The chemo-mechano coupling at the electrode length scale is known to drive microstructure evolution resulting in performance loss. Recent efforts to incorporate these phenomena in microstructurally faithful 'Newman' type models has provided a nascent insight into the complex coupling between microstructure, chemistry and mechanical behaviour of particles and electrodes [Chung]. In this project, the student will explore the development and application of these image based modelling tools for a range of anode and cathode chemistries, providing crucial insight into electrode degradation, thereby also providing a crucial linkage between the modelling and degradation fast starts. Software tools: COMSOL/Abaqus. Interfaces with XP5, CC3

已知在电极长度尺度下的化学-机械耦合驱动微结构演变，导致性能损失。最近的努力，将这些现象在微观结构上忠实的“纽曼”型模型提供了一个新生的洞察微观结构，化学和颗粒和电极的机械行为之间的复杂耦合[钟]。在这个项目中，学生将探索这些基于图像的建模工具的开发和应用，用于一系列阳极和阴极化学，提供对电极退化的重要见解，从而也提供建模和退化快速启动之间的重要联系。软件工具：COMSOL/Abaqus。与XP 5、CC 3接口
