However, NMC811 suffers from instability at high voltages which contributes to significant capacity loss, with the underlying degradation mechanism being poorly understood. We propose to use the capabilities of ID15-A to perform a complete in-situ structural study employing X-ray diffraction (XRD) and pair-distribution-function (PDF) computed tomography (CT) to elucidate a full understanding of the heterogenous structural changes throughout the electrode. During cycling of the cells, we aim to obtain spatially-resolved data to understand how local nano-crystalline phenomena propagate the onset of inactive phases, and how the thickness of the electrode promotes regional chemical environments facilitating inhomogeneous cell activity with complimentary tomographic techniques.
