Local structure within Li+ depleted LiFePO4

DOI

Lithium iron phosphate is a commonly used cathode material in Li-ion batteries. The material exhibits a two phase system on lithiation and delithiation with narrow solid solution ranges close to the two end phases, LiFePO4 and FePO4. Although the material is in widespread use, there is still a substantial lack of detailed understanding of the lithiation / delithiation mechanism. We believe that an analysis of the total neutron scattering from a partly delithiated samples of LiFePO4 will bring substantial increased knowledge regarding the structural mechanism of the Li ion transport. Especially in regards to the inter channel migration that is highly important for the Li ion transport. We will use total (Bragg plus diffuse) scattering to analyse the LiFePO4-FePO4 system.
