[0002] As electronic devices continue to evolve towards miniaturization and higher performance, the optimization of capacitors, as key components in electronic circuits, is crucial. While traditional capacitor core structures have undergone structural and material optimizations to improve efficiency and stability, they still face some challenges in practical applications.
[0003] Traditional capacitor core-pack structures often have tortuous ion conduction paths, resulting in low ion conduction efficiency. Under mechanical vibration or impact, the electrode and electrolyte layers inside the capacitor are prone to displacement or damage, leading to unstable capacitor performance. Therefore, we propose a new capacitor core-pack structure. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 A capacitor core package structure includes an insulating substrate 1, an anode electrode layer 2 fixedly connected to the upper surface of the insulating substrate 1, an anode lead terminal 3 fixedly connected to one side surface of the anode electrode layer 2, a solid electrolyte layer 4 fixedly connected to the upper surface of the anode electrode layer 2, an ion conduction channel 5 formed on the inner surface of the solid electrolyte layer 4, a cathode electrode layer 6 fixedly connected to the upper surface of the solid electrolyte layer 4, a protrusion 7 fixedly connected to the lower surface of the cathode electrode layer 6, a cathode lead terminal 8 fixedly connected to one side surface of the cathode electrode layer 6, a buffer layer 9 fixedly connected to the lower surface of the insulating substrate 1, an encapsulation frame 10 fixedly connected to the outer surface of the buffer layer 9, an inner encapsulation layer 11 fixedly connected to the outer surface of the encapsulation frame 10, an outer protective layer 12 fixedly connected to the outer surface of the inner encapsulation layer 11, and a heat dissipation fin 13 fixedly connected to the upper surface of the outer protective layer 12.
[0023] In this embodiment, the surface of the anode electrode layer 2 is chemically etched to form an uneven structure. The anode electrode layer 2 is fixedly connected to the packaging frame 10. With the anode electrode layer 2, the uneven structure formed by the chemical etching process greatly increases the contact area between the anode electrode layer 2 and the solid electrolyte layer 4, accelerates the ion conduction speed, and improves the charging and discharging efficiency of the capacitor.
[0024] Furthermore, multiple sets of ion conduction channels 5 are arrayed on the inner surface of the solid electrolyte layer 4. The ion conduction channels 5 are semi-circular in shape. By setting up the ion conduction channels 5, multiple sets of ion conduction channels 5 are arrayed on the inner surface of the solid electrolyte layer 4 during use, providing multiple parallel conduction paths for ions, which greatly increases the flux of ion conduction. The inner wall of the semi-circular ion conduction channel 5 is smooth and the curvature changes continuously, which can reduce the collision and scattering of ions during the conduction process, provide a smoother migration path for ions, reduce the resistance of ion conduction, and thus further improve the ion conduction efficiency.
[0025] Furthermore, the buffer layer 9 is set as a flexible insulating material, and the ion conduction channel 5 is set through the thickness direction of the solid electrolyte layer 4. With the setting of the buffer layer 9, in the actual working scenario of the capacitor, it is easy to be subjected to external mechanical vibration, impact and other forces, which may cause structural deformation and damage, thereby affecting the performance and stability of the capacitor. The buffer layer 9 can effectively absorb and disperse these forces, protect the key internal structure of the capacitor, and ensure that the capacitor can work stably in complex working environments.
[0026] In addition, the bumps 7 are arranged in an array on the lower surface of the cathode electrode layer 6. The height and density of the bumps 7 are set according to the performance requirements of the capacitor. By setting the bumps 7, when in use, the bumps 7 are arranged in an array on the lower surface of the cathode electrode layer 6, which increases the contact area between the cathode electrode layer 6 and the solid electrolyte layer 4, improves the efficiency of charge transfer, accelerates the charging and discharging speed of the capacitor, and improves the overall performance of the capacitor.
[0027] In addition, the outer surfaces of the anode lead-out terminal 3 and the cathode lead-out terminal 8 are treated with anti-oxidation, and the inner encapsulation layer 11 is set as an insulating material with good sealing performance. With the setting of the anode lead-out terminal 3 and the cathode lead-out terminal 8, when in use, the anti-oxidation treatment on the surface of the anode lead-out terminal 3 and the cathode lead-out terminal 8 can form a protective film on the terminal surface, preventing oxygen, moisture and other substances from contacting the metal, thereby effectively preventing the occurrence of oxidation reaction, making the conductivity and stability of the anode lead-out terminal 3 and the cathode lead-out terminal 8 better.
[0028] It is worth noting that the heat dissipation fins 13 and the outer protective layer 12 are integrally formed. Multiple sets of heat dissipation fins 13 are equally spaced on the upper surface of the outer protective layer 12. Through the arrangement of heat dissipation fins 13 and outer protective layer 12, the integral design of heat dissipation fins 13 and outer protective layer 12 can greatly improve heat conduction efficiency during use. Multiple sets of equally spaced heat dissipation fins 13 increase the heat dissipation area and improve heat dissipation efficiency.
[0029] During use, when the capacitor is connected to the circuit and begins charging, the external power supply drives electrons to flow from the anode terminal 3 out of the anode electrode layer 2, making the anode electrode layer 2 positively charged. Simultaneously, ions in the anode electrode layer 2 migrate towards the solid electrolyte layer 4. Under the influence of the electric field, the ions in the solid electrolyte layer 4 move towards the cathode electrode layer 6, while electrons flow through the external circuit to the cathode terminal 8 and accumulate on the cathode electrode layer 6, making it negatively charged, thus completing charge storage. During discharge, electrons in the cathode electrode layer 6 flow through the external circuit back to the anode electrode layer 2, while ions in the solid electrolyte layer 4 migrate in the opposite direction, releasing the stored charge. The anode electrode layer 2 is chemically etched to form a textured structure, increasing the contact area with the solid electrolyte layer 4 and improving ion exchange efficiency. It is fixedly connected to the packaging frame 10, enhancing structural stability. The ion conduction channels 5 within the solid electrolyte layer 4 are arranged in an array, and the semi-circular design reduces ion collisions. The structure features a through-hole design that shortens the migration distance and improves ion conduction efficiency. The buffer layer 9 is made of flexible insulating material, which can absorb and disperse mechanical stress and protect the internal structure. The array of protrusions 7 below the cathode electrode layer 6 increases the contact area with the solid electrolyte layer 4. The anode lead-out terminal 3 and cathode lead-out terminal 8 are treated with anti-oxidation to prevent oxidation from increasing resistance and ensuring reliable connection with external circuits. The heat dissipation fins 13 are integrally formed with the outer protective layer 12, reducing thermal resistance and improving heat conduction efficiency. Multiple sets of heat dissipation fins 13 with equal spacing increase the heat dissipation area, form convection channels, and reduce the capacitor's operating temperature. The inner encapsulation layer 11 uses insulating material with good sealing performance to block external moisture, dust, and chemicals, protect key internal components, and ensure stable capacitor performance. Through the optimized design and coordinated operation of each component, this structure significantly improves the capacitor's charging and discharging efficiency, stability, and service life, meeting the application requirements in complex environments.
