How to reasonably recycle and dispose of scrapped power lithium batteries?Lithium battery pole sheet crushing and sorting production line

According to Shenzhen Shmu New Energy Technology shares: 2020 is an unusual year for the electric vehicle industry, because it will usher in the first peak of our national power battery recycling and scrapping.

New energy vehicles in 2014 began a large number of domestic popularity, we all know that the power battery life is about 8 years, according to statistics, in 2020 our national power battery cumulative retirement can reach about 200000 tons, in this year is expected to have 420000 tons of retired power lithium battery, the number will continue to double by 2025.

This brings about an important question, how to deal with these scrapped power lithium batteries?If not handled well, it will bring serious secondary pollution, so that the pursuit of environmental protection of new energy vehicles will become not environmentally friendly.Because for the five substances that threaten the natural environment, there are three batteries, such as lithium iron phosphate batteries, which can cause toxic corrosion.Inflow into the natural environment causes great pollution.And the commonly used ternary lithium battery it also has the manganese, cobalt, nickel these heavy metal will cause serious pollution to the water and soil.So what is the reasonable way to recycle these batteries?How do you use it?

At present, there are two ways to recycle lithium batteries, one is cascade utilization, the other is recycling.Cascade utilization is to detect classified disassembly and recombination.Reuse the good-condition whole packs, modules, and cells in other scenarios where the battery performance is less demanding.So recycling what we are doing is dry crushing, decomposition and refining, after tearing, crushing, positive and negative electrode powder screening, waste gas treatment and a series of processes to achieve the recycling and cost of battery material reduction.Many people would say that the recycling of lithium batteries is not environmentally friendly.We can do that the whole process from the battery breaking to the final refining is closed.Sealed conveyor belt carries broken battery waste.The treatment process is running in the negative pressure, the equipment is equipped with alkali water spray system, pulse dust removal system, air purification system, the whole set of treatment down, to ensure a good labor environment.Environmental-friendly recycling to scrapped lithium batteries inside the valuable metal substances.In addition, the recovery of waste lithium battery cathode plate, cathode plate in the copper foil, aluminum foil and black powder also has a good effect.
