NANOCOMPOSITE ELECTROCHEMICAL CAPACITOR AND ITS MANUFACTURING METHOD Russian patent published in 2014 - IPC H01G11/34 H01G11/54 H01G9/15 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, particularly to manufacturing of electrochemical capacitors. A nanocomposite electrochemical capacitor consists of two or more electrodes, electrolytes, separators and current collectors placed in the temperature-controlled space; at that each pair of electrode and electrolyte is represented as nanocomposite made of nanocarbon material and solid ionic organic or inorganic compound of eutectic composition, at that electrodes are made of nanocarbon material with specific area more than 1300 m²/g in the form plates or sheets with thickness of 0.1-10 mm and density of 0.8-1.2 g/cm³. The method of capacitor manufacturing includes dispersion of the prepared electrode mixture with binding agent; moulding of plates or sheets out of dispersed electrode mixture with binding agent, annealing of moulded plates or sheets in oxidising and/or deoxidising atmosphere or under vacuum and impregnation of compacted electrodes in fused bath or electrolyte solution at high temperature and under vacuum with further cooling.

EFFECT: improved specific energy capacity of the claimed capacitor is the technical result of this invention.
