Abstract: The present disclosure relates to manganese oxide nano-rods in the form of a core-shell, in which the manganese oxide nano-rods are formed in a core-shell structure, the core and the shell each include MnxOy, when x of MnxOy of the core is 1 and y is 2, x of MnxOy of the shell is 2 and y is 3, and when x of MnxOy of the core is 2 and y is 3, x of MnxOy of the shell is 1 and y is 2. According to the present disclosure, in the secondary battery using the manganese oxide, the elution of manganese is inhibited and the structural stability of an active material is increased, thereby increasing the capacity and the cycle life at a high temperature.
