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.

The present invention relates to a composition for a solvent-free electrode binder, an electrode comprising the same, and a method for manufacturing the same. The composition for a solvent-free electrode binder according to the present invention can improve mixing uniformity during the electrode mixing process and enhance the interfacial stability between the current collector and the electrode, thereby improving the performance of the electrode and the battery.

The present invention relates to a cationic polymer electrolyte and a method for preparing the same, wherein the polymer electrolyte of the present invention exhibits excellent ion transport properties.
