Functional ceramics play a key role in energy storage technologies such as all-solid-state lithium and sodium batteries. Traditionally, their processing relies on long and energy-intensive high-temperature sintering steps (700.1200\u00b0C for 12\u201348 h), which limit efficiency and restrict materials design. Ultrafast high-temperature sintering (UHS) has recently emerged as a disruptive alternative, enabling ceramic consolidation within seconds to minutes, drastically reducing energy consumption while minimizing unwanted reactions or degradation. This opens the possibility of combining materials that are typically incompatible under conventional furnace conditions.<\/p>\n\n\n\n

This PhD project will focus on the design, optimization, and application of UHS methods for state-of-the-art functional ceramics in batteries. The candidate will develop and test ultrafast sintering protocols for solid electrolytes, cathode composites, and mixed ionic\/electronic conductors. Emphasis will be placed on understanding and controlling densification, grain growth, and the integration of multilayered components, while systematically correlating sintering parameters, microstructure, and functional properties (e.g., ionic\/electronic transport, battery capacity).<\/p>\n\n\n\n

The ultimate goal is to fabricate a fully ceramic solid-state battery, in which all components are consolidated by UHS. This approach is expected to cut production times to below one hour, reduce energy consumption by more than 80%, and avoid degradation processes, thereby enabling superior battery performance compared to conventionally processed materials. Beyond this, UHS will serve as a platform for faster materials discovery and the accelerated deployment of next-generation energy technologies.<\/p>\n\n\n\n
