LITHIUM ION SECONDARY BATTERY |
| 摘要 |
A lithium ion secondary battery includes a positive electrode that includes a positive electrode active material layer; a negative electrode that includes a negative electrode active material layer; and a nonaqueous electrolyte. The positive electrode active material layer contains an inorganic phosphate compound and a high-potential positive electrode active material that causes an open-circuit voltage to be 4.3 V or higher with respect to lithium metal. The inorganic phosphate compound is a compound containing at least one hydrogen atom in a chemical formula. |
