Exploring the Possibility of Extrinsic Anion Vacancies in Li6PS5Cl

Abstract The search for superionic conductors requires a deep understanding of the underlying crystal structure and local dynamic processes. Therefore, cationic and anionic substitutions are typically performed to monitor the resulting changes in the structure and ionic transport...

Operational Degradation of Flooded Lead–Acid Storage Under Frequency Containment Reserve: Long-Term Evidence from a Hybrid Multi-Technology BESS

Flooded lead–acid batteries continue to operate in utility-scale battery energy storage systems (BESSs), yet their long-term degradation under grid-frequency regulation remains poorly characterized by field evidence. This paper presents an eight-year, multi-indicator degradation...

Microstructural insights into fast ion transport in solid electrolytes via multiscale modeling

Abstract Improving solid electrolytes is critical for high-performance all-solid-state batteries, yet the microstructural features that enable fast ion transport remain poorly understood. Here, we use multiscale modeling to resolve polycrystalline ion transport from atomic-scale...
