Current status of battery recycling and technology

Abstract

In recent years, battery recycling has become one of the hot environmental issues in China. This paper analysis the current situation of battery recycling and the methods of recycling, and analyzes the effective means of recycling batteries under the existing conditions. The results show that the current situation of battery recycling in China is worrying, with no complete recycling industry chain and low recycling efficiency. And as the demand for batteries increases and the price of metals rises, the urgency of battery recycling is further increased. From the analysis of existing methods, pyrometallurgy is defective in many aspects and the environmental life cycle is not complete. The cost of electrolytic recycling method, although high recovery efficiency and wide range, requires adequate technology and high cost. Bioleaching method is highly efficient, low cost and produces almost no pollution. Although the technology is not mature enough and is still in the laboratory stage, the bioleaching method has a good future. This paper looks forward to exploring more appropriate recycling methods to address the current situation of battery recycling difficules in China and discusses the future prospects of these methods.
