ABSTRACT:
An electrolytic capacitor includes a first electrode, a second electrode opposite to the first electrode, a separator sandwiched between the first electrode and the second electrode, a cell accommodating the first electrode, the second electrode and the separator, and an electrolytic solution filled into the inner space of the cell, with the first electrode, the second electrode and the separator immersed into the electrolytic solution. The first electrode and second electrode are in a CNT film structure, and the CNT film structure includes a number of CNT films stacked and packed closely by van der Waals attractive force. Each CNT film includes a number of aligned CNTs, and an angle between the aligned directions of CNTs of any two adjacent CNT film is in an approximate range from 0 to 90 degrees. The electrolytic capacitor is a high-performance capacitor.
