To provide an anode for a nonaqueous secondary battery of which anode activator is characterized by minimum volume change during absorption and release of lithium, high volume capacity, and high potential against metallic lithium.
On an anode and the nonaqueous secondary battery having the anode, the electrode is composed of a current collector and a mixture on the current collector. The mixture contains anode activator, conductive material, and binder. The activator has an overall composition expressed by AM1qM21-qOy. In formula, (1) A is Lix or Lix-rGr, wherein, G is selected from Na, K, Cs, Be, Mg, Ca, Sr, and Ba, or mixture thereof, Here, G and M1 are different from each other; (2) 0≤x≤3, 0<y≤3, 0≤q≤1, 0≤r≤3; and (3) M1 is selected from Sn, Mn, or mixture thereof, and M2 is selected from V, Ti, Nb, Mn, Cr, Sb, Mo, Zr, W or mixture thereof, or M1 is selected from Y, Co, and mixture of two or more kinds of Y, Co, Sn, and Mg, and M2 is selected from Ti, Nb, Mn, Cr, Sb, Mo, Zr, W, or mixture thereof.
