Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In this embodiment, refer to Figure 1 - Figure 5 The present invention relates to a novel high-current battery, comprising a battery cell 1 and a cap assembly. The cap assembly includes a main control circuit board 2, a positive electrode structure, and a metal cap 3. The metal cap 3 is mounted on the main control circuit board 2 via an insulating member 4. The main control circuit board 2 has an elastic structure 5 that penetrates the insulating member 4 and contacts the metal cap 3. The elastic structure 5 is specifically a spring.

[0025] Furthermore, the positive electrode structure includes a positive electrode cap 6 and a positive electrode ring 7. The positive electrode ring 7 is mounted on the upper end of the main control circuit board 2, and the positive electrode cap 6 is fitted onto the positive electrode ring 7. The upper and lower ends of the main control circuit board 2 are respectively provided with a positive electrode output section 8 and a positive electrode input section 9, which are connected to the positive electrode structure and the battery cell 1, respectively. The positive electrode cap 6 directly communicates with the main control circuit board 2 through the simple positive electrode ring 7, and the lower main control circuit board 2 directly connects to the battery cell 1 through the positive electrode input section 9. This significantly increases the contact area while greatly shortening the current transmission distance and reducing power loss. This ensures the current output efficiency of the battery cell 1, and the simple positive electrode ring 7 facilitates soldering and installation, resulting in greater stability. This allows the high-current battery of this invention to have excellent current output capability and stability, while ensuring battery safety. This design improves battery efficiency and provides users with a better user experience.

[0026] Furthermore, the positive electrode cap 6 is provided with an outwardly extending side circumference 601 in the middle. The lower end face of the side circumference 601 is connected to the upper end face of the positive electrode ring 7. The structure of the side circumference 601 effectively increases the contact area between the positive electrode cap 6 and the positive electrode ring 7, thereby further improving the stability of current transmission.

[0027] Furthermore, the lower end of the main control circuit board 2 is electrically connected to the battery cell 1 via a negative electrode ring 10. The positive electrode input section 9 is located in the middle of the negative electrode ring 10. The negative electrode ring 10 and the positive electrode input section 9 are arranged at intervals on the same layer, which not only saves space on the main control circuit board 2 but also makes the electrical connection between the negative electrode ring 10 and the battery cell 1 more stable. The design of the negative electrode ring 10 makes the current transmission smoother, reduces the generation of resistance, and further reduces power loss. At the same time, the interval arrangement of the negative electrode ring 10 and the positive electrode input section 9 on the same layer avoids mutual interference during current transmission and improves the battery's working efficiency.

[0028] Furthermore, the insulating component 4 is provided with a protective edge 401 surrounding the positive electrode structure. The protective edge 401 has an opening 402 for external communication. The lower end of the insulating component 4 has a locking position 403 for engaging with the main control circuit board 2. The design of the insulating component 4 not only ensures insulation between the positive electrode structure and the main control circuit board 2, but also effectively protects the positive electrode structure through the protective edge 401, preventing short circuits caused by external factors. Simultaneously, the opening 402 on the protective edge 401 allows current to be smoothly introduced into the positive electrode structure from the outside, ensuring normal battery operation. The locking position 403 at the lower end of the insulating component 4 allows it to be securely engaged with the main control circuit board 2, improving battery assembly efficiency and ensuring battery stability during use.

[0029] Furthermore, the electronic components of the main control circuit board 2 are located on the side away from the battery cell 1, which reduces the impact of heat generated by the electronic components on the main control circuit board 2 on the battery cell 1 and improves the service life of the battery cell 1. In addition, in the event of an accidental impact, the probability of contact between the electronic components and the battery cell 1 can be reduced, thereby reducing the probability of short circuits and improving the stability and safety of battery use.

[0030] Furthermore, it also includes a heat-shrink film 11 wrapped around the outside of the battery cell 1 and the cap assembly. The heat-shrink film 11 has good insulation and heat-sealing properties, which can effectively protect the battery cell 1 and the cap assembly and prevent external factors from damaging the battery. At the same time, the design of the heat-shrink film 11 can also improve the battery's sealing performance, prevent the leakage of moisture and gas inside the battery, thereby extending the battery's service life.

[0031] The metal cap 3 is designed in the shape of a cap, which effectively improves the stability of the installation by wrapping around the upper part of the main control circuit board 2. Alternatively, the metal cap 3 can also be designed as a sheet.

[0032] This invention optimizes the structural design of the cap assembly, particularly by having the metal cap 3 covered by an insulating component 4 on the main control circuit board 2 and an elastic structure 5 in contact with the metal cap 3. This design simplifies the battery assembly process, making it easier to produce batteries using automated equipment, thereby improving production efficiency. Simultaneously, this design reduces errors caused by manual assembly, improving battery quality and consistency.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
