Abstract: A nanosized particle has a first phase that is a simple substance or a solid solution of element A, which is Si, Sn, Al, Pb, Sb, Bi, Ge, In or Zn, and a second phase that is a compound of element D, which is Fe, Co, Ni, Ca, Sc, Ti, V, Cr, Mn, Sr, Y, Zr, Nb, Mo, Ru, Rh, Ba, lanthanoid elements (not including Ce and Pm), Hf, Ta, W or Ir, and element A, or a compound of element A and element M, which is Cu, Ag, or Au. The first phase and second phase are bound via an interface, and are exposed to the outer surface. The surface of the first phase other than the interface is approximately spherical. Furthermore, a lithium ion secondary battery includes the nanosized particle as an anode active material.
