Performance Benchmark of Planar Solid Oxide Cells Based on Material Development and Designs

“…For more detailed information on processing methods, the reader is referred to the relevant literature. [17,23,41,[53][54][55] What should be emphasized here is that processing predetermines the cell properties. The method itself, in combination with raw materials, their preconditioning, ink/ suspension formulation, processing parameters, and subsequent steps like thermal treatments critically affects the microstructure of the functional layers and thus cell performance and durability.…”

“…There are various excellent reviews and books available in the literature covering certain cell types, cell components, materials, manufacturing or mode of operation. [ 16,17,21–41 ] These articles provide detailed insights into reaction mechanisms, nanoscale material properties, degradation phenomena, and economics of operation to name just a few. The aim of this article is to present an overview of investigated material combinations and the obtained range of performance of planar SOCs, facilitating the assessment of the general potential of the cell types also for nonexperts.…”

Impact of Sandblasting on Morphology, Structure and Conductivity of Zirconia Dental Ceramics Material

“…Zirconia-based materials (e.g., Y-TSZ) can be also considered as oxygen-ion conductive solid electrolytes [17,25]. The presence of oxygen vacancies in Y-TSZ allows the diffusion of O 2− ions within the material [54]. The Y-TZS conductivity depends on the dopant type and concentration [55], as well as on the phase arrangement [18,25].…”

Ceramic materials for energy conversion and storage: A perspective

“…After the synthesis of ceramic powders (which is usually scalable, a clear advantage for oxide solid electrolytes for solid-state batteries for instance), numerous processing routes have been developed and are used in the industry for ceramic materials. We took recently the example of yttria-stabilized zirconia (YSZ) to show how both layer thickness from a few atomic layers to thick millimetric coatings and microstructure (from highly porous to fully dense) can be tailored by appropriate processing routes [9]. However, a considerable amount of know-how, not necessarily written in textbooks nor detailed in the scientific literature, is most of the time required for accurate control and reproducibility of the processes and resulting materials properties.…”

A practice-oriented, digital handbook or wiki of ceramic processing, summarizing decades of experience, would be very valuable to the scientific community and is to our knowledge still missing.…”
