This research is part of Work Package 4 of the Faraday grant (Materials Design). The project involves the solution deposition of metal oxide films on NMC-811, with a particular focus on aluminium oxide. A further area of study will be the investigation of dopant metals within the oxide host, to counteract the degradation of the cathode sacrificially and in terms of solid-state metal-ion diffusion. Studies will start with commercial NMC-811 but move onto bespoke nano-particle samples in an effort to increase performance. The primary goal is to develop a scalable method of deposition that could be applied industrially, resulting in increased lifetime of the cathode. The programme will involve wet synthesis, solid-state characterisation of film morphology and electrochemical measurements of coin cells. Once a process is found which provides significant increase in lifetime, the programme will integrate with other aspects of the Faraday effort by exploring the performance of pouch cells.

这项研究是法拉第基金（材料设计）工作包4的一部分。该项目涉及在NMC-811上溶液沉积金属氧化物薄膜，特别关注氧化铝。研究的另一个领域将是氧化物主体内的掺杂剂金属的调查，以抵消阴极的牺牲和固态金属离子扩散方面的退化。研究将从商用NMC-811开始，但将转向定制的纳米颗粒样品，以提高性能。主要目标是开发一种可以在工业上应用的可扩展的沉积方法，从而增加阴极的寿命。该计划将涉及湿法合成，薄膜形态的固态表征和硬币电池的电化学测量。一旦发现一种能显著提高寿命的工艺，该计划将通过探索袋状电池的性能，与法拉第努力的其他方面相结合。
