The present invention is related to ultracapacitors (or supercapacitors) and to the carbon electrode materials for ultracapacitors. A ultradocapacitor according to the invention comprises at least one pair of oppositely charged microporous carbon electrodes composed of an electrochemically active carbon material wherein an active carbon surface is modified with plurality of atoms or functional groups with a free electron pair covalently bound to hexagonal carbon, and an electrolyte containing ions forming an electrical double layer on the surface of electrically charged carbon electrode and a component changing a state of charge during recharging of the ultracapacitor. The carbon is preferably CDC (carbon derived carbon) activated by high temperature (600-1000&#xb0; C.) chlorine treatment.

Carbon electrode materials for pseudocapacitors and a pseudocapacitor

The present invention relates to an electric double-layer capacitor and its manufacturing method. The ultracapacitor comprises a cylindrical housing having a bottom at one end and the housing is closed by an end cap integrated with first current terminal. From the bottom of the housing protrudes a terminal end of the second current terminal. Unlike to the previously known solutions the current terminals are arranged into the ultracapacitor, and spot welded to the electrode terminal to decrease internal resistance and to reach optimal packing density.

Integrated carbon/carbon ultracapacitor of high power density and battery composed from said capacitors

This invention provides a method of manufacture of the electrochemical system of the electric double layer prismatic capacitor from electrically connected in parallel of semi-wound packages of micro/mesoporous carbon composite electrode pairs separated by porous cage. According to the method the pre-made carbon film will be covered with a layer of aluminum foil layer using a vacuum deposition method thus forming a current collector of an electrochemical system. Subsequently the pairs of electrodes are formed from a carbon composite electrode which are wounded or flipped to flat packages so that the ends of current collectors protruding from folded packages are joined together in parallel and thereafter the ends of current collectors are connected correspondingly to the positive and negative current terminal of the electric double layer capacitor.

Super capacitor of high specific capacity and energy density and the structure of said super capacitor

The present invention relates to the method of increasing the working voltage of electrical double layer capacitor with enhanced working voltage, which has electrodes fabricated from porous carbon powder in which the pore sizes and the specific surface are created by extracting the non-carbon atoms from the carbon-rich organic or mineral compounds. The method is performed by step-by-step treatment of supercapacitor with the conditioning voltage (Uc), which is increased gradually up to the working voltage (Uw) by the voltage step (DUc) which is less or equal to 0.2V.

Electrical double layer capacitor with enhanced working voltage

An electric double layer capacitor including at least one pair of polarizable electrodes connected to current collectors, a separator made of ion-permeable but electron-insulating material interposed between the electrodes in each pair of electrodes, and a liquid electrolyte. According to the invention the electrodes include a layer of carbon particles having a narrow distribution of nanopores therein, the pore sizes of the nanopores being adapted to fit the ion sizes of the electrolyte. The invention also relates to a method of manufacturing such a supercapacitor.
