Note sull'episodio
In this episode, we talk with Dr. Sara Drvarič Talian from the Department of Materials Chemistry at National Institute of Chemistry about how operando impedance spectroscopy is transforming battery research. We explore her team’s recent Nature Communications study demonstrating how real-time impedance measurements in three-electrode cells can reveal the dynamic processes inside lithium metal batteries, from lithium diffusion and surface changes to dendrite formation. Sara explains how this approach overcomes the limitations of conventional equilibrium-based impedance techniques and why tracking these processes operando is critical for understanding failure mechanisms such as internal short circuits and lithium pitting. From innovative experimental design to perspectives on safer, high-performance batteries, this conversation connects electrochemi ...
