Problems solved by technology
[0003] However, in the manufacturing process of lithium-ion batteries, some impurities (such as metal dust and molten metal beads) will inevitably be splashed when the components of the battery (such as tabs and collector plates) are assembled and welded. Inside the battery, the presence of impurities will bring certain safety hazards to lithium-ion batteries in daily use

The invention discloses a battery center pin and a battery. The battery center pin comprises a body and an adhesive part, wherein the body comprises a first end part and a second end part which are oppositely arranged; a hollow cavity is formed in the body in the axial direction of the body and penetrates through the first end to form a first opening. The adhesive piece is connected to the first end and covers the first opening, and the side, away from the hollow cavity, of the adhesive piece is sticky. As the adhesive piece in the battery center pin has certain viscosity, after the battery center pin disclosed by the invention is placed in a battery shell, metal impurities splashed in the assembling and welding operation of the battery can be adsorbed through the adhesive piece at the end part of the battery center pin, and the probability that the battery is damaged during daily use of the battery is reduced. And therefore, the safety performance of the battery is improved.
Description
technical field [0001] The present application relates to the field of batteries, and more particularly, to a center pin of a battery and a battery. Background technique [0002] With the gradual popularization of the concept of green environmental protection, new energy vehicles have become a hot research direction at present. Therefore, the importance of lithium-ion batteries as the power source of new energy vehicles has become increasingly prominent. The manufacturing equipment and manufacturing process of lithium-ion batteries are mature, and they have the advantages of low cost, strong reliability, and good consistency, so they are widely used in the new energy vehicle market. [0003] However, in the manufacturing process of lithium-ion batteries, some impurities (eg, metal dust, metal beads) will inevitably splash during assembly and welding operations on battery components (eg, tabs, current collectors) Inside the battery, the existence of impurities will bring cer...
