摘　　要：本研究引入了国际上新兴的足迹家族概念,建立了基于生命周期评价法的锂离子电池材料足迹家族评价方法体系.在此方法框架内,分别计算3种锂离子电池:LiFePO_4/C、Li Fe_(0.98)Mn_(0.02)PO_4/C和FeF_3(H_2O)3/C的碳足迹、水足迹和生态足迹,综合比较分析他们的足迹大小,由此讨论其环境影响,总结出足迹类指标评价锂离子电池材料的方法,并评估其适用性.对3种锂离子电池进行的足迹家族分析,得到下列结果:在同样合成1 kg电池正极材料的前提下,LiFe_(0.98)Mn_(0.02)PO_4/C的碳、水、生态足迹数值均为最大(对应足迹值分别为13.020 kg CO_2eq、23.865 m^3、38.432 m^2a),产生的环境影响也最大;Fe F3(H2O)3/C的碳、水、生态足迹数值均为最小(对应足迹值分别为8.712 kg CO_2eq、16.308 m^3、26.317 m^2a),产生的环境影响也最小.In recent years,lithium-ion batteries as new products in the field of battery have been widely researched and used with its outstanding advantages. Faced with the growing environmental problems,without reducing its battery performance of the premise,to ensure its strict environmental friendliness has become an important issue. In this paper,based on the Life Cycle Assessment（ LCA） method,we built a framework to calculate the‘footprint family＇of Li-ion battery materials.Through the method,we calculated the values of carbon footprint,water footprint and ecological footprint of three lithium-ion batteries, which called LiFePO_4/ C,LiFe_（0.98）Mn_（0.02）PO_4/ C and FeF_3（ H_2O）_3/ C. We compared and analyzed their numerical size and environmental impact,summarized the evaluation method for lithium-ion batteries by footprint indicators and constructed the evaluation system. The results for three batteries ‘footprint family＇are as follows：（ 1） Under the same premise of combining 1 kg battery cathode materials,carbon,water and ecological footprint of the Li Fe_（0.98）Mn_（0.02）PO_4/ C battery is maximum and it has the greatest environmental impacts（ The corresponding footprint values are 13. 020 kg CO_2 eq,23. 865 m3,and 38. 432 m^2·a）;（ 2） The FeF_3（ H_2O）_3/ C battery is just the opposite（ The corresponding footprint values are 8.712 kg CO_2 eq,16.308 m^3,26.317 m^2·a）.
