Negative electrodes and non-aqueous secondary batteries that comprise the negative electrodes are disclosed. The electrode comprises a current collector; and a mixture on the current collector, the mixture comprising a negative electrode active material, a conductive material, and a binder. The active material has the overall composition: AM<SUP>1</SUP><SUB>q</SUB>M<SUP>2</SUP><SUB>1-q</SUB>O<SUB>y</SUB>; in which (1) A is Li<SUB>x </SUB>or Li<SUB>x-r</SUB>G<SUB>r</SUB>, in which G is selected from Na, K, Cs, Be, Mg, Ca, Sr, Ba, and mixtures thereof, in which G and M<SUP>1 </SUP>are different; (2) 0<=x<=3; 0<y<=3; 0<=q<=1; and 0<=r<=3; and (3) either M<SUP>1 </SUP>is selected from Sn, Mg, and mixtures thereof, and M<SUP>2 </SUP>is selected from V, Ti, Nb, Mn, Cr, Sb, Mo, Zr, W, and mixtures thereof; or M<SUP>1 </SUP>is selected from Y, Co, and mixtures of two or more of Y, Co, Sn, and Mg, and M<SUP>2 </SUP>is selected from Ti, Nb, Mn, Cr, Sb, Mo, Zr, W, and mixtures thereof.
