This talk reviews the use of focused ion beam – scanning electron microscopy (FIB-SEM) and transmission X-ray microscopy (TXM) to obtain three-dimensional tomographic images of commercial lithium-ion battery electrodes such as LiFePO4, LiCoO2, and LiCoO2/Li(Ni1/3Mn1/3Co1/3)O2 composite. After briefly reviewing the measurement techniques, the structural results are described, including imaging of both oxide and carbon phases. …
