Abstract: Research status for the recycling and regeneration of spent Li-ion batteries are introduced,and the recovery methods are reviewed,including calcinations,direct recovery and hydrometallurgy. Techniqes for recycling and re-synthesis of LiCoO2 positive electrode materials from spent Li-ion batteries are systematically summarized. Merits and demerits in each preparation process are discussed,and the existing problems and prospects for the recovery of spent Li-ion batteries are proposed.
