Olivine structured LiMPO4 (M = Fe, Mn, and Co) has attracted as considerable interest as a new class of cathode material for the next generation lithium ion battery because of their intrinsic merits: high theoretical capacity, excellent thermal stability, structural stability, environment friendly, and low material cost compared to commercial cathode materials. The substitution of anion, such as F-, I-, and BO33-, on phosphate site in olivine material had been prepared by solid state reaction without additional carbon sources. Samples were characterized by XRD, SEM, TEM with EDX mapping, XPS, galvanostatic charge-discharge testing, and solid-state NMR spectroscopy. All of prepared samples had shown enhanced initial discharge capacity and long cycleability. Details results with additional ongoing study will be discussed in the presentation.
