Ternary battery recycling equipment

　　A lithium-ion battery primarily consists of a casing, positive and negative electrodes, an electrolyte, and a separator. The + element is constructed by coating lithium cobalt oxide powder on both sides of an aluminum foil current collector using PVDF as a bonding agent. The - element has a similar structure, consisting of carbon powder bonded to both sides of a copper foil current collector. Lithium-ion batteries offer significant advantages such as high voltage, high specific capacity, long life, and no memory effect. Since their commercialization, they have rapidly captured the market for powering portable electronic devices, with production increasing annually. With a service life of approximately two years, waste lithium batteries, if improperly handled, pose a potential environmental threat due to the lithium hexafluorophosphate, organic carbonate compounds, and heavy metals such as cobalt and copper they contain. On the other hand, the cobalt, lithium, copper, and plastics contained in waste lithium batteries are valuable resources with high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only offers significant environmental benefits but also offers significant economic benefits.
