Abstract

The invention discloses a lithium ion battery anti-explosion valve with reinforcing ribs. The anti-explosion valve comprises an anti-explosion valve ring, an anti-explosion valve cover and the reinforcing ribs, wherein the reinforcing ribs comprise the first reinforcing rib and the second reinforcing rib, the anti-explosion valve cover is fixedly connected with the inner side of the anti-explosion valve ring, an annular groove in a shape identical to the shape of the anti-explosion valve ring is formed in the anti-explosion valve cover, the first reinforcing rib and the second reinforcing rib are arranged in the middle of the anti-explosion valve cover and both fixedly connected to the top of the anti-explosion valve cover, and the opening of the first reinforcing rib and the opening of the second reinforcing rib face opposite directions. According to the lithium ion battery anti-explosion valve with the reinforcing ribs, the first reinforcing rib and the second reinforcing rib are formed in the mode of extrusion or drawing from the anti-explosion valve cover, the anti-explosion valve can be avoided from being deformed and broken in the transportation process, the problems that in a breath testing experiment, the anti-explosion valve is excessive in amplitude and accordingly is tore, and the anti-explosion value is excessively decreased can be avoided, the risk that the anti-explosion valve is deformed and broken in the production process is avoided, and the service life of the anti-explosion valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of explosion-proof valves for lithium-ion batteries, in particular to an explosion-proof valve for lithium-ion batteries with reinforcing ribs. Background technique [0002] The simplest lithium-ion battery top cover includes: top cover sheet, positive pole, negative pole, the negative pole and the top cover are insulated with plastic, there is a vent in the middle of the top cover, and the explosion-proof sheet is a very shallow pressure India, its disadvantages are: [0003] a The transportation process is easy to cause damage and deformation to the explosion-proof valve. [0004] b It is easy to break the explosion-proof valve in the breath test. [0005] c During the production process, the explosion-proof valve is prone to rupture and deformation when employees touch it. Contents of the invention [0006] The object of the present invention is to provide a lithium-ion battery explosion-proof valve ...
