The invention relates to a process for the preparation of porous carbon materials, which particularly can be used in production of supercapacitors and Li-ionic current power supply. A process for the synthesis of porous carbon material from organic raw material of vegetable origin by means of two-stage pyrolysis, namely: by means of carbonization and activation, consists in that as initial raw material corn stigmas are used, at carbonization stage 4-5-times oxygen etching is carried out by bleeding in air to the operating area per 20-30 % from volume of loaded raw material, and at activation as an active reagent 2-3 M aqueous solution of potassium hydroxide (KOH) is used. The technical result consists in the increasing of specific capacity values to 254 F/g using the prepared material as electrode material in condensers on a double electrical layer (supercapacitor). |
