Proper disposal of spent lithium-ion batteries is beneficial for the resource recycling and pollution elimination. Full liberation of electrode materials, including the liberation between electrode material and current collector (copper/aluminum foils) and the liberation among electrode material particles, is the pivotal precondition for improving the recovery efficiency of electrode materials. In this article, authors attempt to carry out a summary of current technologies used in the liberation of electrode materials derived from spent lithium-ion batteries. However, specialized studies about the liberation of electrode materials are insufficient at present. This research clearly shows that: (1) Organic binder must be removed so as to improve the liberation and metallurgy efficiency of electrode materials; (2) A collaboration of varied technologies is the necessary process to achieve high liberation efficiency between electrode materials and copper/aluminum foils; (3) Pyrolysis may be a recommended technology for removal of organic binder because part of pyrolysis products can be recovered. Finally, an alternative recycling flowchart of spent LIBs is proposed.

正确处理废旧锂离子电池有利于资源回收和消除污染。电极材料的充分释放，包括电极材料和集电器（铜/铝箔）之间的释放以及电极材料颗粒之间的释放，是提高电极材料回收效率的关键前提。在本文中，作者试图对用于释放废锂离子电池电极材料的当前技术进行总结。但是，目前关于释放电极材料的专门研究不足。这项研究清楚地表明：（1）必须除去有机粘结剂，以提高电极材料的释放和冶金效率；（2）要使电极材料与铜/铝箔之间具有较高的释放效率，必须进行各种技术合作。（3）热解可能是推荐的去除有机粘合剂的技术，因为可以回收部分热解产物。最后，提出了废旧LIB的替代回收流程图。
