The invention relates to an electrode suitable for constructing an electrochemical double layer capacitor and/or supercapacitor and comprising as an electrode material a metal organic framework (MOF), wherein the MOF comprises an inorganic building unit comprising metal atoms selected from group 1 to group 12 elements, and functional groups of organic linkers comprising oxygen (O) and one or more atoms selected from the group comprising phosphorus (P), arsenic (As), antimony (Sb), silicon (Si), selenium (Se) and bismuth (Bi). In embodiments of the invention, the functional groups of the organic linkers are selected from the group comprising phosphonate, arsonate, phosphonic acid, phosphinic acid, arsonic acids and/or arsinic acids, monoester and/or diester forms thereof. Further, the metal atoms may be selected from the group comprising zinc (Zn), cadmium (Cd), copper (Cu), cobalt (Co), nickel (Ni), gold (Au) and silver (Ag). The invention further relates to an electrochemical double layer capacitor and a supercapacitor comprising an electrode of the invention.
