Grain Boundary Dendrite Growth in Solid-State Electrolytes
Lithium dendrites growing through a solid electrolyte do not behave like the diffuse, roughly uniform plating seen at a liquid electrolyte interface. In a polycrystalline ceramic or a cold-pressed sulfide pellet, the microstructure itself dictates where lithium goes: dendrites overwhelmingly nucleate and propagate along grain boundaries rather than through the bulk of individual grains, even … Read more
