Abstract: The present disclosure relates to an anode for a lithium-metal battery, a manufacturing method of the same, and a lithium-metal battery including the anode. The anode for a lithium-metal battery includes a complex hierarchical structure current collector which includes an inverted pyramid-shaped micro hole pattern and nanostructures provided within the inverted pyramid-shaped micro hole pattern; and a lithium metal which is electrodeposited on the nanostructure of the current collector. As a result, it is possible to increase the life stability of the battery and increase the coulombic efficiency.
