The present disclosure relates to a metal air filter including: a filter which is formed of a metallic material by electrodeposition and has a nano branch structure; an ionizer which conducts particles to be captured by the filter with negative charges; and a power supply which supplies a positive voltage for conducting the filter with positive charges and a negative voltage for the ionizer. The filter can be more simply manufactured at a lower cost than a conventional process.

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.
