[0002] A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. During charging and discharging, lithium ions repeatedly insert and extract between the positive and negative electrodes. When charging, lithium ions extract from the positive electrode material, pass through the electrolyte, and insert into the negative electrode; when discharging, lithium ions extract from the negative electrode, pass through the electrolyte, and return to the positive electrode. At the same time, electrons flow from the negative electrode to the positive electrode through the external circuit, thereby generating current.

[0003] Existing lithium battery positive terminals typically possess a certain mechanical strength, enabling them to withstand external forces during installation and use, and are not easily deformed or broken. However, their anti-static interference performance is poor, which means that electrostatic interference may cause some damage to the materials and structure of the lithium battery positive terminal, greatly reducing the lifespan of the lithium battery. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency electrostatic discharge anti-interference lithium battery positive electrode post, which aims to improve the problem of poor anti-static interference performance of existing lithium battery positive electrode posts, which leads to a significant reduction in the service life of lithium batteries.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the excellent electrostatic scattering ability of graphene can improve the overall antistatic performance of the positive electrode post body.

The polymer layer 5 is made of polyaniline, which can be tightly attached to the surface of the positive electrode post to form a continuous conductive channel, achieving effective release of static electricity. It also has a certain degree of toughness, thus improving the overall strength of the positive electrode post body 2. Through the cooperation between the carbon base layer 3, the metal plating layer 4, and the polymer layer 5, the overall antistatic performance of the positive electrode post body 2 is improved.
