Original Abstract Submitted
A negative electrode active material for a secondary battery includes a negative electrode active material particle that includes a first object including a silicon oxide, and a second object including at least one of copper, a copper compound, tungsten, or a molybdenum oxide and attached to a surface of the first object. A Raman spectrum of the negative electrode active material particle has a maximum peak within a range of greater than or equal to 470 cmand less than or equal to 490 cm. An XRD spectrum thereof has a peak within a range of 37°±1° and a peak within a range of 44°±1°, has a peak within a range of 40°±1°, or has a peak within any one of a range of 23°±1°, a range of 25°±1°, a range of 37°±1°, a range of 41°±1°, a range of 54°±1°, or a range of 60°±10.
