What is the role of anion redox in the electrochemistry of oxysulfide cathode materials?

硫氧化物材料提供了一种通向地球丰富的覆盖材料的途径，而没有与纯氧化物或较低容量的纯硫化物相关的问题。此外，双阴离子正极材料比其他理论上的高容量正极材料具有更高的稳定性和更高的安全性。第一种这样的材料开始出现，虽然它们目前还不能与当前领先材料的性能相匹配，但它们的后代有可能成为电网和汽车电池应用的廉价替代品。该项目将进行高通量计算计算以及统计力学建模，以了解当前一代硫氧化物阴极材料合成和操作的基础物理和化学，以及未来几十年将定义相关发展的更广泛趋势。Saiful Islam教授是计算材料科学领域的领先专家，他的经验和丰富的知识将有助于与摩根博士一起指导该项目。伊斯兰教授在将尖端实验和计算材料科学联系起来方面具有很强的专业性，预计他将在将本研究的结果与英国和世界各地的实验合作者的结果结合起来方面发挥关键作用，从而形成令人信服的叙述，大大增加该项目的影响力。尽管伊斯兰教授和摩根博士有着很强的合作研究记录，但他们有着不同的学术背景，在我的培训中，他们为我提供了不同的观点和哲学。摩根博士和伊斯兰教授将分别承担70%和30%的监督贡献。该项目与法拉第电池挑战赛及其开发下一代能源储存和运输材料的目标保持一致。反过来，这与EPSRC的核心使命密切相关，EPSRC在发展英国知识和领导力方面具有经济，社会和科学意义的物理科学前沿，以及EPSRC的目标是培训ECR与科学和工业努力相关的技能。

Oxy-sulphide materials provide a route to earth abundant covered materials without the associated problems with pure oxides or the lower capacity pure sulphides. Further to this, bi-anionic cathode materials hold the possibility of higher stability and greater safety than other theoretical high capacity cathode materials. The first such materials are starting to emerge and while they do not at present match the properties of current leading materials their descendants have the potential to be cheap alternatives for both grid and automotive battery applications. This project will perform high throughput computational calculations alongside statistical mechanical modelling to understanding the fundamental physics and chemistry which underlies the synthesis and operation of both the current generation of oxysulfide cathode materials, and the broader trends which will define related developed over the coming decades.Prof. Saiful Islam is leading expert in computational materials science, his experience and wealth of knowledge will assist in steering the project alongside Dr Morgan. Prof. Islam has a strong specialism in linking cutting edge experimental and computational materials science and it is envisaged that he will play a key role in combing the results of this study with those of experimental collaborator in Britain and throughout the world into a compelling narrative, massively increasing the impact of the project. In spite of their strong collaborative research record Prof. Islam and Dr Morgan have different academic backgrounds providing me with the benefit of diverse opinions and philosophies in my training. The split in supervisory contributions will be 70% Dr. Morgan and 30% Prof. Islam.This project aligns well with Faraday Battery Challenge and its aims of developing next generation materials for the storage and transport of energy. In turn this aligns strongly with core mission of EPSRC in developing British knowledge and leadership in economically, societally, and scientifically significant frontiers of the Physical Sciences, as well as EPSRCs aims in training ECRs with skill sets relevant to both scientific and industrial endeavors.
