NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a negative electrode suitable for a lithium secondary battery with little deterioration in a boosting charge and discharge characteristic and a cycle characteristic when a negative electrode density is raised, and a high capacity lithium secondary battery with improved energy density per volume of the secondary battery.

SOLUTION: The negative electrode for the lithium secondary battery is comprised by pressurizing and integrating a collector and a mixture of graphite particles and an organic binding agent. It is characterized by that a diffraction intensity ratio (002)/(110) measured by X-ray diffraction of the negative electrode is ≤500, and it has a positive electrode including the negative electrode for the lithium secondary battery and a lithium compound.
