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 12):
A method of fabricating the negative electrode for a secondary battery of  claim 1 , the method comprising:\n a step of forming a first negative electrode active material layer including a first negative electrode active material and a styrene-butadiene-based rubber on a negative electrode current collector; and a step of forming a second negative electrode active material layer including a second negative electrode active material and a (meth)acrylate-based polymer 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; a total content of a repeating unit of a styrene-derived structure and a repeating unit of a butadiene-derived structure in the styrene-butadiene-based rubber is 50 wt % or higher with respect to a total weight of the styrene-butadiene based rubber; and the (meth)acrylate-based polymer includes 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 %.
