During the recycling of waste lithium-ion batteries, people pay more attention to the recycling of valuable metals, but rarely involve the electrolyte collection and harmless treatment. In fact, when the battery is opened, many organic components will evaporate into the air, posing a serious threat to the environment and human health. Recycling the electrolyte is

In advanced batteries such as lithium-ion batteries (LIBs), the stability between the electrolyte and electrodes (and consequently the reversibility of the battery) must be achieved kinetically. Thus, trace amounts of electrolytes are sacrificially decomposed, and their solid products are deposited on the electrode surfaces, forming a protection against further decomposition. This protection

Considering the average effective lives and calendar lives of power batteries, the world is gradually ushering in the retirement peak of spent lithium-ion batteries (SLIBs). Without proper disposal, such a large number of SLIBs can be grievous waste of resources and serious pollution for the environment.
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.
Liu et al. invented a recycling device that disassembles spent LIBs after discharge treatment under the protection of inert gas, and then extracts the electrolyte with propylene carbonate (PC) or ethylene carbonate (EC) .
