  "textContent": "In a non-aqueous electrolyte secondary battery, a positive electrode active material includes a carbon-coated lithium vanadium phosphate and a lithium nickel composite oxide. A negative electrode active material includes a carbon-based active material capable of intercalating and deintercalating lithium ions. When a first charge capacity of a negative electrode per unit area is \"x\" (mAh/cm 2 ), and a first charge capacity of a positive electrode per unit area is \"y\" (mAh/cm 2 ), a relation of \"x\" and \"y\" satisfies 0.6 ¤ y/x ¤ 0.92.",
