Abstract

Processes for the production of microporous carbon material, for use in electrodes of supercapacitors and secondary batteries, in which particulate metal carbide material is fluidized with a halogen gas at a high temperature in a fluidized bed reactor, the halogen gas is desorbed at a lower temperature of 150° C. to at most 250° C. under vacuum, and then the material is passivated using hydrogen gas and then milled.
