Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

Flow diagram of the battery system, defined by the functional unit of 50 MJ stored and delivered to the powertrain. Researchers from the Norwegian University of Science and Technology (NTNU) have performed life cycle assessments (LCA) of three batteries for plug-in hybrid (PHEV) and full performance battery electric (BEV) vehicles.

Lifecycle study finds that environmental impacts of silicon-anode Li-ion battery could be roughly comparable with conventional Li-ion battery

Green Car Congress

The results showed that more than 50% of most characterized impacts are generated from the battery operations, while the battery anode with SiNW material contributes to around 15% of global warming potential and 10% of human toxicity potential. kWh battery system comprising 12 modules with each module containing 12 LIB prismatic cells.
