By using the one-pot mechanical method，the layered rock-salt LiCoO2 powder was synthesized from Li2O and Co3O4 starting powders without any extra heat assistance. Processing time was only 15 min. The synthesized powders had the granule structure composed of primary nanoparticles. The solid-state synthesis of LiCoO2 from the same starting materials was also performed for comparison of powder properties. The calcination temperature to obtain LiCoO2 in the single phase was over 500℃ for 2 h. The BET equivalent diameters of the mechanically synthesized LiCoO2 powders was about 120 nm，which was close to that of the particles synthesized by solid-state reaction at 500℃.
