Abstract

The invention discloses an anti-leakage structure for the positive electrode slurry of a lithium battery, which comprises a battery body, a fixing plate and a conductor rod. The connection pipe is hollow, and the outside of the connection pipe is evenly clamped and installed with a first fixed ring and a second fixed ring. The inside of the fixed plate is connected with a threaded joint near the end of the positive electrode, and several damping springs are evenly connected between the outside of the threaded joint and the inner wall of the fixed plate, and the end of the damping spring is sleeved and connected with a sleeve. One end is fixedly connected to the inner wall of the fixed plate. The positive end is firmer and less likely to break, the slurry inside will not leak, and the safety performance is good. The stability in use is improved, the length of the positive electrode of the battery can be changed to meet different needs in use, and the conduction is uniform and stable. The positive end is not easy to be damaged, and the battery can maintain good strength after falling from a high place or being hit by other objects.

Description

technical field [0001] The invention relates to a leak-proof structure, in particular to a leak-proof structure and a leak-proof method for a positive electrode slurry of a lithium battery, belonging to the field of lithium battery manufacturing and application. Background technique [0002] With the continuous development of electronic products, the volume of internal batteries is getting smaller and smaller, and lithium batteries are commonly used as batteries for electronic products. Lithium batteries are small in size, strong in power storage capacity, and have a wide range of applications. However, the slurry inside the lithium battery is easy to leak during use, and the two extremes are prone to damage. [0003] The existing anti-leakage structure of the positive electrode slurry of lithium batteries still has certain deficiencies in use. The existing anti-leakage structure of the positive electrode slurry of the lithium battery has poor protection performance during...
