[0020] Such as figure 1 A method for impregnating a capacitor element includes the following steps: 1) placing a conductive polymer monomer 3 in a vacuum furnace 2, and keeping the element 1 above the conductive polymer monomer 3;
[0021] 2) Seal the vacuum furnace 2, and pump the vacuum degree of the vacuum furnace 2 to 1×10 -4 Pa;
[0022] 3) Raise the temperature in the vacuum furnace 2 to 100°C and keep it for 5 minutes; then gradually lower the temperature in the vacuum furnace 2 to 50°C and keep it for 30 minutes;
[0023] 4) The element 1 impregnated with the conductive polymer monomer 3 is taken out of the vacuum furnace, and polymerized to generate PEDT after being impregnated with an oxidant.
[0024] In this embodiment, the conductive polymer monomer is EDOT and its derivatives. The oxidizing agent is aromatic iron sulfonate.
[0025] In this embodiment, step 3) can be repeated 1-3 times.
[0026] The impregnation method of the capacitor element in this embodi...
