The invention provides a three-dimensional porous metal material which comprises a three-dimensional metal inner core and a metal adhesion layer, the three-dimensional metal inner core is coated with the metal adhesion layer, and the surface density value of the metal adhesion layer in the width direction of the three-dimensional metal inner core is in wavy distribution. The material gives consideration to optimal combination of conductivity, density, specific surface area and pore structure; according to the method for preparing the three-dimensional porous metal material, only the anodes in the electroplating process need to be replaced with the movable anode set, corresponding positions are arranged, additional production equipment and steps do not need to be added, deposition metal consumed in the production process is less than that in the prior art, and the cost is effectively reduced; the three-dimensional porous metal material is cut into a current collector containing a half surface density waveform
