Abstract: The present invention relates to a method for manufacturing of a porous electrode material, wherein the porous electrode material comprises transition metal phosphide on a porous structure comprising transition metal. The method comprises contacting elemental phosphorous and a porous structure comprising transition metal, and heating, in an inert atmosphere, the contacted elemental phosphorous and the porous structure comprising transition metal to a temperature in the temperature range of 300 to 1100° C., thereby reacting at least a part of the phosphorous and at least a part of the transition metal under formation of transition metal phosphide on the surface of the porous structure, thereby forming the porous electrode material. The present invention further relates to a porous electrode material obtainable by the method.
