How to deal with scrap lithium batteries?

2021-05-07

Lithium-ion batteries (hereinafter referred to as lithium batteries) have significant advantages such as high voltage, large specific capacity, long life and no memory effect. Since their commercialization, they have quickly occupied the power source market for portable electronic and electrical equipment, and their output has increased year by year. Big. Lithium batteries are electronic consumables with a service life of about 2 years.

If discarded lithium batteries are improperly handled, the lithium hexafluorophosphate, carbonate organics, and heavy metals such as cobalt and copper will inevitably pose a potential pollution threat to the environment. On the other hand, cobalt, lithium, copper and plastics in waste lithium batteries are precious resources and have extremely high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits.

Lithium batteries are mainly composed of a shell, a positive electrode, a negative electrode, an electrolyte and a separator. The positive electrode is constructed by coating lithium cobalt oxide powder on both sides of the aluminum foil current collector through PVDF which has a binding effect; the negative electrode structure is similar to the positive electrode, and is composed of carbon powder bonded on both sides of the copper foil current collector. At present, researches on the recycling of waste lithium batteries are mainly focused on the recovery of valuable cathode precious metals cobalt and lithium, and there are few reports on the separation and recovery of anode materials. In order to alleviate the increasingly serious resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to realize full-component recycling of waste materials.

SUNY GROUP has launched a professional lithium battery separation and recycling equipment for crushed batteries. This machine can crush, disassemble, and separate various waste batteries, lithium batteries, electric vehicle batteries, and car batteries to achieve the purpose of recycling.
