Current status and research progress of recovery and recycling of electrolyte and anode materials of spent lithium-ion batteries
The research on the recovery of cathode materials from spent lithium-ion batteries was extensively studied. The current status of electrolyte and anode material recovery and utilization were reviewed. The pretreatment of spent LIBs was firstly reviewed. Then,the collection of electrolyte and the conversion and recovery method of lithium salt were discussede. Moreover,the research status of regenerated graphite by hydrometallurgy,pyrometallurgy and the combined process was summarized. Besides,research on the regeneration of anode materials into other functional materials such as graphene,adsorbents and catalysts was also reviewed. Finally,the challenges and opportunities for the recycling of anode materials were summarized,aiming to provide guidance for the recycling of electrolyte and anode materials of spent LIBs.
