A method and device for safely dismantling and recycling lithium-ion batteries

Abstract

The invention discloses a lithium-ion battery safe dismantling recovery method and its device, which belong to the field of lithium-ion power battery recovery. The inert gas in the tank is passed into the body through the trachea as a protective gas; Step 2: Put the lithium-ion battery into the body through the waste battery inlet, so that the waste battery falls smoothly on the transport mechanism for transportation; Step 3: The waste battery passes through the transport mechanism Transport to the fixing mechanism to cut the waste battery; step 4: slide the cut waste battery to the separation mechanism through the conveying plate, so that the shell and core of the waste battery are separated; step 5: make the separated shell fall into the shell box for collection, so that the core slides through the blanking plate into the core box for collection. The invention can effectively ensure the stability of the waste battery during disassembly, and avoid the phenomenon that the high temperature generated at the cutting position ignites the battery material and causes fire.

Description

technical field [0001] The invention relates to the field of recycling lithium-ion power batteries, in particular to a highly automated lithium-ion battery safe dismantling and recycling method and a device thereof. Background technique [0002] Nowadays, with the consumption of ore energy, various countries are actively developing new energy drives, and my country is no exception. In recent years, my country has also begun to actively develop new energy vehicles, and the power source medium used in new energy vehicles is lithium ion. However, lithium-ion batteries need to be replaced with new lithium-ion batteries after being used for a period of time, and the scrapped and used lithium-ion batteries will pollute the environment, so the disposal of used lithium-ion batteries has baffled many enterprises. my country's power battery recycling industry is still in its infancy. Although there has been some research on automatic battery dismantling equipment, due to the different ...

AI Technical Summary

Problems solved by technology

Because the waste power battery still has a certain amount of energy, and there are flammable components such as electrolyte in it, so when dismantling, the high temperature generated at the cutting position will cause the local temperature to reach the ignition point of some materials in the battery. There will be a fire phenomenon, and at the same time, most of the existing automatic dismantling equipment is not efficient in dismantling. A safe and intelligent dismantling technology for lithium-ion batteries with different shapes for recycling lithium-ion batteries is necessary
