Crystallographic electron microscopy
WebSelected area (electron) diffraction (abbreviated as SAD or SAED ), is a crystallographic experimental technique typically performed using a transmission electron microscope (TEM). It is a specific case of electron diffraction used primarily in material science and solid state physics as one of the most common experimental techniques. WebIt allows to effectively promote the crystallographic oriented Li plating along the (2 0 0) direction with the uniform spherical morphology instead of the hard whisker-like dendritic Li, as evidenced by the following X-ray diffraction (XRD), scanning electron microscopy (SEM), and density functional theory (DFT) calculation results.
