Engineering cathode particle (in-)homogeneity through Secondary Electron Hyperspectral Imaging

点击翻译按钮获取中文摘要

Exploiting new cathode chemistries requires a fundamental understanding of structure andparticle homogeneity in order to fully establish conditions for best performing materials. This isparticularly true for materials where disorder exists, e.g. the manganese-rich disordered rocksalts, or systems where cation mixing can occur, e.g. nickel-rich layered phases or the highvoltage spinels. This PhD student will apply Secondary Electron Hyperspectral Imaging (SEHI)methods, a new spatially-resolved chemical characterisation technique which enables nanometerresolution, to evaluate new cathode particles emerging from the synthetic teams on the FutureCatproject. Such insights will help to steer materials synthesis approaches in the FutureCat project,while also representing a high-reward outcome for the Faraday community in terms ofshowcasing a potentially widely-accessible technique that would be of benefit for multiple FIresearch projects.
