The student will contribute to the development of new standard test protocols for evaluating Li (and post Li) batteries. This will develop robust standards for electrochemical characterisation and accelerated stress tests to provide an enhanced toolbox for standard characterisation of batteries and materials. Particular impact will be derived by the NEXTRODE programme where we will seek to rapidly evaluate materials from the programme, and provide robust benchmarking of performance versus the current state of the art.The student will contribute to the development of advanced materials characterisation tools and establish protocols to translate these tools to a production environment. Alongside robust electrochemical benchmarking, the tools for electrode design will include advanced X-ray imaging and image based modelling and will provide unprecedented understanding of the performance/microstructure relationship. Translating this understanding to a production environment remains challenging; this raises the question. how will we know that our design intent has been effectively implemented? To address this the student will contribute to the design of 'proxy' measurements for electrode quality which can be applied in-line; these include electrical, acoustic, optical and X-ray measurements, which can be rapidly applied in the manufacturing process providing robust quality control, and verification of design hypotheses.

学生将有助于评估锂（和后锂）电池的新标准测试协议的开发。这将为电化学表征和加速应力测试开发强大的标准，为电池和材料的标准表征提供增强的工具箱。NEXTRODE计划将产生特别的影响，我们将寻求快速评估计划中的材料，并提供与当前最先进的性能的强大基准。学生将有助于开发先进的材料表征工具，并建立协议，将这些工具转化为生产环境。除了强大的电化学基准测试外，电极设计工具还将包括先进的X射线成像和基于图像的建模，并将提供对性能/微观结构关系的前所未有的理解。将这种理解转化为生产环境仍然具有挑战性;这就提出了一个问题。我们如何知道我们的设计意图已经有效地实现了？为了解决这个问题，学生将有助于电极质量的“代理”测量的设计，可以在线应用;这些测量包括电气，声学，光学和X射线测量，可以快速应用于制造过程，提供强大的质量控制和设计假设的验证。
