27 - Recovery of critical raw materials from battery industry process and wastewaters

Abstract

Critical raw materials (CRMs) are important for technological advancements. These CRMs such as cobalt, vanadium, lithium, and rare earth elements (La, Ce, Pr, and Nd) are significant elements of battery industries. Due to the rising cost of CRMs and limited primary resources, recovery of CRMs from secondary sources like spent batteries is gaining immense research interest. Owing to the critical role of CRMs in the battery industries, technological advancement in CRMs recovery from battery recycling wastewater is on a constant rise. Challenges associated with the recovery of CRMs from battery wastewater need to be tackled smartly. Recovery of CRMs from battery industry wastewater is considered, with the main focus on lithium-ion and NiMH batteries. Here, the characteristics of battery wastewaters are discussed, followed by key challenges and opportunities related to wastewater treatment. This chapter will provide an overview of recent advances in CRMs recovery approach from battery industry wastewater.
