Event Overview
The performance and safety of lithium-ion batteries (LIBs) are fundamentally linked to the structural and chemical stability of their electrode materials and electrolytes. This presentation explores the application of Raman spectroscopy as a non-destructive, high-resolution diagnostic tool for characterizing the electrode materials. Unlike traditional X-ray diffraction, Raman spectroscopy is very sensitive to local chemical environments, lattice dynamics, and amorphous phases, making it ideal for monitoring postsynthetic impurities, phase transitions, lithium-ion intercalation processes, and possible degradation mechanisms.
The presentation highlights the transition from static characterization to in situ and operando techniques, which allow for real-time observation of ionic transport and structural changes under actual operating conditions. By correlating Raman spectral changes with electrochemical performance, this diagnostic approach provides insights for optimizing material synthesis and further enhancing the energy storage safety.
