Abstract:

With rapidly growing on renewable energy vehicles,there presents a large amount of spent lithium-ion batteries including valuable lithium metals.Lithium recycles and utilizations from the spent batteries can reduce negative environment effect of solid-waste resources,and thus holding a significant contribution in the development for energy and environment applications.Currently,spent lithium-ion batteries comprise with various complex components.Meanwhile,resource recovery in lithium includes complex processes(dismantling,crushing,sorting,impurity removal,and element synthesis) with low efficiency.Thus,in order to realize efficient lithium recovery and their high-value utilizations,the research on recovery progress were summarized,involving traditional physical treatment,chemical treatment,and direct repair technology for emerging new electrodes.Furthermore,the key technology related to lithium extraction and the preparation in battery-grade lithium carbonate were reviewed,such as recrystallization,causticization,electrochemistry,and carbonation process.In addition,the prospects and challenges for further development of lithium recovery and battery-grade lithium carbonate were proposed.

Key words: spent lithium-ion power batteries, lithium recovery, lithium iron phosphate, ternary cathode materials, lithium carbonate
