The mechanical properties of the key battery material NMC811 are determined by in situ compression. Individual single crystal particles withstand up to 14 GPa mean pressure, with highest loads to fracture perpendicular to the (0001)_NMC basal planes. In real-time, complex 3D fracture paths and particle rotation occur to compensate for lack of activation of 3D dislocation slip in the layered battery structure.
