【摘要】：废旧动力电池包中含有丰富的镍、钴、稀土等稀贵金属,其资源化利用是实现混合动力汽车(Hybrid Electrical Vehicle,简称HEV)全生命周期绿色化管理的重要内容之一。随着HEV的不断发展,动力电池包在未来几年将逐渐进入批量报废阶段,其资源化利用的环境效益成为值得关注的问题。鉴于此,以丰田混合动力汽车镍氢电池包为研究对象,利用GREET模型和LIME值法测算出,相比于原生矿开采,单位废旧镍氢电池包中稀贵金属资源化利用所产生的环境效益为1083元;根据报废周期,对我国市场上现存的HEV镍氢电池包的未来报废情况进行预测。结果表明,这些电池包将从2018年开始迎来报废,在2021年达到报废高峰,至2024年基本完成报废;预计其稀贵金属资源化利用的环境效益,可累计达9421万元。提出了加强废旧动力电池回收体系和资源化利用体系建设的政策建议。
[Abstract]:The waste battery pack contains rich rare and precious metals, such as nickel, cobalt, rare earth and so on. Its resource utilization is to realize hybrid Electrical Vehicle of hybrid electric vehicle. With the continuous development of HEV, the power battery package will gradually enter the phase of batch scrapping in the next few years. In view of this, taking the nickel hydrogen battery pack of Toyota hybrid vehicle as the research object, the GREET model and the LIME value method are used to calculate the environmental benefits of the utility model. Compared with the primary mining, the environmental benefit of rare and precious metals in the waste Ni-MH battery pack is 1083 yuan. According to the scrap cycle, the future scrap of the existing HEV Ni-MH battery packs in our country is forecasted. The results show that these batteries will be scrapped from 2018. Reached the peak of scrapping in 2021, and basically finished scrapping by 2024; It is estimated that the environmental benefit of the utilization of rare and precious metals can reach 94.21 million yuan. Some policy suggestions are put forward to strengthen the recovery system of waste power battery and the construction of resource utilization system.
