摘　　要：伴随着便携式电子产品的快速更迭和新能源动力汽车行业的迅猛发展,大量的锂离子电池迎来报废退役,其回收迫在眉睫。焙烧—水浸联合工艺不仅改进了传统火法熔炼工艺存在的高能耗、锂难以有效分离等问题,又解决了湿法回收工艺过程试剂耗量大、废水处理等缺点,将是失效锂离子电池正极材料有效处理回收工艺发展的未来趋势及前进方向。综述了当前联合工艺处理失效锂离子电池正极材料的研究进展,主要分为还原焙烧、盐化焙烧两大类,盐化焙烧工艺极大降低了所需焙烧温度,根据添加剂的不同可细分为硫酸化焙烧、氯化焙烧、硝化焙烧。通过对比分析不同联合工艺的优势和不足,总结展望联合工艺未来的发展趋势及前景,为未来研发更加清洁高效的回收工艺提供参考。With the rapid change of portable electronic products and the rapid development of the new energy power automobile industry,a large number of lithium-ion batteries ushered in retirement,the recycling is imminent.The combined process of roasting-water leaching improves the problems of high energy consumption and difficult effective separation of lithium in the traditional pyrometallurgical smelting process,also avoids the problems of large reagent consumption and wastewater treatment in the wet recovery process.It will be the future trend and direction of the development of effective treatment and recovery process for failed lithium-ion battery cathode materials.The research progress of current combined process for the treatment of failed lithium-ion battery cathode materials was reviewed.It is mainly divided into two categories:reduction roasting and salinization roasting.The salinization roasting process greatly reduces the required roasting temperature.According to the different additives,it can be subdivided into sulfation roasting,chlorination roasting and nitrification roasting.By comparing and analyzing the advantages and disadvantages of different combined processes,the future development trend and prospect of the combined process were summarized,which provides a reference for the future development of a cleaner and more efficient recovery process.
