| description | The present invention provides a hydrogen storage material capable of improving the discharge characteristics of a nickel hydrogen secondary battery at low temperatures, and a negative electrode and a nickel hydrogen secondary battery using this hydrogen storage material. This hydrogen storage material contains hydrogen storage alloy particles and a surface modifier attached to the surface of the particles, and has a specific composition. In the X-ray diffraction pattern of this hydrogen storage material, when the relative intensity of the maximum peak Pmax among the diffraction peaks appearing in the range of 2θ = 42.00 degrees to 44.00 degrees is set to 100.00%, the relative intensity of the maximum peak P1 appearing in the range of 28 = 30.35 degrees to 30.65 degrees is from 4.00% to 70.00%, the relative intensity of the maximum peak P2 appearing in the range of 2θ = 32.85 degrees to 33.15 degrees is less than 60.00%, and the relative intensity of the maximum peak P3 appearing in the range of 2θ = 51.65 degrees to 51.95 degrees is less than 6.00%. |
