Abstract

Recognized by the 2019 Nobel Prize in Chemistry, lithium-ion batteries (LIBs) have a growing demand in response to the increasing variety of their applications, such as: consumer electronics, stationary storage, large industrial applications and electric vehicles. The cathodic material of LIBs is formed mainly by an oxide containing lithium (Li) and some valuable metals such as cobalt (Co), nickel (Ni) and manganese (Mn) and others, less valuable, such as iron (Fe). The scarcity of natural resources and the search for more sustainable products and industrial processes impose challenges on the entire production and consumer chain of LIBs. Thus, the objective of this project is to develop a technology for recycling LIBs, aiming at its implementation on an industrial scale for the production and commercialization of the produced goods. In this scenario, recycling provides for the closure of the LIBs' life cycle, where those at the end of their lives undergo a process that is capable of efficiently recovering the most relevant materials for the market. After sorting, the recycling process will consist of the following steps: discharge, opening, separation of cathodic and anodic materials, and obtaining the metals of interest. Within each stage, the sub-processes will be carried out in a closed cycle in order to reinsert all by-products generated in the useful productive chain, aiming to increase the environmental and economic performance of this product in its productive and consumer chain, promoting its circular economy.
