In LIBs recycling, DESs are primarily used to leach valuable metals from the spent battery materials. The unique properties of DESs, including their ability to dissolve metal oxides, make them excellent candidates for extracting Li, Co, Ni, and other critical materials from the cathodes of spent batteries (details in section 3.1.1).
The ambitious plan of the EU aims to stimulate innovations in battery recycling and achieve a recycling rate of 70 % for LIBs by 2030 . Let's briefly explore the most common recycling methods for LIBs and their benefits and drawbacks. The first method is mechanical recycling, often considered as a pre-processing step [, , , ].
The first method is mechanical recycling, often considered as a pre-processing step [, , , ]. This method involves disassembling and shredding battery packs to separate the various components, followed by mechanical processing steps to recover valuable materials. LIB packs are disassembled to access the individual cells.
At present, there are some recycling methods for waste electrolyte, which fill the technical deficiencies to a certain extent and reduce the waste of resources . However, it is still necessary to accelerate the development of recycling technology for lithium-ion battery electrolyte.
Arenides used for battery capacity recovery must selectively act on the cathode, as shown in Figure 1 Biv, without degrading the inside of the battery, especially the graphite anode that reacts with the arenides leading to the destruction of the layered structure, 22 and for this purpose, control in the high-potential direction is important.
