In these images we can observe stripe features in the c-axis of the particle. In addition, the outside of the particle exhibits a shorter c-axis than the inside of the particle. These stripe features bear a striking resemblance to the gliding planes recently described by Bi et al.. Glide plane defects and periodic kinking have been re-ported in several high-resolution TEM studies on NMC. Using the sodiated structure, Li et al. showed that this bending accumulates planar dislocations and kinks with a periodicity of 430±40 nm, which is in excellent agreement with the ca. 440 nm period of the stripes in Fig- . These defects readily nucleate microcracks and irreversible phase transitions during charging and are responsible for capacity degradation of the active material. In addition to creating lattice distortion, Lin et al. showed that these planar dislocations also induce Ni-Li antisite disordering, linked to structural instability. Since the scattering power of Ni and Li are very different, local variation in site mixing may explain why the stripe features are also visible in the diffracted intensity map (Fig. ).
