▎ 摘　　要

NOVELTY - The negative electrode comprises a negative electrode active material layer that is located on a surface of a current collector (200), and includes a negative electrode active material including magnesium-containing silicon oxides (100), a conductive material (110) including graphene (130) and single-walled carbon nanotubes (120), and a binder. The single-walled carbon nanotubes connect the magnesium-containing silicon oxide by line contact, and the single-walled carbon nanotubes are connected to each other through the graphene. The range of the band intensity ratio of the graphene is 0.8 to 1.5. USE - Negative electrode for lithium secondary battery (claimed). ADVANTAGE - The electrical network of the single-walled carbon nanotube expands two-dimensionally, and even when the silicon oxide contracts and expands, an electrical short circuit is prevented, thus exhibiting an excellent life improvement effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the negative electrode.
