Abstract: The invention described herein is a process for the purification of carbon. That process provides for the treatment of carbon with hydrofluoric acid, or a mixture of hydrofluoric acid and nitric acid, followed in each case by treatment with hot aqueous hydrochloric acid. The carbon thus purified is notably effective for use as electrode material in a demineralization cell, i.e., one used for the demineralization of water.

Abstract: THE CAPACITY OF AN ELECTRICAL ENERGY STORAGE DEVICE CONTAINING A HIGH SURFACE AREA CARBON CATHODE, A METALLIC ANODE, AND A FUSED SALT ELECTROLYTE IN CONTACT WITH THE ELECTRODES, CAN BE GREATLY ENHANCED BY THE ADDITION OF A TELLURIUM COMPOUND DIRECTLY TO THE ELECTROLYTE OR TO THE CARBON CATHODE. ON PASSAGE OF AN ELECTRIC CURRENT THROUGH THE SYSTEM, THE TELLURIUM BECOMES PERMANENTLY BONDED TO THE CARBON OF THE CATHODE THEREBY FORMING AN "ACTIVE" TELLURIUM SPECIES THAT MANIFESTS ITSELF AS A CHARACTERISTIC PLATEAU IN THE DISCHARGE PROFILE OF THE CELL.
