近年來，新能源汽車的逐漸普及帶動了動力鋰離子電池數量的指數級增長，從而致使大量電池廢棄物產生，浪費資源的同時對環境產生潛在風險。因此，退役鋰離子電池的回收利用成為目前研究熱點之一。綜述了主要的退役鋰離子電池回收利用技術及其研究現狀。首先，介紹了鋰離子電池的分類及特征，討論了其回收的必要性與緊迫性。其次，總結了鋰離子電池預處理及分離方法，包括機械粉碎、磁選、篩分、化學溶解、熱處理等，著重分析了鋰離子電池正極材料的傳統回收利用技術，包括火法冶金、濕法浸出、材料再生等。最后，剖析了高效利用退役鋰離子電池的新技術，包括生物浸出技術、機械化學處理方法、電化學方法、超臨界流體技術以及微波/超聲波技術等。基于以上分析，總結和展望了退役鋰離子電池的回收和利用發展方向，為相關科研工作者和生產工作者提供借鑒。

Abstract:

In recent years, the gradual popularization of new energy vehicles has led to the exponential growth of power lithium-ion batteries. This results in a large amount of battery waste, which is both a waste of resources and a potential risk to the environment. Therefore, the recycling of spent lithium-ion batteries is one of the current research hotspots. This paper summarizes the main recycling technologies for spent lithium-ion batteries and their research status. Firstly, the classification and characteristics of lithium-ion batteries are introduced, and the necessity and urgency of their recycling are discussed.Secondly, the pretreatment and separation methods of lithium-ion batteries are summarized, including mechanical crushing, magnetic separation, screening, chemical dissolution, heat treatment, etc. In addition, the analysis of the traditional recycling technologies of lithium-ion batteries cathode materials are focused, including pyrometallurgy, hydrometallurgy, and materials regeneration. Finally, new technologies for the efficient utilization of spent lithium-ion batteries are dissected, including bioleaching technology,mechanochemical treatment, electrochemical methods, supercritical fluid technology, and microwave/ultrasonic technology. Based on the above analysis, the development direction of recycling and utilization of spent lithium-ion batteries is summarized and outlooked to provide reference for related researchers and production workers.
