Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, the present utility model provides a technical solution: an aluminum nail for a new energy battery, including a top cover 1, the top cover 1 is composed of a cylinder and a frustum located below the cylinder. An annular groove 2 is provided on the top surface of the top cover 1 near the edge position, a positioning groove 3 is provided at the center position of the top surface of the top cover 1, a clamping groove 4 is provided on the bottom surface of the top cover 1, and the top cover 1 is made of aluminum material;

[0021] By using the top cover 1 made of aluminum material, not only can its own flexibility be ensured, but also it is convenient to stamp the annular groove 2, the positioning groove 3 and the clamping groove 4 in one time. And the stamped top cover 1 can make its outer wall matte under mold processing, so that it is convenient for the top cover 1 not to generate reverse laser during laser welding, so as to facilitate its more firm welding. Then, through tools, it can be pressed on the annular groove 2, so that the clamping groove 4 on the top cover 1 can be stably pressed into the positive electrode material of the battery, so that it can be tightly combined with the top cover 1 and the positive electrode material. At this time, the top cover 1 can not only help maintain the structural stability of the positive electrode material and extend the service life of the battery, but also prevent electrolyte leakage, so as to improve the safe use of the new energy battery. Through the positioning groove 3, it is convenient to fix the external temperature sensor, so that the temperature sensor can monitor the temperature change of the battery during operation to ensure that the battery operates within a safe temperature range.

[0022] Refer to Figure 1 , Figure 3 , the positioning groove 3 is in a depth conical shape, which is convenient for installing and fixing the temperature sensor.

[0023] Refer to Figure 3 , the top diameter of the top cover 1 is 15.6 ± 0.05 mm, the bottom diameter of the top cover 1 is 14.46 ± 0.1 mm, and the height of the top cover 1 is 1.9 ± 0.05 mm, which is convenient for the forming of the aluminum nail and can save materials.

[0025] Refer to Figure 3 , the distance from the top surface of the top cover 1 to the top surface of the inner cavity of the clamping groove 4 is 1 ± 0.05 mm, which can ensure the thickness at the center of the top cover 1 and further improve the structural strength of the top cover 1.

[0026] During operation, the top cover 1 made of aluminum material can not only ensure its own flexibility, but also facilitate the stamping of an annular groove 2, a positioning groove 3 and a clamping groove 4 in one step. Moreover, the outer wall of the stamped top cover 1 can be made matte under mold processing, which can facilitate the top cover 1 to avoid anti-laser during laser welding, making the welding more secure. Then, by using a tool, it can be pressed on the annular groove 2, enabling the clamping groove 4 on the top cover 1 to be stably pressed into the positive electrode material of the battery, thus closely combining the top cover 1 with the positive electrode material. At this time, the top cover 1 can not only help maintain the structural stability of the positive electrode material and extend the service life of the battery, but also prevent electrolyte leakage, thereby improving the safety of new energy battery use. Through the positioning groove 3, it is convenient to fix an external temperature sensor, enabling the temperature sensor to monitor the temperature change of the battery during operation to ensure that the battery operates within a safe temperature range.
