Title: Freeze-cast yttria-stabilized zirconia pore networks: Effects of alcohol additives

Abstract

Freeze casting yttria-stabilized zirconia (YSZ) can be useful in making electrodes for solid oxide fuel cells (SOFCs) by introducing hierarchical porosity to increase triple-phase boundary (TPB) area while maintaining adequate fuel flow. Here, in this work, the influence of alcohol additives on pore structure of aqueous YSZ freeze-cast samples was investigated. Slurries with ethanol, iso-propyl alcohol, or methanol as additives were compared to a control sample. Pore characteristics along sample lengths were measured using X-ray computed tomography reconstructions. The control sample showed significant changes in pore size along sample length, whereas pore size of the alcohol additive samples remained similar, indicating that freezing rates of the additive samples remained constant during solidification. Finally, ice lens formation and interactions between alcohols and slurry functional additives (dispersant, surfactant, and binder) resulted in complex pore structures which show promise in increasing SOFC TPB area.

Freeze-cast alumina pore networks: Effects of freezing conditions and dispersion medium

Journal Article Miller, S. M. ; Xiao, X. ; Faber, K. T. - Journal of the European Ceramic Society

Alumina ceramics were freeze-cast from water- and camphene-based slurries under varying freezing conditions and examined using X-ray computed tomography (XCT). Pore network characteristics, i.e., porosity, pore size, geometric surface area, and tortuosity, were measured from XCT reconstructions and the data were used to develop a model to predict feature size from processing conditions. Classical solidification theory was used to examine relationships between pore size, temperature gradients, and freezing front velocity. Freezing front velocity was subsequently predicted from casting conditions via the two-phase Stefan problem. Resulting models for water-based samples agreed with solidification-based theories predicting lamellar spacing of binary eutectic alloys,more »« less

Scalable Freeze-Tape-Casting Fabrication and Pore Structure Analysis of 3D LLZO Solid-State Electrolytes

Journal Article Shen, Hao ; Yi, Eongyu ; Heywood, Stephen ; ... - ACS Applied Materials and Interfaces

Nonflammable solid-state electrolytes can potentially address the reliability and energy density limitations of lithium-ion batteries. Garnet-structured oxides such as Li₇La₃Zr₂O₁₂ (LLZO) are some of the most promising candidates for solid-state devices. Here, three-dimensional (3D) solid-state LLZO frameworks with low tortuosity pore channels are proposed as scaffolds, into which active materials and other components can be infiltrated to make composite electrodes for solid-state batteries. To make the scaffolds, we employed aqueous freeze tape casting (FTC), a scalable and environmentally friendly method to produce porous LLZO structures. Using synchrotron radiation hard X-ray microcomputed tomography, we confirmed that LLZO films with porosities ofmore »« less

Pore narrowing and formation of ultrathin yttria-stabilized zirconia layers in ceramic membranes by chemical vapor deposition/electrochemical vapor deposition

Journal Article Cao, Guozhong ; Brinkman, H W ; Meijerink, J ; ... - Journal of the American Ceramic Society; (United States)

Chemical vapor deposition (CVD) and electrochemical vapor deposition (EVD) have been applied to deposit yttria-stabilized-zirconia (YSZ) on porous ceramic media. The experimental results indicate that the location of YSZ deposition can be varied from the surface of the substrates to the inside of the substrates by changing the CVD/EVD experimental conditions, i.e., the concentration ratio of the reactant vapors. The deposition width is strongly dependent on the deposition temperature used. The deposition of YSZ inside the pores resulted in pore narrowing and eventually pore closure, which was measured by using permporometry. However, deposition of YSZ on top of porous ceramicmore »« less
Dual Atmosphere Isothermal Aging and Rapid Thermal Cycling of Ag-Ni and Ag-CuO Stainless Steel to Zirconia Braze Joints

Journal Article Zhou, Quan ; Bieler, Thomas R. ; Nicholas, Jason D. - Journal of the Electrochemical Society

Silver—copper oxide brazes are commonly used to bond zirconia to stainless steel (SS) for Solid Oxide Fuel Cell (SOFC) and other high temperature joining applications. In fact, conventional Ag-CuO compositions (where Cu segregates to the surface, oxidizes, and reduces the silver wetting angle on zirconia from ~85 to ~40°) allow brazing to be performed in air. Unfortunately, the relatively high ~40° wetting angles of these reactive air brazes, and the ability of SOFC anode gases to reduce the CuO in them, produce pores during SOFC manufacturing and operation that reduce joint strength, impermeability, and longevity. Recently, Ag brazes utilizing transientmore »« less

Hybridization of Freeze Casting with Additive Manufacturing for Simplified Production of High Performance SOFCs

Technical Report Driscoll, David ; Sofie, Stephen

This report discusses research and development activities undertaken by Glacigen Materials, Inc. and Montana State University during the performance of a DOE Phase I STTR award. The objective of this project was to develop a manufacturing process by hybridizing the existing processes of freeze casting and additive manufacturing to enable facile and inexpensive production of high performance solid oxide fuel cells (SOFCs). The objective simultaneously addresses two barriers to the commercial implementation of SOFCs. First, the project demonstrates a method which allows SOFCs to be produced at dramatically decreased costs; and second, demonstrates a cell architecture which has the potentialmore »« less
