NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY AND LITHIUMSECONDARY BATTERY |
摘要 |
A negative electrode of a lithium secondary battery having a mixture layer containing graphite particles and an organic binder on a current collector, wherein the diffraction intensity ratio (002)/(110) of the mixture layer measured by X-ray diffraction is not higher than 500, and a lithium secondar y battery having that negative electrode and a positive electrode containing a lithium compound. Since the quick charge/discharge characteristics and the cycle characteristics do not deteriorate significantly when the negative electrode density of the lithium secondary battery is increased, a high- capacity lithium secondary battery having an enhanced energy density per volume of secondary battery can be provided. |
