An electrode for non-aqueous secondary batteries that is capable of intercalating and de-intercalating an alkali metal, such as lithium, and a non-aqueous secondary battery comprising the electrode are disclosed. The electrode comprises an electrode current collector, and, on the electrode current collector, an electrode active material. The electrode active material has the overall composition: SiaMbPc, in which 0<a<1, 0≦̸b<1, 0<c<1, and a+b+c=1; and M is selected from the group consisting of Mn, Co, Ni, Sn, Fe, and mixtures thereof. Depending on the redox potential of the other electrode in the battery, the electrode may be either a positive electrode (cathode) or a negative electrode (anode).
