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.

开发新的阴极化学物质需要对结构和颗粒均匀性有基本的了解，以便充分建立最佳性能材料的条件。这对于存在无序的材料尤其如此，例如富锰无序岩盐，或者可以发生阳离子混合的系统，例如富镍层状相或高压尖晶石。该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，可以实现纳米分辨率，以评估FutureCat项目合成团队中出现的新阴极颗粒。这些见解将有助于指导FutureCat项目中的材料合成方法，同时也代表了法拉第社区的高回报成果，展示了一种潜在的广泛使用的技术，这将有利于多个FI研究项目。
