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