  "textContent": "Provided is a positive electrode for a secondary battery, which has a small change in a crystal structure due to charging and discharging and has excellent cycle performance. The positive electrode for a secondary battery includes n positive electrode active material layers (n is an integer greater than or equal to 2), n−1 separation layer(s), and a positive electrode current collector layer. The positive electrode active material layers and the separation layer(s) are alternately stacked. The positive electrode active material layer contains lithium, cobalt, and oxygen. The separation layer contains a titanium compound. Titanium oxide and titanium nitride are preferable as the titanium compound, and titanium oxide is particularly preferable.",
