Cold Sintering for High-Temperature Electrochemical Applications

Although cold sintering remains an emerging processing technique, it is noteworthy to consider recent progress in materials that are of interest to electrochemical systems with elevated service temperatures. Here we discuss a broad number of materials ranging from alkali electrolytes for solid state batteries, to oxygen ion conductors for gas sensing. We also discuss the opportunity to co-fire mixed ionic conductors into multilayered devices. Given the low-temperature sintering temperatures with the cold sintering process (CSP), we will discuss some insights into operating ceramics at temperatures near or above their processing temperature.
