[0030] Here’s how it works:

[0031] When the high-power supercapacitor with a full-ear horn structure is to be used, it is necessary to assemble it in advance. First, the two negative electrode pins 132 and the foil guide strip 133 provided inside the ear structure 13 are respectively provided at the upper and lower ends of the insulating cover plate 131, and the upper and lower negative electrode pins 132 and the foil guide strip 133 are connected to each other. In this way, the two negative electrode pins 132 and the foil guide strip 133 can be arranged along the outer side of the insulating cover plate 131 to form a full-ear horn structure state;

[0032] After completing the assembly of the tab structure 13, the lower ends of the foil strips 133 on both sides need to be riveted to the rivet points 125 provided on both sides of the upper end of the collector sheet 124 inside the winding core 12, so as to achieve the docking of the foil strips 133 and the negative pole tab 122 provided at the upper end of the winding core body 121, and ensure the subsequent high-power conductive coordination, thereby completing the combined docking of the winding core 12 and the tab structure 13;

[0033] Next, the winding core body 121 can be placed as a whole inside the aluminum shell 111, and the positive pole column 126 provided at the middle of the lower end of the positive pole ear 123 can make the positive pole column 126 and the mounting hole 112 opened at the lower end of the aluminum shell 111 be accurately connected in advance, and correspondingly welded to complete the firm combination of the winding core 12 and the shell 11. At this time, the insulating cover plate 131 will be located at the unclosed opening at the upper end of the aluminum shell 111, so that the upper end of the aluminum shell 111 will be rolled and reinforced by an external rolling device, so that the aluminum shell 111 can be firmly assembled. The upper end of the aluminum shell 111 is rolled inwardly to form a roll opening 113, so that the roll opening 113 can wrap the outer side of the insulating cover plate 131 to perform the clamping and fixing of the insulating cover plate 131, so that the entire pole ear structure 13 is in a stable installation state. Finally, a roller groove 114 is formed on the outer side of the upper end of the extruded aluminum shell 111 to stably combine and dock with the external bracket, so that multiple supercapacitor bodies 1 can be stably stacked and placed. In this way, the assembly of the high-power supercapacitor with a full-pole ear horn structure can be completed;

[0034] The negative electrode pin 132 and the foil guide strip 133 in the full-ear horn structure can assist in improving the charging or power generation power when the winding core body 121 cooperates with the negative electrode ear 122, the positive electrode ear 123 and the collector sheet 124 to perform charging or discharging activities, thereby efficiently meeting the charging and discharging requirements;

[0036] The utility model provides a high-power supercapacitor with a full-pole-ear horn structure, which can achieve a firm sealing fit by setting a shell 11, with the cooperation of a roll-up opening 113 set at the upper end of an aluminum shell 111, to ensure that the supercapacitor main body 1 is firmly assembled, and a winding core main body 121 is set, namely, the winding core main body 121, the negative pole ear 122, the positive pole ear 123, the collector sheet 124 and the positive pole column 126, which can form a stable charging and discharging state, with high quality, high safety and long service life effects, and a pole ear structure 13 is set, namely, a negative pole pin 132 and a foil guide strip 133 can be combined along the upper and lower ends of an insulating cover plate 131 to form a full-pole-ear horn structure, to improve the overall charging and discharging power, adapt to most processes and equipment, have high versatility, and achieve the advantages of low-cost improvement and high-power charging and discharging.
