Abstract: A negative active material for a rechargeable lithium battery includes a composite carbon particle including a core particle including crystalline-based carbon and a coating layer positioned on the surface of the core particle and including amorphous carbon. A peak intensity (I1620) at 1620 cm−1 ranges from about 0.01 to about 0.1, a peak intensity (I1360) at 1360 cm−1 ranges from about 0.05 to about 0.5, and a peak intensity (I1580 at 1580 cm−1 ranges from about 0.1 to about 0.8 in a Raman spectrum of the composite carbon particle.

Abstract: A secondary battery includes an electrode assembly including a first non-coating portion and a second non-coating portion, a first current collector and a second current collector joined to the first non-coating portion and the second non-coating portion, respectively, a case that accommodates the electrode assembly, and a cap assembly that seals the case. The first current collector includes a first overlapping portion that overlaps and joins the first non-coating portion, the first overlapping portion having a length and a width, and the first non-coating portion having a length and a width. The length of the first overlapping portion is 30% to 70% of the length of the first non-coating portion, and the width of the first overlapping portion is 50% to 70% of the width of the first non-coating portion.
