Description

Technical Field

[0001] The utility model belongs to the technical field of tab copper strips, and in particular relates to a lithium battery tab copper strip with high stability. Background Art

[0002] Copper strip is a metal component with product specifications of 0.1~3×50~250mm in various states. It is mainly used to produce electrical components, lamp holders, battery caps, buttons, seals, connectors, and is mainly used as conductive, heat-conductive, and corrosion-resistant equipment, such as electrical components, switches, washers, gaskets, vacuum devices, radiators, conductive base materials, and various parts such as automotive water tanks, heat sinks, and cylinder plates.

[0003] The tab is an important component in lithium-ion batteries. It connects the positive and negative electrodes of the battery cell, ensuring that current can flow smoothly into and out of the battery, thereby realizing the battery's charge and discharge functions. It is the external manifestation of the chemical reaction inside the battery and is a key part of the battery's energy conversion. The tab is a metal conductor that leads the positive and negative electrodes out of the battery cell. In layman's terms, the "ears" of the positive and negative poles of the battery are the contact points during charging and discharging. The lithium battery tab copper strip is mainly used to make the negative electrode tab;

[0004] The structure of the common lithium battery tab copper strip is relatively simple. Due to the properties of the copper strip itself, the welding performance during soldering is relatively poor. Problems such as falling off are prone to occur during the welding process, affecting the assembly quality of the battery and insufficient practicality. In addition, the copper strip has a low bending resistance and is prone to breakage during use, affecting the stability of battery use. Utility Model Content

[0005] The purpose of the utility model is to provide a lithium battery tab copper strip with high stability to solve the technical problems of poor solder joint performance and low bending resistance, so as to achieve the purpose of improving practicality and stability in use.

[0006] In order to solve the above technical problems, the utility model provides a lithium battery tab copper strip with high stability, comprising a copper strip body, with connecting components symmetrically installed at both ends of the copper strip body;

[0007] The top of the copper strip body is symmetrically provided with grooves near the left and right sides, and titanium metal strips are arranged inside the grooves;

[0008] The connecting component comprises a fixing block, a slot is opened and closed on the inner side of the fixing block, and fixing components are symmetrically installed on the top of the fixing block near the front and back sides, penetrating the slot and the copper belt body.

[0009] Furthermore, the outer surface of the copper strip body is treated with a galvanizing process.

[0010] Furthermore, the titanium metal strip is adapted to the groove and is connected by a welding process.

[0011] Furthermore, the fixing block is made of aluminum metal, and the periphery is nickel-plated.

[0012] Furthermore, several nickel metal strips are welded around the fixing block except for the inner side thereof near the bottom.

[0013] Furthermore, the fixing assembly includes a threaded rod, the threaded rod is threadedly connected to the fixing block, a sleeve is provided on the outer periphery of the threaded rod near one end of the bottom, and the threaded rod is threadedly connected to the sleeve.

[0014] Furthermore, a circular groove is formed at the bottom of the slot corresponding to the sleeve, and the sleeve is welded to the circular groove.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Example:

[0026] like Figures 1 to 3 As shown, a lithium battery tab copper strip with high stability includes a copper strip body 1, with connecting components 2 symmetrically installed at both ends of the copper strip body 1, grooves 101 symmetrically opened near the top of the copper strip body 1 on the left and right sides, and titanium metal strips 102 are arranged inside the grooves 101, and the connecting component 2 includes a fixing block 201, a slot 202 is opened and closed on the inner side of the fixing block 201, and fixing components 203 are symmetrically installed on the top of the fixing block 201 near the front and back sides, penetrating the slot 202 and the copper strip body 1, and the copper strip body 1 can be fixed to the fixing block 201 by the fixing component 203.

[0027] like Figures 1 to 3As shown, the outer surface of the copper strip body 1 is treated with a galvanizing process. Metal zinc has the advantages of good corrosion resistance, good electrical conductivity, and good antibacterial properties. The galvanizing process can enhance the corrosion resistance of the copper strip body 1 and improve its service life. The titanium metal strip 102 is adapted to the groove 101 and is connected by a welding process. Metal titanium has high strength, light weight, excellent corrosion resistance, good biocompatibility and unique physical and chemical properties. The titanium metal strip 102 can improve the bending resistance of the copper strip body 1, prevent the copper strip body 1 from breaking during use, and improve the stability of use. The fixing block 201 is made of aluminum metal and the outer periphery is treated with a nickel plating process. Nickel is a silvery-white metal with good ductility and corrosion resistance. It can remain stable in harsh environments, is insoluble in water, and has strong corrosion resistance to acids and alkalis, but is easily soluble in dilute nitric acid and aqua regia. In addition, metal nickel has good soldering properties, which can improve the soldering performance of the copper strip body 1 and prevent the copper strip body 1 from falling off during the welding process. , to improve practicality, the fixed block 201 is welded with several nickel metal strips 2011 around the inner side near the bottom. The nickel metal strips 2011 can increase the welding area, thereby further enhancing the welding stability of the fixed block 201 and improving practicality. The fixing component 203 includes a threaded rod 2031, which is threadedly connected to the fixed block 201. A sleeve 2032 is provided on the outer periphery of the threaded rod 2031 near the bottom end, and the threaded rod 2031 is threadedly connected to the sleeve 2032. By rotating the threaded rod 2031 so that it is immersed in the sleeve 2032, the copper strip body 1 can be fixed in the slot 202, so that the copper strip body 1 and the fixed block 201 are connected to prevent them from loosening and improve the stability of use. A circular groove 2021 is provided at the bottom of the slot 202 corresponding to the sleeve 2032, and the sleeve 2032 is welded to the circular groove 2021. By welding the sleeve 2032 and the circular groove 2021, the connection between the two can be tighter and more firm, thereby improving the stability of use.

[0028] To sum up, when assembling and using a lithium battery tab copper strip with high stability, first insert the copper strip body 1 into the slot 202, insert the threaded rod 2031 from the top of the fixed block 201 and pass through the copper strip body 1 and the slot 202, insert it into the sleeve 2032, rotate the threaded rod 2031 so that it spirals into the sleeve 2032 to complete the fixation of the copper strip body 1, and the titanium metal strip 102 can enhance the bending resistance of the copper strip body 1 to prevent the copper strip body 1 from breaking during use, greatly reducing the impact on the battery and effectively improving the stability of use. Finally, solder wire can be used to weld the fixed block 201 and the nickel metal strip 2011 to the external battery components to complete the entire assembly process. The nickel plating process of the fixed block 201 and the nickel metal strip 2011 can improve the soldering performance and prevent the copper strip body 1 from falling off during the welding process, greatly reducing the impact on the battery assembly quality and effectively improving the practicality.
