Abstract

A critical issue that has dominated the field of Lithium-ion Batteries (LIBs) and Battery Electric Vehicles (BEVs) is their usefulness to climate change, their second life, and their recyclability. With recent developments in the discipline of circular economy, Life Cycle Assessment (LCA) of LIBs becomes important. There are numerous studies on LCA of LIBs and this paper investigates the existing LCA results to quantify the different parameters that could affect the decisions of a battery pack design engineer. Global Warming Potential (GWP) and Abiotic Depletion Potential (ADP) are the two most discussed environmental impacts among the previously executed LCA studies. GWP gives information on the carbon footprint associated with the usage of LIB whereas the ADP is associated with the depletion of resources, both environmental factors important to consider for a sustainable design process. This study also takes into account the Cumulative Energy Demand (CED) component, which provides a designer with a sense of the amount of energy used over the course of a LIB's lifetime. The authors of this work suggest a design process model for a LIB pack design based on these considerations, which aids a design engineer in making the right choices. Consequently, this helps the designer to achieve more utility of raw materials, making sparing use of resources and find potentials to reduce waste in different life stages of a LIB pack.
