NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY |
摘要 |
A negative electrode for a lithium secondary battery, comprising a layer of a mixture containing graphite powder and an organic binder on a current collector, wherein a diffraction intensity ratio (002)/(110) measured by X-ray diffractometry of the layer of a mixture is 500 or less,
and a lithium secondary battery, comprising the negative electrode for a lithium secondary battery, and a positive electrode that includes a lithium compound. It results less deterioration in the rapid charge and discharge characteristics and the cycle characteristics when the density of the negative electrode is made higher. Thereby it provides a high capacity lithium secondary battery having the improved energy density per unit volume of the secondary battery. |
