Web6 mrt. 2024 · Li- and Na-superionic ion-conducting ceramics find widespread use in lithium- and sodium-ion batteries as separators, solid electrolytes, and cathode materials. The ionic conductivity of these materials is influenced by crystal chemical parameters and can be further optimized via microstructural control using glass-ceramic processing. WebIonic crystals are included in this chapter since many, if not all, ceramics have some iconicity in their nature. Unlike pure metals, ceramics include at least two different species, such that vacancy formation is not of a single component. Therefore a vacancy may be a cation or an anion vacancy. These vacancies define a Schottky-type defect.
