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.
