SYTHESIS AND CHARACTERIZATION OF LiMnO₂ NANOPARTICLES

Orthorhombic LiMnO₂ nanoparticles have been synthesized through one-step hydrothermal method as a cathode material for lithium batteries. The synthesized material was characterized by scanning electron microscopy, energy-dispersive X-ray analysis, transmission electron microscopy, X-ray diffraction and the electrochemical impedance spectroscopy. The results showed that the size of nanoparticles is about 50 to 100 nm and the best d.c. conductance with the PVDF content of 2.5% is around 3.0 × 10⁻⁷
