Boosting the interfacial superionic conduction of halide solid electrolytes for all-solid-state batteries.

ABSTRACT: Designing highly conductive and (electro)chemical stable inorganic solid electrolytes using cost-effective materials is crucial for developing all-solid-state batteries. Here, we report halide nanocomposite solid electrolytes (HNSEs) ZrO₂(-ACl)-A₂ZrCl₆ (A = Li or Na) that demonstrate improved ionic conductivities at 30 °C, from 0.40 to 1.3 mS cm^-1 and from 0.011 to 0.11 mS cm^-1 for Li⁺ and Na⁺, respectively, compared to A₂ZrCl₆, and improved compatibility with sulfide solid electrolytes. The mechanochemical method employing Li₂O for the HNSEs synthesis enables the formation of nanostructured networks that promote interfacial superionic conduction. Via density functional theory calc
