Abstract

The present disclosure relates to a negative electrode, a secondary battery including the same, and a secondary battery system for the same. The negative electrode can implement a predetermined volume resistance by including aluminum-containing particles of specific components and a conductive material in a coating layer. Such a negative electrode can implement appropriate insulating properties on the negative electrode surface during an internal short-circuit while allowing a predetermined current to leak, thereby preventing melt-down phenomenon and/or rapid heat generation of the secondary battery due to internal short circuits.
