摘要
我国的新能源电动汽车产业快速增长,在汽车使用过程带来碳减排收益的同时,动力电池的生产过程必然也会产生大量的碳排放。利用阿贡国家实验室提出的全生命周期估算方法,对电动汽车动力电池在3种不同流转场景下的碳排放情况进行估算,阐明最佳的电动汽车碳排放路径为动力电池再生利用与梯次利用相结合的综合利用路径。在理想情况下,综合利用路径相比汽车报废后电池直接无害填埋的方式,每千克动力电池可获得4.652 kg CO_(2)eq的降碳收益。通过敏感性分析,提出电动汽车产业在综合利用路径下的具体降碳策略,明确梯次利用应优先于再生利用,梯次利用过程应着重提高动力电池性能检测的准确率,综合利用企业应设置在电动汽车聚集地与动力电池工厂之间,三者间物流转运总路程不超过3 869 km。
The rapid growth of China's new energy electric vehicle(EV)industry has brought about carbon emission reduction benefits during the use of vehicles,while the production process of power batteries inevitably brings about a large amount of carbon emissions.Using the whole life cycle estimation method proposed by Argonne National Laboratory,the carbon emissions of electric vehicle power batteries in three different flow scenarios are estimated,and the best carbon emission path for electric vehicles is a comprehensive utilization path combining power battery recycling and secondary utilization.In an ideal situation,the integrated utilization pathway can achieve a carbon reduction benefit of 4.652 kg CO2eq per kg of power battery compared to the direct harmless landfill of batteries after vehicle end-of-life.Through sensitivity analysis,specific carbon reduction strategies for the electric vehicle industry under the integrated utilization path are proposed,specifying that secondary utilization should take precedence over recycling,that the secondary utilization process should focus on improving the accuracy of power battery performance testing,and that integrated utilization enterprises should be located between electric vehicle aggregation sites and power battery factories or no more than 1,800 km away from each other.
