Problems solved by technology

Although the device achieves a certain safety effect, the device cannot prevent combustion and explosion, and can only prevent the further expansion of combustion and explosion after it has already burned and exploded.
In particular, the poisonous gas produced by combustion and explosion cannot be stopped, and will continue to be produced, endangering the human body and the environment
In short, although this method can reduce the risk of failure of electrical components during a collision, this invention cannot solve the problem of combustion and explosion of power batteries.

Abstract

The invention discloses a method and device for storing and transporting a lithium ion battery. The method comprises the steps of placing the lithium ion battery in a closed container, wherein the closed container is provided with a door which can be opened and closed, and the closed container is provided with an exhaust pipe. The device is a closed container, and the closed container is providedwith a door capable of being opened and closed. Moreover, the closed container is provided with the exhaust pipe, a one-way valve is arranged on the exhaust pipe, an anti-backfire net is installed onthe exhaust pipe located behind the one-way valve, and an explosion-proof membrane is arranged on the closed container. According to the invention, the lithium ion battery can be effectively preventedfrom burning or exploding in the transporting or storing process, and the method and device have very important significance for personal safety and environmental protection.

Description

technical field [0001] The invention relates to a method and device for storing and transporting lithium-ion batteries, and belongs to the technical field of battery safety. Background technique [0002] Electric vehicles are developing rapidly. At present, the main power batteries of electric vehicles are lithium-ion batteries. The electrolyte in the current lithium-ion battery is a flammable and explosive material. When the lithium-ion battery is damaged or internally short-circuited, it will cause combustion and explosion, which leads to the storage and transportation of the current lithium-ion battery, especially the scrapped power battery. In the process of storage and transportation, combustion or explosion is prone to occur, causing personal injury and environmental protection accidents. For example, when a collision accident occurs during transportation, the positive and negative electrodes of the lithium-ion battery will generate sparks, which will ignite the electr...
