'Green' technology put under scrutiny Tests uncover the environmental impact of electric vehicle batteries

摘要

Researchers in Norway are assessing the environmental impact of electric vehicle batteries during their life cycle in order to better inform car designers and policy makers. In their first study they found that nickel metal hydride (NiMH) batteries have a greater life cycle impact than iron phosphate Li-ion (LFP) or nickel cobalt manganese (NCM) Li-ion batteries. A shift to the latter should be encouraged, say the researchers, who caution that their work uncovered a greater impact for all three types than had previously been reported.
