电动飞机作为航空业减排的一种有前途的方法，已经获得了吸引力。这一转变将需要克服与提高电池能量密度相关的众多技术挑战，以及与锂供应链相关的物流挑战，由于对电动汽车的高需求，锂供应链已经受到压力。我们估计，电动航空对锂的需求可能会使锂需求增加10- 250%。这些估计的不确定性表明量化电气化航空的影响和设计电池以缓解额外需求的重要性。此外，大多数关于电气化航空的评论都没有包括锂需求造成的局部社会和环境影响的信息，尽管它们对实现减排所需的技术至关重要。本文旨在通过对环境和社会研究的概述来填补这一空白，以鼓励该领域的研究人员将这些动态视为电气化飞机设计的一部分。鉴于实现飞机大规模电气化所需的高能量密度电池仍在开发中，该领域的持续进展应强调锂提取的可持续治理和循环电池经济，以减少社会和环境压力。
Electrified aircraft have gained traction as a promising approach to emissions abatement in the aviation sector. This transition will require overcoming numerous technical challenges related to increasing battery energy density, as well as logistic challenges related to the lithium supply chain, which is already stressed due to high demand for electric vehicles. We have estimated that lithium demand for electrified aviation may raise lithium demand in the range of 10–250%. The uncertainty in these estimates show the importance of quantifying the impacts of electrified aviation and designing batteries to mitigate additional demand. In addition, most reviews on electrified aviation do not include information on the localized social and environmental impacts caused by lithium demand, despite their importance to enabling technology necessary for emissions reductions. This review seeks to fill this gap by presenting an overview of environmental and social research in context with one another to encourage researchers in the field to consider these dynamics as part of electrified aircraft design. Given that the high energy density batteries necessary to enable large-scale electrification of aircraft are still under development, continued progress in this field should emphasize sustainable governance for lithium extraction and a circular battery economy to reduce social and environmental stressors.
