Abstract: The present invention relates to a high-field anodization method using an electrolyte additive. According to the present invention, a nanostructure is formed in a metal surface by a high field anodic oxidation method for oxidizing the surface of the metal anode by dipping a metal anode and a counter electrode into an electrolyte of a anodization cell, and applying a voltage of a constant pattern between the metal anode and the counter electrode in the electrolyte. Moreover, a structure for a nanotemplate in which the nanostructure is self-aligned is formed by being anodic oxidized after mixing water and charcoal or lignite in the electrolyte, boiling the mixture by applying heat, and adding the extracted solution as an additive. The high-field anodization method using an electrolyte additive has the advantage of suppressing burning generated in applying a high voltage by adding a fixed amount of additives into an electrolyte, and manufacturing a nanotemplate with excellent self-alignment in a high voltage section.
