How do we get Li from lithium battery recycling?

Lithium-ion battery is the best performance rechargeable battery in the world, it has the advantages of high working voltage, long cycle charging time, small self-discharge, no memory effect, low pollution and long service life. Therefore, it is widely used in communication equipment and new energy vehicles, such as: cell phones, tablet PCs, laptops, electric vehicles and new energy vehicles. Due to the massive use of lithium resources, the consumption of lithium, which is a non-renewable resource.

When the service life of these batteries is over, there are often resources that can be recycled in the discarded old batteries, which protects lithium resources. Therefore, the recycling of waste batteries in a variety of effective resources, easing the resource constraints at the same time and to achieve sustainable development.

Commonly used recycling methods are: (1) chemical recycling method - the use of chemical solvents  (2) Physical recycling method - through lithium battery recycling equipment recycling

The use of chemical solvents to recover used lithium batteries, not only need to soak the battery for a long time, will reduce the recovery efficiency, and at the same time will produce a large number of polluted gases, these gases can not be dealt with in a timely manner. Chemical treatment process separation is complex, the conditions are more difficult to control, high cost.

Lithium battery recycling equipment is physical treatment of all kinds of waste batteries, a wide range of applications, a device can handle a variety of types of batteries, such as: cylindrical batteries, soft pack batteries, hard shell batteries and so on. The workflow of the first lithium battery recycling equipment is first shredding, drying, then sorting out the diaphragm, separating iron and nickel strips through magnetic separation, and finally grinding, separating copper and aluminum through specific gravity sorting. This recycling method is highly efficient, highly automated, and the purity of the separated metals is high. And the waste gas generated in the process of shredding and sorting will be treated and then discharged through the supporting environmental protection equipment. Maximum resource recovery and environmental protection at the same time, to achieve the "green" recycling of waste batteries.
