Abstract

The embodiment of the invention provides an anti-explosion valve protection patch, a battery top cover and a battery, and relates to the technical field of batteries. The explosion-proof valve protection patch, the battery top cover and the battery comprise a patch body made of a material which is separated from an electrolyte, a plurality of through holes are formed in the patch body, the aperture of each through hole is 0.01-100 microns, the aperture of each through hole is limited within the range of 0.01-100 microns, and the aperture is larger than that of a conventional waterproof breathable film, so that the explosion-proof valve protection patch can be breathable and can also block the electrolyte, and the explosion-proof valve protection patch can be prevented from being damaged. On the other hand, water and other substances which do not affect the performance of the explosion-proof valve are not blocked, and meanwhile the effects of water permeation, air permeation and electrolyte blocking are achieved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an explosion-proof valve protection sticker, a battery top cover and a battery. Background technique [0002] Batteries contain chemicals that create a large mixture of gases and liquids during charging and discharging, along with a constant build-up of pressure. If these pressures are not balanced or released in time, the lighter case will deform and leak, and the battery will explode if it is more serious. At present, most battery packs adopt a fully enclosed assembly process, and the application of explosion-proof valves can quickly ventilate and relieve pressure, prevent explosions, and solve the problem of self-explosion of new energy vehicle batteries. [0003] Existing secondary batteries are used to protect the explosion-proof valve, and the contact surface between the protective patch and the top cover is usually fixed above it, and grooves are made around the upper e...
