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, wherein the CNT film includes a number of CNTs packed closely, entangled and interconnected with each other, and disorderly arranged. The electrolytic capacitor is a high-performance capacitor.
