PURPOSE: A cathode active material composition is provided to improve the stabilization of a battery by suppressing an electrical chemical reaction. CONSTITUTION: A cathode active material composition has a semiconduction characteristics by adding a semiconductor-being agent to a lithium compound oxide such as LiNO2, LiCoO2, LiMn2O4, and LiNi1-xCoxO2 so as to have such a positive temperature coefficient resistivity(PTCR) characteristics that a resistance is suddenly increased according to temperature increment over a predetermined temperature. The semiconductor-being agent comprises one selected from a group of Ba, Ti, Nb, Sb, Ta, Bi, La, Cs, Y, Pr, Nd, Sm, Gd, and Ho. |
