Abstract
The invention provides a positioning pressure-relief explosion-proof device of a soft package battery, belongs to the technical field of lithium battery safety devices, and solves the problem that anexisting battery cell is inflated and cannot release pressure is solved. The positioning pressure-relief explosion-proof device of the soft package battery comprises an explosion-proof shell and an explosion-proof chip, the explosion-proof device body is provided with a top seal clamping groove into which a cell top seal is inserted, the explosion-proof chip is provided with a tip positioned at one side of the top seal clamping groove, the explosion-proof shell is provided with an overturning groove, and the overturning groove is used for outwards overturning the explosion-proof shell, so thatthe tip is exposed and punctures a cell top seal area. The positioning pressure-relief explosion-proof device has the advantages of good pressure relief effect and the like.
Description
technical field [0001] The invention belongs to the technical field of lithium battery safety devices, and in particular relates to a positioning pressure relief explosion-proof device for a soft pack battery. Background technique [0002] Due to the advantages of high energy density, high output voltage, long cycle life, and low environmental pollution, lithium-ion batteries have been widely used in small digital electronic products, and have broad application prospects in electric vehicles, aerospace and other fields. Large-scale and high-energy lithium-ion battery packs are an inevitable trend in the development of lithium-ion batteries, but they are also the main obstacles to the development of lithium-ion batteries, and safety issues are becoming increasingly prominent. [0003] After the battery is put into use, due to the way the customer uses it, the environment in which the battery is used, or the reasons for a single cell itself, individual cells will be inflated. ...
