Lithium ion secondary battery |
| abstract |
An object of the present invention is to provide a lithium-ion secondary battery having excellent rate characteristics and less deterioration in charge/discharge capacity even after repeated high-speed charge and discharge. The lithium ion secondary battery of the present invention has a positive electrode including a positive electrode active material, a negative electrode including a negative electrode active material, and a non-aqueous electrolyte. The positive electrode active material is a lithium transition metal oxide and a lithium-containing transition metal phosphate compound. The negative electrode active material is an organic sulfur-based electrode active material. It is suitable that the lithium transition metal oxide is a lithium cobalt-based oxide or a lithium nickel-based oxide. It is also suitable that the ratio of the number of moles of phosphorus to the total number of moles of transition metals contained in the positive electrode active material is 0.0001 to 0.2. |
