Abstract
The present disclosure relates to a negative electrode for an all-solid-state battery. The negative electrode includes a negative electrode current collector and a coating layer on the negative electrode current collector. The coating layer includes a carbon material, a metal, and a dielectric material. An amount of the metal is less than an amount of the carbon material, an amount of a dielectric material is less than an amount of the metal, and an amount of the dielectric material is in a range of about 1 wt % to about 10 wt % relative to a total weight of the coating layer.
