Negative electrode for non-aqueous secondary battery

A non-aqueous electrolyte secondary battery comprising:

• a positive electrode;
• a negative electrode;
• a non-aqueous electrolyte between the positive electrode and the negative electrode;
• in which:
• the non-aqueous electrolyte comprises a non-aqueous solvent and lithium salt;
• the positive electrode comprises a positive electrode current collector, and, on the positive electrode current collector, a mixture comprising a positive electrode active material, a positive electrode conductive material, and a positive electrode binder;
• the positive electrode active material is a compound capable of occluding and of releasing lithium ions;
• and
• the negative electrode comprises a negative electrode current collector, and on the negative electrode current collector, a mixture comprising a negative electrode active material, a negative electrode conductive material, and a negative electrode binder;
• the negative electrode active material has the overall composition:
• AM1qM21-qOy;
• A is LiX or LiX-rGr, in which G is selected from the group consisting of Na, K, Cs, Be, Mg, Ca, Sr, Ba, and mixtures thereof, in which G and M1 are different;
• 0<x≦3;
• y is 3 or 4;
