Abstract

"A ¡°mixed cathodes¡± LIB recycling process was first proposed and developed in the CR3 center at Worcester Polytechnic Institute. This process can efficiently and economically recover all the valuable metal elements in LIB waste. In the end of the recovery process, lithium, nickel, manganese, and cobalt ions will be recovered in the leaching solution. The objective of this work is to utilize the leaching solution to synthesis NixMnyCoz(OH)2 precursors and their corresponding LiNixMnyCozO2 cathode materials. The synthesized cathode materials can be used to build new LIBs, allowing the overall process to be a ¡°closed loop¡±. "
