Microstructural Characterization of Lithiated Graphite

Abstract

The microstructures of lithiated graphite were studied using high‐resolution transmission electron microscopy (HRTEM) and x‐ray diffraction (XRD). HRTEM shows lattice images of the (001) layers of with layer spacing of 3.70 Å, consistent with XRD. The morphology and distribution of the and phases were investigated by dark field image and selected‐area electron diffraction in TEM. The results indicate that and phases can coexist in the lithiated graphite particle.
