Postdoctoral Fellow in Zero-Excess Lithium Anode Sulfide-Based All-Solid-State Batteries

## Your tasks ##

* Develop and optimize zero-excess (anode-free) lithium metal sulfide-based all-solid-state batteries ASSBs for high-energy-density and safe applications

* Design and investigate current collector and interface engineering strategies, including thin-film surface modifications and protective interlayers to improve lithium plating/stripping reversibility

* Develop and optimize wet-slurry processing routes for the fabrication of sulfide-based composite cathodes and the manufacturing of multilayer pouch-cell ASSBs

* Perform comprehensive electrochemical characterization, including cyclic voltammetry, galvanostatic cycling, EIS, critical current density and Coulombic efficiency measurements

* Publish research findings in high-impact peer-reviewed journals

* Present results at international conferences and project meetings within the framework of collaborative industrial and academic research projects

## Your profile ##

* PhD degree in Electrochemistry, Materials Science, Inorganic Chemistry, Chemical Engineering, Physics, or a closely related field

* Proven hands-on experience with lithium metal and sulfide-based all-solid-state batteries ASSBs

* Strong expertise in the assembly, testing, and analysis of coin- and pouch-type ASSBs cells

* Experience with materials and electrochemical characterization techniques

* Demonstrated scientific publication record in the field of batteries or energy-storage materials

* Excellent communication skills and a strong command of spoken and written English
