Lithium ion secondary battery |
| abstract |
A lithium ion secondary battery that includes a positive electrode having a positive electrode mixture layer containing a positive electrode active material using a lithium-containing metal phosphate compound having an olivine structure and a conductive aid in a particulate form. Moreover, a negative electrode has a negative electrode mixture layer with a separator interposed between the positive and negative electrodes. The thickness of the positive electrode mixture layer is 75 μm or less. Furthermore, the positive electrode active material is formed from secondary particles having a diameter of 10 or less, with the secondary particles being formed by flocculating multiple primary particles having a particle size of 1 μm or less. The conductive aid has one or more constituent particles contained within a range of 5 μm from a center of the primary particle. |
