Hanyang University identifies 2.5 nm as minimum effective coating thickness for solid-state EV batteries

Summary

Researchers at Hanyang University determined that a minimum coating thickness of 2.5 nanometers is necessary for protective layers in sulfide-based all-solid-state batteries (ASSBs) to effectively suppress side reactions. This study provides a quantitative guideline for optimizing the cathode-electrolyte interface, potentially leading to longer-lasting batteries for electric vehicles. The findings were published in Energy Storage Materials and highlight the importance of precise coating thickness for battery performance.
