PROBLEM TO BE SOLVED: To provide a negative electrode for lithium secondary battery, using graphite particle suitable for a lithium secondary battery which is superior in quick charging and discharging characteristics and cycle characteristics with a small irreversible capacity of the first cycle, and a lithium secondary battery, using this negative electrode. SOLUTION: This negative electrode for lithium secondary battery is obtained by applying and integrating a graphite paste, obtained by adding and mixing an organic binder and a solvent to graphite particles in which two or more flat particles are made to collect or bond, so that the orientation face is nonparallel to a current collector. This lithium secondary battery is obtained, by arranging this negative electrode for lithium secondary battery and a positive electrode in opposition to each other via a separator, and injecting an electrolyte to the circumference thereof. |
