Negative Electrode For Lithium Secondary Battery, Method For Manufacturing Negative Electrode For Lithium Secondary Battery, And Lithium Secondary Battery Comprising Negative Electrode

Abstract: The present application relates to a negative electrode, a method for manufacturing the negative electrode, and a lithium secondary battery comprising the negative electrode, the negative electrode comprising: a negative electrode current collector layer; a first negative electrode active material layer provided on one surface or both surfaces of the negative electrode current collector layer; and a second negative electrode active material layer formed on the first negative electrode active material layer, wherein the second negative electrode active material layer satisfies a non-uniformity of formula 1 below. [Formula 1] 0 µm = l C-(A+B/2) l = 10 µm (In formula 1, A means the longest distance (µm) between a first surface and a second surface, B means the shortest distance (µm) between the first surface and the second surface, and C means the average thickness (µm) of the second negative electrode active material layer).
