Lithium battery positive paste leak-proof structure and leak-proof method thereof

Abstract

The invention discloses a lithium battery positive paste leak-proof structure. The structure comprises a battery body, a fixed plate and a conductor rod; a positive end of the battery body is fixedlyconnected with the fixed plate through a bolt, the middle part of one end, far away from the battery body, of the fixed plate is connected with a connecting pipe in hollow arrangement; a first fixingring and a second fixing ring are uniformly clamped at the external of the connecting pipe; the end part, close to the positive electrode, in the fixed plate is connected with a screwed joint, multiple damping springs are uniformly connected between the external of the screwed joint and the inner wall of the fixed plate; the end parts of the damping springs are connected with sleeved in the sleeving manner; one end of each sleeve is fixedly connected with an inner wall of the fixed plate. The positive end is more firm and hard to crack, the internal paste cannot leak, and the security performance is good. The stabilization performance is improved in the use, the positive electrode of the battery can be changed, the structure can be suitable for different demands in the use, and the conducting is uniform and stable. The positive end is hard to damage, and the battery can maintain good strength after falling off from the height or being impacted 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 duri...
