Multiscale microstructural design and engineering of lithium-ion battery electrodes

Speaker:  Xuekun Lu, UCL

Program Description:
Breakthroughs in the design and manufacturing of the next-generation lithium-ion batteries can further improve the market penetration of electric vehicles. Understanding the intricate physical and chemical processes across multiple length-scales is critical to assist the strategic design of electrodes for improved rate performance. Assisted by X-ray computed tomography and image-based modelling techniques, here we reveal the dependence of battery performance on the microstructure of the electrode from particle to the electrode scale, and microstructural evolution of the electrodes during manufacturing process. The influence of microstructural heterogeneities on battery performance is assessed. Distinct design strategies for energy and power-oriented cells are explained.
