description 높은 초기 효율과 뛰어난 방전 용량 및 용량 유지율을 양립시킬 수 있는 이차전지용 음극 활물질, 음극 및 이차전지를 제공하는 것을 과제로 한다. 알칼리 금속 및 알칼리 토류 금속의 중 적어도 1종이 도핑된 제1 산화 규소 분말과, 도핑이 행해지지 않은 제2 산화 규소 분말을 함유하고, 제2 산화 규소 분말은 아몰퍼스인, 이차전지용 음극 활물질이 제공된다. A negative electrode active material for a secondary battery for achieving high initial efficiency and improved discharge capacity and capacity retention. The negative electrode active material for a secondary battery includes first silicon oxide powder particles doped with at least one of alkali metal or alkaline earth metal, and second silicon oxide powder particles, which are not doped, wherein the second silicon oxide powder particles are amorphous. A negative electrode and a secondary battery including the negative electrode active material are also disclosed.
