technical field

The invention relates to the field of lithium ion batteries, in particular to a dismantling device for waste lithium ion battery modules.

Background technique

With the emergence of environmental and energy issues, people's demand for electric vehicles is increasing, and power lithium-ion batteries, as the energy source of electric vehicles, are also increasing in demand. In order to meet market demand, battery manufacturers continue to expand production capacity, and new companies continue to produce lithium-ion batteries. The lifespan of lithium-ion battery vehicles is generally 5-8 years, so there will be a large number of waste lithium-ion batteries in the future. It is estimated that by 2020, the cumulative amount of lithium-ion batteries scrapped will be 120,000 to 170,000 tons. Although lithium-ion batteries do not contain mercury, lead and other toxic heavy metal elements, lithium-ion batteries, as discarded electrical and electronic products, have been designated as hazardous waste by each country. If not handled properly, it can cause a series of harm to the environment and human health. Moreover, lithium-ion batteries also contain precious and scarce metals such as cobalt, nickel, lithium, etc. Therefore, reasonable recycling of used lithium-ion batteries not only reduces pollution, but also saves energy.

The energy source of electric vehicles is the power battery pack, which generally consists of dozens to hundreds of battery modules, and the battery module is composed of several to dozens of single batteries. Therefore, regardless of the voltage, volume, energy or weight of used lithium-ion battery packs, they should not be underestimated, and there is a danger in dismantling them. At present, the disassembly of modules is generally carried out manually, which is inefficient, labor-intensive, and poses a threat to the personal safety of operators.
