POSITIVE ELECTRODE |
摘要 |
According to one embodiment, a positive electrode includes a positive electrode layer and a positive electrode current collector. The positive electrode layer includes a positive electrode active material including a first oxide represented by the following formula (α) and/or a second oxide represented by the following formula (&bgr;). The positive electrode layer has an intensity ratio falling within a range of 0.25 to 0.7. The ratio is represented by the following formula (1) in an X-ray diffraction pattern obtained by using CuKα radiation for a surface of the positive electrode layer. LixNi1-a-bCoaMnbMcO2   (α) LixNi1-a-cCoaMcO2   (&bgr;) I2/I1   (1)
