Calculations of Li-Ion Diffusion in Olivine Phosphates

Olivine phosphates are widely researched cathode materials for Li-ion batteries, because of their cyclability and stability over a wide range of temperatures. Lithiated iron phosphate (LiFePO4), which was first reported by Padhi et al., has a theoretical specific charge capacity of 170 mAh/g and a Fe redox couple at 3.5 V. LiFePO4 has an olivine structure… CONTINUE READING
