Research on Resource Recycling and Reuse of Battery Negative Electrode Materials

Abstract

With the continuous increase in demand for lithium batteries in the market, the number of discarded lithium-ion batteries (LiBs) is also rapidly rising. Recycling and reusing these eliminated negative electrode materials can effectively alleviate the environmental impact of waste LiBs and reduce resource waste. This paper focuses on the reaction mechanism of commonly used negative electrode materials in LiBs, summarizes the latest scientific research achievements in the recycling and reuse of negative electrode materials from waste LiBs, and explores the specific application conditions of different recycling technologies. At the same time, this paper also summarizes the application pathways of LiBs negative electrode materials in multiple industries, points out the technical difficulties and challenges encountered in the process of negative electrode material recycling, and predicts the future trends of negative electrode material recycling and regeneration.
