Our paper, Adaptively Driven X-Ray Diffraction Guided by Machine Learning for Autonomous Phase Identification, is published on npj Computational Materials.
Shown left: Conventional solid “ordered” electrolyte made of just one type of metal (blue spheres). The movement of lithium ions (yellow sphere) is slow and limited, thus hampering ion conductivity and battery performance. (Gray spheres represent oxygen.) Shown right: Ions move significantly faster through “disordered” solid electrolyte: Mixing different types of metals (blue, teal, and navy spheres) creates new pathways – much like the addition of expressways on a congested highway – through which lithium ions can move quickly through the electrolyte.
