Review analyzes life cycle assessment of next-gen batteries in electric vehicles, highlighting environmental impact variations.

To critically review life cycle assessment studies on next-generation secondary batteries for electric vehicles, focusing on methodologies and impacts.
Analyzed existing LCA studies of lithium-ion, all-solid-state, and lithium-sulfur batteries.
Examined definitions of goals and scopes in LCAs.
Compared life cycle inventories and environmental impact assessments across different battery technologies.
Identified higher environmental impacts of next-gen batteries due to energy-intensive manufacturing.
Noted inconsistent comparison across battery chemistries due to heterogeneous functional units.
Highlighted the need for standardized functional units for better comparative assessments.

Choi et al. (2025) studied this question.
