Key Points

This study aims to understand the lithium deinsertion/insertion mechanism in LiFePO4 electrodes using high-resolution electron energy loss spectroscopy.
Utilized high-resolution electron energy loss spectroscopy on thin platelet-type particles of Li x FePO 4.
Investigated lithium deinsertion/insertion processes and their structural implications.
Analyzed compositions of LiFePO 4 and FePO 4 to reveal microstructural features.
Identified a core-shell structure of Li x FePO 4, with a core of FePO 4 and shell of LiFePO 4 based on composition x.
Showed that the lithium insertion process does not follow the classical shrinking core model.
Provided experimental evidence of distinct interfaces between single-phase areas of LiFePO 4 and FePO 4, not a solid solution.
