Abstract
LiCoO2 cathode materials with uniform gr ain size were prepared using fine grained CO3O4 particles. The effects of the molar ratio of Li/Co and the si ntering temperature on the microstructure (the grain size and its distribut ion) and the electric propel ties were studied. The AC impedance analysis i ndicated the presence of the secondary phases mainly at the gr ain boundary . The reversible Li+-intercalation/deintercalation capacity was also examin ed and the maximum value of 130 mAh g(-1) was obtained using the optimum pr eparation conditions.
