A calcium-cobalt oxide anode material is provided to ensure capacity higher than that of a conventional carbon material, stable cycle property, and excellent lithium ion conductivity. A calcium-cobalt oxide anode material has a composition of the chemical formula 1: [(Ca_(3-x).A_x)(Co_(4-y).B_y)O_9. In the chemical formula 1, A is an inert element selected from Bi, Gd and Na; and B is the transition elements selected from Fe, Ni, Mn and Cu, and 0<=x<=1, 0<=y<=1. |
