Removal of phosphorus and fluorine from wastewater containing PF₆⁻via accelerated decomposition by Al³⁺ and chemical precipitation for hydrometallurgical recycling of lithium-ion batteries

Abstract

During hydrometallurgical recycling of lithium-ion batteries (LIBs), one important challenge is the efficient treatment of wastewater containing LiPF6 used as lithium salt in the LIBs. The difficulty of the treatment...
