交通，特别是私人交通，是污染排放的主要原因之一。为了减少这一问题，近年来电动汽车得到了大力发展，这也得益于许多国家实施的激励政策。尽管电动汽车代表了向脱碳迈出的重要一步，但它们仍然存在一些与电池生产和寿命终止相关的环境问题，因为它的扩散与电动汽车的扩散同步增长。在这种情况下，本研究代表了镍氢电池的第一个生命周期评估（LCA），它考虑了生产和回收过程。分析是通过比较电池生产产生的影响与回收技术相关的影响来进行的，考虑到不同的回收百分比。研究结果显示了电池报废回收对保护自然资源和人类毒性的好处。
Transport, and particularly private mobility, is one of the main causes of polluting emissions. In order to reduce this problem, electric mobility has been strongly developed in recent years, also thanks to incentive policies implemented by many Countries. Even if electric vehicles represent an important step towards decarbonization, they still present some environmental criticalities related to the production and end of life of batteries, since its diffusion grows hand in hand with that of electric vehicles. In this scenario the present research represents the first life cycle assessment (LCA) for nickel–metal hydride (NiMH) batteries, which considers production and recycling processes. The analysis was carried out by comparing the impacts deriving from the production of batteries with those associated with recycling technologies, taking into consideration different recycling percentages.The results show the benefits deriving from end-of-life recycling of batteries for the preservation of natural resources and human toxicity.
