Abstract
The present disclosure refers to a cathode material composite having improved conductivity, and a cathode and electrochemical device having the cathode material composite. In accordance with one embodiment of the present disclosure, a conductive polymer is positioned on the surface of a shell present in the form of a tetragonal structure in the lithium manganese oxide, thereby enhancing electrical conductivity to be highly involved in reaction around 3V, and providing a conductive path to improve the capacity, life and rate characteristics of an electrochemical device.
