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

开发新的阴极化学需要对结构和颗粒均一性有基本的了解，以便充分为最佳性能材料创造条件。对于存在无序的材料尤其如此，例如富锰的无序岩盐，或可能发生阳离子混合的系统，例如富镍的层状相或高压尖晶石。这名博士生将应用二次电子高光谱成像(SEHI)方法，这是一种新的空间分辨化学表征技术，可以实现纳米级分辨率，以评估未来之旅项目合成团队中出现的新阴极粒子。这些见解将有助于指导FutureCat项目中的材料合成方法，同时也代表着Faraday社区的高额回报成果，因为它展示了一种潜在的可广泛使用的技术，将有利于多个FI研究项目。

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.
