| 摘要 |
The objects of the present invention are to provide a negative electrode for lithium secondary battery which can simultaneously satisfy high energy density and good charge/discharge cyclic characteristics, and to provide a lithium secondary battery which uses the negative electrode. The negative electrode of the present invention for lithium secondary battery contains natural graphite as an active material and contains a copolymer of polyvinylidene fluoride and hexafluoropropylene as a binder, wherein the graphite has an I[110]a/I[004]c ratio of 0.13 or more (wherein I[110]c is X-ray diffraction peak intensity of [110]c plane and I[004]c is that of [004]c plane, determined by X-ray diffraction 2&thetas;/&thetas; analysis of graphite relative to a principal plane of the electrode).
