    Abstract: The present invention relates to a cathode material for a non-aqueous lithium secondary battery using spherical porous cobalt oxide and a manufacturing method thereof. The lifetime characteristics of the final cathode material can be improved by inhibiting the structural collapse of the final cathode material at a high voltage because the spherical porous cobalt oxide including nanosized titanium dioxide uniformly is manufactured using a sedimentation reaction in a liquid state. According to the present invention, the spherical cobalt oxide in a size of 5 to 25 μm can be manufactured by the sedimentation of a cobalt material, a hydroxyl group material, a dissimilar metal material for substitution and an ammonia material so as to have a composition ratio of Co1-xTix(OH)2 (0.00
