the control of the electrolyte surface composition. To address this problem, we herein examined the effect of modifying the electrolyte (Ba0.97Zr0.8Yb0.2O3−δ, BZYb20d) surface in anode-supported PCFCs by BaCO3 slurry coating followed by firing at 1300 °C. X-ray diffractometry (θ–2θ measurements) indicated a decrease in the amount of Yb2O3 precipitated on the surface of the thus treated BZYb20d, and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy revealed a decrease in the segregation of Yb2O3 at the treated electrolyte surface. Thin-film X-ray diffractometry (ω–2θ measurement) revealed a change in the lattice constant of the BZYb20d electrolyte (thickness = 10 μm) in a BZYb20d/NiO-BZYb20d half-cell as a function of the X-ray penetration depth from the surface to the bulk (i.e., near the BZYb20d/NiO-BZYb20d interface) at 25–900 °C in air, dry N2, and wet N2. At 900 °C, the lattice constant of BZYb20d after the BaCO3 treatment hardly changed upon going from the surface to the bulk, which suggested that the Ba content at the BZYb20d electrolyte surface was almost the same as that in the bulk. The thermal expansion coefficients and chemical expansion rates of the BZYb20d film electrolyte bulk were lower (∼0.66 and ∼ 0.33 times, respectively) than those of BaZr0.8Y0.2O2.9 and BaZr0.8Yb0.2O3−δ bulk. The BaCO3 treatment increased the maximum power density of the corresponding PCFC from ∼0.5 to ∼0.6 W cm−2. The cathode fabricated using the modified BZYb20d electrolyte showed a lower polarization resistance (0.07 Ω cm2) than that based on the unmodified electrolyte (0.22 Ω cm2). The Ba deficiency of the BZYb20d electrolyte surface that developed during high-temperature sintering was alleviated by the BaCO3 coating, and the interfacial resistance between the air electrode and electrolyte therefore decreased.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"431 ","pages":"Article 117030"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145217519","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}

Here, we present a rapid, one-hour mechanochemical synthesis of chloride electrolytes Li2BxCl4 (B = Zn, Mg, Zr and x = 1 and 2/3) via high-energy ball milling (HEBM), achieving the targeted spinel phase without the need for any annealing steps. In Li2ZnCl4 electrochemical impedance spectroscopy reveals an unexpected, reversible low-temperature ionic transition at ∼75 °C, leading to a dramatic increase in total Li+ conductivity, from 2.95·10−9 S·cm−1 at 25 °C to an extrapolated room temperature conductivity of 3.24·10−5 S·cm−1 following heating to 125 °C. To elucidate the structural origins of this transition, we employ neutron powder diffraction (NPD), variable-temperature powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), and 6Li MAS NMR spectroscopy. We explore the stabilization of the high conducting phase via the introduction of host cation vacancies and therefore increasing the Li/B ratio based on the spinel-related compounds, Li2Zn1/3Zr1/3Cl4 and Li2Mg1/3Zr1/3Cl4, synthesized via the same one-hour mechanochemical approach. Rietveld refinement of NPD data reveals a monoclinic lattice distortion and cation disorder in both compounds, which open new Li conduction pathways. In both materials, 2–4 orders of magnitude increase of conductivity is achieved by aliovalent Zr4+-substitution compared to the undoped counterparts Li2ZnCl4 and Li2MgCl4, leading to maximum bulk conductivities up to 10−4 S·cm−1 at room temperature. Notably, the investigated chloride-based solid electrolytes consist of non-critical elements and exhibit high thermal stability up to at least 190 °C which can be key for easy scalable processing. These results highlight the potential of spinel-based chloride electrolytes as candidates for next-generation solid-state battery applications, combining rapid and scalable synthesis with promising ionic transport properties.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"428 ","pages":"Article 116952"},"PeriodicalIF":3.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144572787","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}

In this study, a new lithium nickel manganese oxide precursor, a nickel‑manganese composite oxide, was prepared using a liquid-phase oxidation method, and the cathode material was synthesized through high-temperature calcination. The effects of different raw material ratios on the preparation of LiNi0.5Mn1.5O4 and their mechanisms were investigated. Considering that acetylene black tends to undergo thermal decomposition and electrochemical reactions in high voltage systems, leading to degradation and performance decline, Super C65 was used as a conductive agent instead of acetylene black to achieve better electrochemical performance. The experimental results indicate that when the Ni/Mn molar ratio is 1:2.5, the resulting nickel‑manganese composite oxide exhibits good crystallinity and a Fd-3 m space group structure with uniform particle dispersion and weak agglomeration. When mixed with LiOH and subjected to high-temperature calcination, with a Li/M molar ratio (M = Mn + Ni) of 0.51, the formation of the LixNi1-xO impurity phase and the polarization of the material were significantly improved. The prepared LiNi0.5Mn1.5O4 has uniform particle size, well-defined octahedral morphology, and pure phase characteristics. At a current density of 0.2C, the initial discharge specific capacity reaches 135 mAh/g and remains at 118 mAh/g after 200 cycles. After replacing acetylene black with Super C65, the initial discharge specific capacity of LiNi0.5Mn1.5O4 at 0.2C increased to 140 mAh/g, with a discharge specific capacity of 122 mAh/g after 200 cycles, and the electrochemical impedance decreased from 304 Ω to 266 Ω. This improvement is attributed to the smaller particle size of Super C65, which can embed between the spinel material particles to form a good conductive network, increase the lattice parameters of the disordered space cluster structure, provide more diffusion paths for ions, facilitate the rapid change of element valence states, and thereby demonstrate higher electronic conductivity. Although the cycling retention slightly decreased, the overall electrochemical performance was enhanced.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"428 ","pages":"Article 116914"},"PeriodicalIF":3.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144239939","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}
