Life Cycle Assessment of Nanotechnology in Batteries for Electric Vehicles
Book Contribution - Chapter
Through the usage of life cycle assessment methods, two different battery systems are benchmarked. One is composed by traditional Li-ion NMC graphite cells and the other, Li-ion NMC silicon nanowire ones. Their characteristics are displayed and challenged throughout different impact categories, such as climate change, human toxicity, and cumulative energy demand. These impact categories highlight the damages provoked during manufacturing, usage, and recycling of the battery systems within an electric vehicle usage scenario. Results show that silicon nanowire systems have slightly more impacts in climate change and cumulative energy demand categories, while regarding human toxicity, NMC graphite-based cells display higher scores.
