Special Issue "Conducting Ceramics"
Deadline for manuscript submissions: 31 March 2020.
Interests: proton conducting ceramics; mixed electron-ion conductrs; perovskites; high-temperature superconductors; X-ray diffraction
Ceramics is traditionally considered as electrically insulating; however, several groups of modern advanced ceramics are conductors of electric currents. Among them, there are high-temperature superconductors, metal-like conducting ceramics, semiconductors, as well as ionically conducting ceramics. The electric and electrochemical properties of conducting ceramics, apart from their chemical composition, may depend strongly on their micro/nanostructure, porosity, defect interaction, redox processes, atmosphere composition, etc. Therefore, their properties may be modified through both powder fabrication and its densification and shaping into products. Moreover, many ceramic materials undergo structural phase transitions. The variety of phenomena related to charge transport in ceramics render them very interesting for practical applications. Indeed, conducting ceramics has been applied in superconducting electromagnets, gas sensors, solid oxide fuel cells, batteries, varistors, memory cells, and other electroceramic devices.
The Special Issue on “Conducting Ceramics” is intended to provide a unique interdisciplinary international forum aimed at presenting and discussing results concerning the fabrication, characterization, and properties of conducting ceramics as well as the characterization of devices based on conducting ceramics. Scientists working in a wide range of disciplines are invited to contribute to this Issue.
Examples of the topics that may be included in the Special Issue on “Conducting Ceramics” are listed under the keywords.

Abstract: All-solid-state batteries (ASSB) are considered promising candidates for future energy storage and advanced electric mobility. When compared to conventional Li-ion batteries, the substitution of Li-ion conductive, flammable liquids by a solid electrolyte and the application of Li-metal anodes substantially increase safety and energy density. The solid electrolyte Li1.3Al0.3Ti1.7(PO4)3 (LATP) provides high Li ion conductivity of about 10-3 S/cm and is considered as a highly promising candidate for both, the solid electrolyte-separator and the ionically conductive part of the all-solid state composite cathode, consisting of the cathode material, the solid electrolyte and an electron conductor. Co-sintering of the composite cathode is a sophisticated challenge, because temperatures above 1000 °C are typically required to achieve the maximum ionic conductivity of LATP but provoke reactions with the cathode material, inhibiting proper electrochemical functioning in the ASSB. In the present study, the application of sintering aids with different melting points and their impact on the sinterability and the conductivity of LATP is investigated by means of optical dilatometry and impedance spectroscopy. The microstructure of the samples is analyzed by SEM. The results indicate that the sintering temperature can be reduced below 800 °C while maintaining high ionic conductivity of up to 3.6 x 10-4 S/cm. These insights can be considered a crucial step forward to enable LATP based composite cathodes for future ASSB.
