Wound lithium-ion secondary battery |
| abstract |
(57) [Problem] To provide a wound lithium ion secondary battery having high voltage and good load characteristics. SOLUTION: In a wound lithium ion secondary battery in which a lithium transition metal oxide is used as a positive electrode active material and a carbon material capable of doping / dedoping lithium ions is used as a negative electrode active material, the interlayer distance d 002 in the positive electrode is reduced. Carbon A having a crystallite size Lc in the c-axis direction of 400 ° or more and carbon B having an interlayer distance d 002 of 3.70 ° or more and a crystallite size Lc in the c-axis direction of 250 ° or less is used. The amount of the electrolyte is adjusted to 15% by weight to 33% by weight based on the total amount of the positive electrode active material and the negative electrode active material. It is preferable that the porosity in the positive electrode is 28% by volume to 40% by volume. |
