Figure 6: Particle fracturing in chemically delithaiated LixMn1.5Ni0.5O4 crystals.

(a) 3D surface renderings of two selected Mn1.5Ni0.5O4 crystals (the left one at ∼4 μm and the right one at 2 μm) show the formation of irregularly shaped cracks on the particle surface, (b,c) SEM images of pristine LiMn1.5Ni0.5O4 and delithiated Mn1.5Ni0.5O4 crystals, respectively. Scale bars, 1 μm (a–c).
