Description

Technical Field

[0001] The present invention relates to the technical field of capacitors, and in particular to a supercapacitor monomer with a heat dissipation structure. Background Art

[0002] A supercapacitor cell is the basic unit of a supercapacitor. It is an electrochemical component that stores energy through a polarized electrolyte and is also known as an electrochemical capacitor. Supercapacitor cells primarily rely on a double layer and redox pseudocapacitive charge to store electrical energy. A double layer forms between the electrode and the electrolyte. During charging, randomly distributed ions in the electrolyte migrate toward the electrode surface of opposite polarity under the action of an electric field, thereby storing charge. No chemical reaction occurs during this process, and the energy storage process is reversible.

[0003] For example, application number: CN202210008037.3 provides a supercapacitor monomer that can dissipate heat efficiently, which relates to the field of supercapacitor technology, including a box, a heat sink, a heat dissipation component, and a shock-absorbing component. A plurality of air outlets are provided on one side of the box, and an air inlet is provided on the other side of the box. A filter is provided inside the air inlet, a heat sink is provided inside the box, a heat conduction plate is provided inside the heat sink, and a plurality of capacitor monomers are provided inside the heat sink. A heat dissipation component is provided between the box and the heat sink for dissipating heat from the heat sink. This type of supercapacitor achieves efficient heat dissipation of the supercapacitor through the coordinated use of fan blades, air inlets, heat conduction plates, air vents, and heat sinks, and achieves shock absorption through the coordinated use of spring columns and rubber pads.

[0004] When using existing supercapacitor cells, the sealing cover and the shell are usually connected and fixed by welding, glue sealing, etc. The assembly process is time-consuming and labor-intensive. If the installation position of the electrode, electrolyte or diaphragm needs to be temporarily adjusted, the sealing mechanism is easily damaged, resulting in material waste. Moreover, the heat dissipation function of the traditional shell for heat exchange is relatively simple, and the internal heat dissipation is not ideal, which affects the heat dissipation effect of the supercapacitor. In addition, during transportation, it is easily affected by vibration and external force. The internal core is affected by inertia, and collisions may cause internal short circuits or poor contact.
