Focused Ion Beam (FIB)/Scanning Electron Microscopy (SEM) is considered to be one of the most powerful techniques for three-dimensional morphological analysis and chemical composition characterization. It is widely used to study materials for energy applications and, coupled with computational analysis, it enables detailed 3D reconstructions of the examined sample. LiFePO4 (LFP) is an interesting cathode …

3D Tomographic Measurements And Simulations Of Li-Ion Battery Positive Electrodes
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. …

Lithium insertion/extraction kinetics in LiFePO4
The electric vehicle appears to be the new frontiers in lithium batteries. Distinctly different from mass produced microelectronics, it requires higher energy density as well as improved power performance requirements. Especially, charge/discharge rates during startup from standstill, deceleration, emergency charging, etc. provide unique challenges. To this end, new chemistries and new material with morphologies like …
