Plasma Synthesis of Spherical Crystalline and Amorphous Electrolyte Nanopowders for Solid-State Batteries.

Here, we demonstrate the theory-guided plasma synthesis of high purity nanocrystalline LiSiPO and fully amorphous LiSiPON. The synthesis involves the injection of single or mixed phase precursors directly into a plasma torch. As the material exits the plasma torch, it is quenched into spherical nanocrystalline or amorphous nanopowders.
