Interlayer-Confined LiNO 3 Reservoir Enables the Formation of a Li-Containing Hybrid SEI for Robust Sodium Metal Anodes.
Sodium metal batteries hold great promise for energy storage applications, but are constrained by limited charge transfer kinetics and unstable solid electrolyte interphases (SEI). Here, we construct a montmorillonite-based sustained-release separator by confining LiNO 3 within interlayer galleries and integrating it o...
