Abstract: A method of recovering lithium cobalt oxide from spent lithium ion batteries, wherein said method is more environmentally friendly than the methods presently known in the art. The method includes a froth flotation step using renewable and biodegradable solvents such as terpenes and formally hydrated terpenes. The method can also include a relithiation step to return the Li:Co ratio back to about 1:1 for use in second-life applications.

Abstract translation: 从废锂离子电池中回收钴酸锂的方法，其中所述方法比本领域目前已知的方法更环保。 该方法包括使用可再生和可生物降解的溶剂如萜烯和正式水合萜烯的泡沫浮选步骤。 该方法还可以包括将Li：Co比率返回到约1:1的重复步骤，以用于第二寿命应用中。
