<P>PROBLEM TO BE SOLVED: To provide a negative electrode desirable for a lithium secondary battery in which decrease in a rapid charge-discharge behavior and a cycle characteristic is reduced when the negative electrode density is increased, and provide a high capacity lithium secondary battery in which the energy density per the volume of a secondary battery is improved. <P>SOLUTION: A negative electrode for a lithium secondary battery is formed by pressurizing and integrating the mixture of a graphite particle and an organic binder agent and a collector. In the negative electrode for a lithium secondary battery, a diffraction intensity ratio (002)/(110) measured by x-ray diffraction of the negative electrode is 500 or less. A lithium secondary battery includes the negative electrode for a lithium secondary battery, and a positive electrode including a lithium compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
