In the present work, in situ X-ray diffraction studies, simultaneous thermal analysis, and AC impedance spectroscopy, each performed under controlled value of steam partial pressure (pH2O), were carried out to elucidate the crystallographic features of the transformation and resolve the conductivity in the high temperature phase. The studies reveal that the material transforms to a cubic phase at a temperature of approximately 116 °C, that the activation energy for proton transport in the cubic phase is 0.304(2) eV, and the magnitude of the conductivity is comparable to that of Cs2(HSO4)(H2PO4). Despite differences in the room temperature structures of Cs2(HSeO4)(H2PO4), Cs2(HSO4)(H2PO4), and CsH2PO4, each has a monoclinic to cubic transformation entropy of approximately 23 J/mol(CsHxXO4)/K. Under pH2O = 0.05 atm, the cubic phase of Cs2(HSeO4)(H2PO4) is stable to approximately 250 °C. Under elevated pH2O (0.3 atm), exsolution of a trigonal phase, with structure analogous to that of Cs3H(SeO4)2, was found to accompany the transformation to the cubic phase. While the driver for this transformation is not fully known, the cell volumes of both the exsolved and matrix phases indicate they are chemically distinct, respectively, from Cs3H(SeO4)2 and Cs2(HSeO4)(H2PO4), suggesting additional chemical levers for control of transformation behavior.</div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"416 ","pages":"Article 116690"},"PeriodicalIF":3.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142148262","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}

To clarify the charge-discharge mechanism of Li2S−V2S3−LiI, we investigated microstructural changes during charge-discharge cycles via transmission electron microscopy (TEM). The microstructure of 90(0.75Li2S·0.25V2S3)·10LiI before charge-discharge measurement was characterized by LiVS2 and Li2S−LiI nanocrystallites in an amorphous matrix. In the Li2S−LiI domain, the Li2S−LiI nanocrystallites with an antifluorite-type crystal structure amorphized after charging and reprecipitate as Li2S−LiI nanocrystallites after discharging.

An additional challenge in conventional water electrolyzers is the lack of separation of the generated gases, hydrogen and oxygen, from water. In this report, we demonstrate the operation of a new water electrolysis cell at high inlet water pressure with the assistance of a hydrophobic gas diffusion layer (hydrophobic-GDL). This configuration allows the gas/water separation to take place at the electrode so that pressurized water-free gases can be the output due to water being injected directly into the membrane as a source of electrolysis for a continuous supply of water it prevents membrane dehydration. Another important feature is also the cell can be operable in a reversible operation by combining with fuel cell operation. The membrane electrode assemblies (MEAs) were prepared using the hydrophobic-GDL, a Nafion membrane, and Pt-C/IrO2 catalysts. Electrolysis experiments were performed at different temperatures with pressurized water (ΔP = 0.05–0.4 MPa based on atmospheric pressure) resulting output was pressurized (0.05–0.4 MPa) hydrogen and oxygen gases. The current densities at 1.6 V of electrolysis voltage were 117, 188, 262 mA cm−2 at 25, 60, and 80 °C, respectively, and the hydrogen and oxygen gas evolution rates were consistent with theoretical values.

In practice, its amount is significantly greater than its theoretical usage, often exceeding three times the theoretical amount. Hence, the presence of ultra-excessive nickel results in high material costs, posing obstacles to the wider implementation of Zebra batteries. To address this problem, we introduce hollow nickel source as active material to improve the nickel utilization in Zebra battery.
