Abstract: A method and an apparatus for reducing the corrosion of a condenser in carbide derived carbons (CDC) production where cooling/quenching of a gaseous stream metal or metalloid halide is performed by direct contact of gaseous stream with liquid cooling agent before condenser, without utilizing a heat exchanger for the temperature range above 300° C., while keeping purity of gaseous stream of metal or metalloid halide constant. The apparatus comprises a reactor for carbide to carbon conversion and a condenser for collecting the by-produced metal- or metalloid chloride, and a cooling unit comprising a tank of liquid cooling agent. Temperature of the gas stream entering the condenser is reduced by heat absorbed in vaporization of a liquid metal- or metalloid halide introduced from the tank of liquid cooling agent through by supply pump, through the supply flow valve into the gaseous stream at the exit of the reactor.

Abstract: 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.

Abstract: The present invention concerns a method of manufacture of the homodispersed composite of the synthetic carbon material derived from carbide and silicon where the powder of the carbon material is first dispersed mechanically with the powder of silicon to homodispersed mixture, then the homodispersed mixture of the carbon material and silicon is sintered in an inert environment at a temperature between 1200 to 1500° C. to synthetic homodispersed composite of the silicon carbide and silicon. The homodispersed composite of the silicon carbide and silicon is heated in an inert environment at a temperature between 800 to 1100° C. and then the homodispersed composite of the silicon carbide and silicon is chlorinated at a temperature from 800 to 100° C.

Abstract: 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.
