Progress of Recycling and Seperation of the Electrode Materials from Spent Lithium-ion Batteries

With the development of economy and electronic technology, Lithium-ion Batteries (LIBs) have become new flourishing energy-materials. With the wide utilization and consumption of them, there are large amounts of spent lithium-ion batteries produced. The LIBs contain many valued metals, and the recovery and utilization of them can not only reduce environmental pollution, but also slow the lack of resource effectively, increase social and economic benefit. These methods for recovery and separation of LIBs are introduced, and the existing problems and prospect of the recycling recovery technologies are put forward.
