Lithium transition metal oxides, LiMO2, are the most promising positive electrode material for lithium ion batteries because of their high charge capacity (>150 mAh/g) and facile lithium ion diffusion in their lattice. A new synthetic method for preparation of stabilized LiMO2 has been developed as “<italic>Assisted Soft Chemistry</italic>.” Using this technique, the lithium in LiMO2 can be exchanged partially for zinc or gallium. Powder X-ray diffraction studies verify that zinc or gallium doped Li1−yZny/2MO2 and Li 1−yGay/3MO2, where ‘y’ equals 0.15 or 0.30 and ‘M’ is Co0.7Ni0.3, Co 0.3Ni0.7, or Ni have the same lamellar structure as their respective non-doped precursors, LiCo0.7Ni0.3O 2, LiCo0.3Ni0.7O2, and LiNiO2 . Observed electrical conductivities were determined by AC impedance spectroscopy and two point probe measurements and indicate marked electronic conductivity enhancement for the Zn substituted sample in the range of 1 to 2 orders of magnitude. Electrochemical charge/discharge profiles of the new cathode materials have shown reversible lithium insertion and extraction processes with charge capacity exceeding 150 mAh/g. The DSC analyses of the zinc-doped cathode materials show improved thermal stability of the new cathode materials when compared to non-doped commercial cathode materials.
