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

摘要

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.

1. Method for manufacture of the electrochemical system of the super capacitor of high specific capacity and energy density, comprising manufacture of electrically connected in parallel of semi-wound packages of micro/mesoporous carbon composite electrode pairs separated by porous cage, including steps in which:
a) pre-made carbon film is dried in vacuum at up to 150° C. and is cut to the electrode dimensions, b) an aluminium layer is deposited to the carbon film by vacuum deposition method, forming a current collector, whereas, carbon film temperature is maintained during covering approximately same as that of the covered metal, whereas c) controlling of the aluminium coating contact is performed by reference voltage within the range of 50V to 20V, whereas
i) firstly, temperature is raised to up to 150° C. at highest reference voltage for additional degassing and disposing of light carbon particles, thenii) pores, grooves and gaps of the topmost particles of carbon film are filled with aluminium and theniii) reference voltage is reduced for completing the process of covering.
