lithium cobalt oxide recovery method from lithium ion batteries

摘要

abstract of the disclosure 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. ************************************ Translation of the Summary Patent Summary: "Method for the Recovery of Lithium Ion Batteries Lithium Ion ". It is a method of recovering lithium cobalt oxide from spent lithium ion batteries, wherein said method is more environmentally friendly than methods known in the art today. The method includes a foam flotation step using renewable and biodegradable solvents such as formally hydrated terpenes and terpenes. The method can also include a relitiation step to return the li: co ratio to about 1: 1 for use in second-life applications. 20051866v1
