In the last few years there has been an increased focus on development of innovative, low-cost, efficient and durable materials for batteries and fuel cells. Electron microscopy and related techniques are at the forefront of this effort allowing scientist to gain fundamental understanding of the structure-property-performance relationship in these materials. This symposium will focus on advanced characterization methods for battery diagnostics and novel materials developments for battery applications. The topics will encompass using innovative materials diagnostic techniques including FIB sample preparation (cryoFIB, plasmaFIB, laser-PFIB), and 3D characterization, in-situ/in operando and cryo-TEM analysis, electrochemical analysis, XPS, and more.
