Electrode, a method for manufacturing the same, and an anode-free all-solid-state battery including the same

A method for manufacturing an electrode, the method comprising:

• manufacturing a coating solution by mixing magnesium particles, a carbon material, metal nanoparticles of a different kind from the magnesium particles, a binder, and a solvent;
• forming a coating layer on a surface of a current collector by using the coating solution;
• and
• drying the coating layer at a temperature of 100° C. to 150° C.,
• wherein a weight ratio of the magnesium particles to the metal nanoparticles of the different kind from the magnesium particles is 2.3 to 99.1.
