Figure 4

The NMC333 particles are cycled 100 times with the high cutoff voltage of 4.7 V. In a–d, the arrows highlight the crack tips that are terminated in grain interior, and (e) a schematic diagram showing crack formation in the grain interior due to tensile stress. Scale bars, 100 nm (a,b); 200 nm (c); and 50 nm (d).
