Abstract

A negative electrode for a secondary battery according to exemplary embodiments may include: a negative electrode current collector; a first negative electrode active material layer formed on at least one surface of the negative electrode current collector and including a first negative electrode active material which contains at least one of a first carbon-based active material or a first silicon-based active material; and a second negative electrode active material layer formed on the first negative electrode active material layer and including a second negative electrode active material, which contains at least one of a second carbon-based active material or a second silicon-based active material, and a conductive polymer. Accordingly, resistance can be reduced without increasing the content of a conductive material, and rapid charging performance can be improved.
