Abstract:

In situ neutron diffraction was used to show that charge/discharge process of LiFePO 4 based real Li-ion battery can be effectively studied by time-of-flight technique at the IBR-2 pulsed reactor. The important option of the HRFD diffractometer is a possibility to utilize both high-intensity and high-resolution modes without any changes in the geometry of an experiment. The results clearly show that the kinetics of LiC n phase?s appearance and LiFePO4 ↔ FePO4 transformations are well observable and can be treated quantitatively.
