摘要:

隨著以新能源汽車為代表的新能源產(chǎn)業(yè)迅速發(fā)展，大量退役動(dòng)力鋰離子電池隨著使用壽命終結(jié)而形成新興的“城市礦產(chǎn)”。因此，在“雙碳”背景下，如何高效、環(huán)保、低碳地實(shí)現(xiàn)鋰離子電池資源循環(huán)成為當(dāng)前研究的難點(diǎn)和熱點(diǎn)。綜述了正負(fù)極材料的再生方法和再生用途，目前，正負(fù)極材料的再生方法主要包括直接再生（固相法、水熱法、熔鹽焙燒法）和間接再生（共沉淀法、溶膠凝膠法），并分別概述它們?cè)诠�業(yè)生產(chǎn)應(yīng)用中的優(yōu)缺點(diǎn)；負(fù)極材料被修復(fù)再生后可應(yīng)用于正負(fù)極材料、催化劑、吸附劑、石墨衍生物和石墨聚合物材料的構(gòu)建，充分展現(xiàn)了資源的可持續(xù)循環(huán)利用。最后，分析廢舊鋰離子電池再生利用所面臨的困難與挑戰(zhàn)，并對(duì)廢舊鋰離子電池再生利用的工業(yè)實(shí)踐進(jìn)行展望，為實(shí)現(xiàn)鋰離子電池資源循環(huán)提供可行的參考意見。

Abstract:

With the rapid development of the new energy industry led by new energy vehicles, a large number of spent power lithium batteries have formed an emerging “urban mineral” with the end of their service life. Therefore, under the background of “dual-carbon”, how to realize the resource recycling of lithium-ion batteries in an efficient, environmentally friendly and low-carbon way has become the difficulty and hot spot of current research. At present, the regeneration methods of cathode and anode electrode materials mainly include direct regeneration (solid phase method, hydrothermal method, molten salt roasting method) and indirect regeneration (co-precipitation method, sol�瞘el method), and the advantages and disadvantages of their application in industrial production are summarized. After being repaired and regenerated,the negative electrode materials can be applied to positive and negative electrode materials, catalysts, adsorbents, graphite derivatives and graphite polymer materials, etc., fully demonstrates sustainable recycling of resources. Finally, it analyzes the difficulties and challenges faced by the recycling of used lithium-ion batteries and looks forward to the industrial practice of recycling used lithium-ion batteries, so as to provide feasible references for the realization of lithium-ion battery resource recycling.
