The present invention relates to a metal storage host comprising: a three-dimensional structure including a carbonized material; and a transition metal distributed on the three-dimensional structure in a single-atom state, a cluster state of atoms, or a mixed state of the single-atom state and the atom cluster state; and a secondary metal battery including the same. Accordingly, the metal storage host of the present invention includes a carbonized material in which a transition metal is distributed in a single-atom state, a cluster state of atoms, or a mixed state of the single-atom state and the atom cluster state. Based on this structure, an anode of a secondary metal battery can be manufactured, thereby securing electrodeposition stability of the metal and suppressing dendritic growth of the metal. As a result, a secondary metal battery with high energy density and long cycle life characteristics can be achieved.
