| description | The invention discloses a doped AB3 type hydrogen storage alloy, a negative electrode, a battery and a preparation method. The hydrogen storage alloy comprises a composition represented by RExGdyNizMnaAlbMcZrdTie; RE is selected from one or more of rare earth metal elements except Gd; M is selected from one or more of Cu, Fe, Co, Sn, V, W, Cr, Zn, Mo and Si elements; x, y, z, a, b, c, d and e represent the molar fractions of the elements respectively; the hydrogen storage alloy does not contain a metal element Mg; x is greater than 0, y is greater than 0.1, and x + y is equal to 3; a + b is less than or equal to 3 and is greater than 2, c is less than or equal to 2 and greater than or equal to 0, d + e is less than or equal to 3 and is greater than 0, and z + a + b + c is less than 9.5 andgreater than or equal to 7.8. The electrochemical performance of the doped AB3 type hydrogen storage alloy is improved.
