| Abstract: | A series of novel cathode materials for lithium ion batteries, Li-contained phosphates LiMPO_4 (M=Fe, Mn), were synthesized by solid state reaction or wet chemical method. Powder X-ray diffraction patterns indicate the as-prepared samples are all pure phases. Raman and FTIR spectroscopic studies of these materials were carried out and the vibrational bands were assigned. Cyclic voltammograms indicate that the Li-contained phosphates can serve as cathode materials for lithium ion batteries. |
