Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

Claims

1. A multi-cell super capacitor of high operating voltage comprising at least two electrochemical cells (2) connected in series and placed into the external housing of the capacitor, whereas neighbouring cells are provided with a common current terminal, which is minus-terminal with regard to one cell and plus-terminal with regard to the other, with ends of the housing (1) being closed with covers (3, 4), onto which external current terminals (5, 6) have been installed and electrochemical cells have been separated from each other by a partition wall made of metal (7), whereas the maximum operating voltage of the super capacitor is approximately equal to the sum of the maximum operating voltage applied to the electrochemical cells being components of said super capacitor.

2. The super capacitor according to claim 1 , characterised by that the electrochemical cell consists of two or more pairs of electrodes that are separated from each other by ionic conductors and that contain at least 85% of carbon material of high specific surface area.

3. The super capacitor according to claim 1 , characterised by that the dimensions and energy specific characteristics of electrochemical cells are similar.

4. The super capacitor according to claim 1 , characterised by that there can be two or more electrochemical cells (2) connected in series into a common housing (1 ).

5. The super capacitor according to claim 1 , characterised by that the external housing of the super capacitor (1 ) is of cylindrical profile.

6. The super capacitor according to claim 1 , characterised by that the external housing of the super capacitor is of prismatic profile.

7. The super capacitor according to claim 1 , characterised by that the partition wall (7) is insulated from the super capacitor housing and electrochemical cells (2) are hermetically separated from each other by O-ring seals (11), placed between the partition wall (7) and super capacitor housing (1).

8. The super capacitor according to claim 1 , characterised by that current terminals (5, 6) are insulated from the super capacitor covers (3, 4) by an internal insulation washer 8 and insulation washer 15; and that current terminals (5, 6) are insulated from the super capacitor housing (1 ) by an external insulation washer (13), which has been placed around the base part of the current terminal (5, 6), located inside the super capacitor and between the internal wall of the super capacitor external housing (1 ).

9. The super capacitor according to claim 1 , characterised by that the external current terminals (5, 6) are electrically connected with electrochemical cells (2).
