High Performance Cathode-Electrolyte Interfaces for Solid Battery Systems
The HIGHCAT project investigates and engineers stable, low-resistance interfaces between high-voltage LNMO cathodes and garnet-type solid electrolytes (LLZO) to enable next-generation all-solid-state and hybrid lithium-ion batteries. Pulsed Laser Deposition is used for synthesizing dense LNMO cathode thin films, while Atomic Layer Deposition is employed to apply conformal protective coatings with nanometer precision. A broad range of binary and ternary oxide coatings are developed and evaluated for their chemical compatibility, redox stability, and interfacial resistance.
Current experimental work includes electrochemical characterization using cyclic voltammetry, galvanostatic charge/discharge cycling, and impedance spectroscopy on coated and uncoated cathodes. Both solid-state and conventional liquid electrolyte configurations are used in order to comparatively assess interfacial stability and electrochemical performance
