Abstract

Electric vehicles are gaining increasing room in the global market, since they are seen amongst the most promising solutions to cope with the growing concerns related to climate change and environmental pollution. The successful evolution of the transportation sector towards electro-mobility depends on the battery chemistry and technology, and its environmental impacts. However, the poor availability of data at the commercial production scale and the diversity in modelling choices make evaluating the environmental impacts of Lithium-ion batteries (LIB) difficult and uncertain. We aim at contributing to the creation of flexible and transparent life cycle inventories (LCI) of LIB for background databases by means of a consequently modular approach that will be applicable in the future as common framework to model new generations of LIB. In the present paper, we focus on (i) compiling modular LCI datasets of current and near-future market LIB chemistries, namely NMC111, NMC811 and NCA, by using the most recent data from existing sources, and (ii) exemplarily assessing the environmental impacts of the three modelled chemistries. This assessment takes into consideration a wide range of impact categories, with a focus on climate change and the comparison with the available literature in the sector. The whole is complemented with several sensitivity analyses, which show the relevance of transparency when making choices in compiling the LCI.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
