Despite the success of the current Lithium-ion (Li-ion) cells, various next-generation cells are now being researched to overcome their performance and sustainability limitations. Focused on Electric Vehicles (EVs), this study aims to assess the environmental sustainability of several alternatives to current Li-ion cells. Chosen on the basis of their suitability to meet the performance and safety requirements for future EVs, the promising next-generation cells under study are two silicon-anode cells (i.e., Si-CPAN, SiNWs), an All-Solid-State cell (ASS) and a Lithium-Sulfur cell (Li-S). First, this study investigates the environmental impacts of the next-generation cells under study through a Life Cycle Assessment (LCA) approach.
