Surface treating method of negative electrode for magnesium secondary battery, negative electrode for magnesium secondary battery, and magnesium secondary battery

摘要

A surface treating method of a negative electrode for a magnesium secondary battery is provided, wherein the magnesium secondary battery includes: a negative electrode capable of releasing magnesium ions during discharging and capable of precipitating elemental magnesium during charging; a positive electrode capable of precipitating a magnesium oxide during the discharging and capable of releasing magnesium ions during the charging; and a non-aqueous ion conductor for conducting magnesium ions as conduction species. The surface treating method comprises initializing the negative electrode by performing the discharging to form a bare surface at a surface of the negative electrode.
