Abstract:
The present invention provides a negative electrode for a secondary battery, the negative electrode including a negative electrode current collector, a first negative electrode active material layer located on the negative electrode current collector, and a second negative electrode active material layer located on the first negative electrode active material layer, such that resistance in the electrode is decreased due to an increase in adhesion between the negative electrode current collector and the active material and cohesion between the active materials, thereby significantly improving capacity and lifespan characteristics of a battery, a method of fabricating the same, and a secondary battery including the same.

Claim (Index 1):
A negative electrode for a secondary battery, the negative electrode comprising:\n a negative electrode current collector; a first negative electrode active material layer located on the negative electrode current collector; and a second negative electrode active material layer located on the first negative electrode active material layer, wherein: a ratio of a thickness of the first negative electrode active material layer to a total thickness of the first and second negative electrode active material layers is less than 0.5; the first negative electrode active material layer includes a styrene-butadiene-based rubber in which a total content of a repeating unit of a styrene-derived structure and a repeating unit of a butadiene-derived structure is 50 wt % or higher; and the second negative electrode active material layer includes a (meth)acrylate-based polymer including a repeating unit of a styrene-derived structure and a repeating unit of a (meth)acrylic acid ester-derived structure, the repeating unit of the (meth)acrylic acid ester-derived structure being included in an amount of 60 wt % to 90 wt %.
