Environment Impact Analysis of Natural Graphite Anode Material Production

Abstract:

A quantitative analysis on the environment impact of natural graphite anode material is carried out based on life cycle assessment (LCA) method in this paper. The results show that, the main environment impact categories are human toxicity potential, particulate matter formation potential and marine ecotoxicity potential, which account for 26%, 19% and 15% of total environment impacts, respectively. The processes of production, purification and surface modification cause the strongest impact on the environment, because they consume a large number of electricity. Under the current electricity structure of China, improving the production technology and reducing the energy consumptions of purification and surface modification, are the effective methods of environment impact reduction for LIB anode materials.
