摘要：
A negative electrode active material of lithium secondary battery include: at least one of a petroleum-derived green coke and a coal-derived green coke, and at least one of a petroleum-derived calcined coke and a coal-derived calcined coke within a mass ratio range of 90:10 to 10:90; a phosphorous compound within a range of 0.1 to 6.0 parts by mass in amount equivalent to phosphor relative to 100 parts by mass of the at least one of the green cokes and the at least one of the calcined cokes; and a boron compound within a range of 0.1 to 6.0 parts by mass in amount equivalent to boron relative to 100 parts by mass of the at least one of the green cokes and the at least one of the calcined cokes.
