Electric vehicles are seen as an important means of action to achieve global climate change goals, and then, rechargeable batteries play an essential role in the right deployment of low-carbon electric mobility . However, their environmental cost in terms of resource depletion, toxicity, end-of-life recovery, among others, is not negligible. In response to the need of energy storage for mobility, the battery industry is evolving rapidly with the emergence of new high-density energy technologies. Because of the massive volume of batteries that will be deployed, it is necessary to analyze their technological feasibility according to a lifecycle approach, to identify the environmental challenges of innovative technologies when they are at a low level of maturity. The objective is to integrate environmental performance criteria early in the development of these new generations of batteries. This work aims at supporting the actors involved in the technological research to incorporate the environmental dimension into their R&D&I activities. It will support a sustainable development of the post-lithium generations for electric mobility and contribute to the development of an environmentally virtuous value chain for future generation of batteries. Thus, according to a lifecycle perspective, three technologies (advanced lithium-ion, lithium-sulfur and all-solid-state) with different technological maturities are analyzed through a multi-criteria environmental assessment approach. The quantitative, semi-quantitative or qualitative methods applied respond to the support requirements of the upstream actors during the implementation of their R&D activities in the design of future generations of batteries for electric mobility. In order to determine their environmental performance improvement potential, these new technologies are compared to a reference technology for the first time to the best of our knowledge.
