The structure of the solid aluminum capacitor is: the positive foil and the negative foil are respectively connected with the positive and negative guide pins, and the two are separated by the insulation material and overlapped and wound together, and are fixed by the tape, wherein the insulation material is a loose porous structure, The conductive polymer is filled; the wound structure is sealed by an aluminum casing and a rubber cover, and the guide pin communicates with the outside through the rubber cover.

　　Solid aluminum capacitor structure

The working mechanism is: the metal aluminum matrix of the positive foil is the positive electrode of the capacitor, the conductive polymer layer is the negative electrode of the capacitor, and the aluminum oxide film on the positive foil is the working dielectric; when the positive and negative guide pins are respectively connected with the positive and negative poles of the power source The positive pole of the capacitor is positively charged and the negative pole is negatively charged to store charge.

The shape of the solid aluminum capacitor is exactly the same as that of the liquid aluminum capacitor. The difference is that the solid aluminum capacitor uses a solid electrolyte (such as polypyrrole, polyaniline, PEDOT, etc.) instead of the electrolytic paper that adsorbs the electrolyte, so there is no need to change the circuit board structure. Replace liquid aluminum capacitors with solid aluminum capacitors as needed. Compared with liquid electrolytes, solid electrolytes have superior electrical conductivity and do not dry out like liquid electrolytes, so solid aluminum capacitors have excellent frequency characteristics and long life properties. PolyCap solid aluminum capacitors use the conductive polymer PEDOT as the electrolyte, which is currently the most advanced type of solid aluminum capacitor.
