ABSTRACT:
A negative electrode material, a method for producing this material, and to a negative electrode and a lithium-ion battery comprising this material are described. The material comprises an active phase consisting of a material M based on Al, Si, Sn, Sb or a mixture thereof, and a support phase consisting of a material XaYbOc, where: O is an oxygen; Y is a cation with oxidation degree m=3, 4, 5 or 6; X is a cation with oxidation degree d=1, 2, 3, 4 or 5, X ensuring the electroneutrality of XaYbOc; and where: c is such that 2≦c≦10; b is such that 1≦b≦4; and a=(2c−bm)/d. An interface of mixed composition exists between the XaYbOc material and the active phase M, the interface consisting of the elements M, X, Y and O.
