Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 5 to Figure 9 A battery explosion-proof system shown mainly includes a sealing ring 4, a cap 5 and an anti-explosion ball 6 arranged in the cap 5. The present invention mainly aims at optimizing the design of the sealing ring 4 material and the cap 5. In the existing various The polypropylene material is selected to be made into the sealing ring 4 among the plastic materials. The polypropylene material will soften or partially melt under high temperature conditions of 80°C-100°C, causing a gap between the battery steel shell and the cap to release the gas inside the battery, reduce the internal pressure of the battery, and prevent the battery from exploding. In the design of the cap 5, rubber that can fail under high temperature conditions is selected as the material of the explosion-proof ball 6....

Abstract

The invention discloses a battery anti-explosion system, mainly aiming to optimally select the design of sealing ring materials and cover caps, and polypropylene materials are selected to manufacture sealing rings from the various traditional plastic materials. The polypropylene materials are softened or partially melted at the high temperature of 80-100 DEG C, a gap appears between the steel shell of a battery and the cover cap of the battery so as to release the inner gas of the battery, the inner pressure of the battery is reduced, and the explosion of the battery is prevented.

Description

technical field [0001] The invention relates to a battery explosion-proof system. Background technique [0002] With the rapid development of electronic digital products, the performance requirements for supporting battery products are constantly increasing. The existing market not only has requirements for conventional performance such as battery capacity and lifespan, but also pays more attention to the safety performance of the battery. The emergence of sealed batteries has greatly expanded the scope of use of batteries, but the safety performance of sealed batteries has always been the direction of battery manufacturers to improve. Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, at present, battery manufacturers use a nylon-66 sealing ring 1 and a common cap 2 to form an explosion-proof device for sealing the battery, and an explosion-proof ball 3 in the common cap 2 . Due to the high melting point of nylon-66 sealing ring 1, high rigidity and high st...
