摘　　要：为贯彻落实绿色发展理念,了解电动汽车锂电池全生命周期的环境风险,通过匹配某款电动汽车的使用需求,从锂电池的全生命周期评价角度,收集磷酸铁锂电池(LFP)、锰酸锂电池(LMO)、三元锂电池(NCM)的材料清单与能源消耗清单,运用simapro 9.0软件进行数据处理,得到三种锂电池在生命周期内资源消耗与环境影响两方面的效益指标,实现对其环境效益评价。评价结果表明:磷酸铁锂电池的非生物资源消耗最大,三元锂电池的化石能源消耗最大,全球变暖与酸化是锂离子电池整个生命周期较为主要的环境损害方式。In order to implement the concept of green development and understand the environmental risks in the whole life cycle of lithium battery of electric vehicle,the material list and energy consumption list of lithium iron phosphate battery(LFP),lithium manganate battery(LMO)and ternary lithium battery(NCM)are collected from the perspective of life cycle assessment of lithium battery by matching the demand of an electric vehicle.Simapro 9.0 software is used to process the benefit indexes of three kinds of lithium batteries from two aspects of resource consumption and environmental impact in the life cycle,so as to realize the environmental benefit evaluation of three kinds of lithium batteries.The evaluation results show that lithium iron phosphate battery consumes the largest amount of non-biological resources,and ternary lithium battery consumes the largest amount of fossil energy.Lithium-ion battery in the whole life cyele contributes to global warming and aciditication.
