As all-solid-state batteries (ASSBs) push toward higher energy densities, the limited oxidative stability of chloride solid electrolytes (CSEs) at ultrahigh voltages (>4.5 V) remains a critical bottleneck. Now, researchers from Shenzhen University, led by Prof. Guangliang Gary Liu and Prof. Wenjin Li, have introduced a ferroelectric BaTiO₃ (BTO) nanoparticle coating that significantly enhances the high-voltage stability of CSEs through interfacial electric field modulation.
