Description

Super capacitor module

The invention relates to a super capacitor module.

Supercapacitors, also known as Electric Double-Layer Capacitors (EDLCs), are a new type of energy storage device. The energy storage mechanism of a supercapacitor is between a conventional capacitor and a battery. When current is charged to the electrodes of the supercapacitor, the charge on the surface of the electrode will attract the opposite ions in the surrounding electrolyte such that these ions adhere to the surface of the electrode to form an electric double layer. Since the distance between the two charge layers is very small, the electric double layer is caused to have a large capacitance. Supercapacitors use this mechanism to store electrical energy. In general, the advantages of supercapacitors include high power density, short charge and discharge times, long loop life, wide operating temperature range, and so on.

However, due to current technical limitations, the operating voltage of a single supercapacitor is often limited, so in practice many supercapacitors are used in series. Most manufacturers now connect multiple supercapacitors in a soldered manner, but this approach suffers from the following problems:

(1) Since the temperature of the soldering process is high, the supercapacitor may be worn out.

1 is a front elevational view of a supercapacitor module 100 in accordance with a first embodiment of the present invention. Figure 2 is a cross-sectional view along line 2 of Figure 1. As shown in FIGS. 1 and 2, a super capacitor module 100 includes a first electrode 110, a second electrode 120, a first electrolyte 130, a third electrode 140, a fourth electrode 150, a second electrolyte 160, and a connection electrode 170. The encapsulation film 180. The second electrode 120 is disposed opposite to the first electrode 110. The first electrolyte 130 is interposed between the first electrode 110 and the second electrode 120. The fourth electrode 150 is disposed opposite to the third electrode 140, and between the second electrode 120 and the fourth electrode 150 There is a groove 175. The second electrolyte 160 is interposed between the third electrode 140 and the fourth electrode 150. The connecting electrode 170 is electrically connected to the first electrode 110 and the third electrode 140, and the first electrode 110, the connecting electrode 170 and the third electrode 140 form an integrally formed plate. The encapsulation film 180 encapsulates the first electrode 110, the second electrode 120, the first electrolyte 130, the third electrode 140, the fourth electrode 150, the second electrolyte 160, and the connection electrode 170, and at least a portion of the encapsulation film 180 protrudes into the trench In 175, the first electrolyte 130 and the second electrolyte 160 are sealed thereby.

Of course, each of the electrodes (for example, the first electrode 110, the second electrode 120, the third electrode 140, the fourth electrode 150, and the connection electrode 170) may be an activated carbon cloth or a mesh or plate in which fibers are combined with metal.

In the present embodiment, the combination of the first electrode 110, the second electrode 120 and the first electrolyte 130 can be regarded as one super capacitor, and the combination of the third electrode 140, the fourth electrode 150 and the second electrolyte 160 can be regarded as another Super capacitor. The two supercapacitors are electrically connected by the first electrode 110, the connecting electrode 170 and the third electrode 140, instead of being electrically connected by an additional soldering process, thereby solving the soldering process. The problem caused.
