Figure 5: Dislocations in both pristine and cycled LiNi1/3Mn1/3Co1/3O2 (NMC333).

High density of dislocations are shown in the bright-field images of (a) pristine and (b) cycled NMC333 (after 100 cycles at the high cutoff voltage of 4.7 V). (c) A HAADF image showing an end-on edge dislocation in pristine NMC333, (d) is the corresponding strain map by GPA and (e) shows the dislocation model of (c). Scale bars, 200 nm (a,b); 5 nm (c,d).
