- Circularidade e Sustentabilidade na Utilização de Baterias de Veículos Elétricos em Fim de Vida: Uma Revisão BibliográficaPublication . Carlos, Simão André Maltez de Sá; Neves, Ângela Sofia Leal; Ferreira, Hugo Heitor Moreira EnesWith the expansion of electric mobility as an urgent response to the climate crisis, there is also growing concern about what to do with electric vehicle batteries at the end of their useful life. These batteries, which are essential for the operation of cars, contain valuable materials, but also pose environmental risks if disposed of improperly, making their sustainable management both a challenge and an opportunity. One of the most promising possibilities is to give batteries a “second life.” Even after they lose their optimal capacity for use in vehicles, they can be reused, for example, in stationary energy systems, as backup for homes or to support renewable energy sources. When reuse is not possible,recycling emerges as an indispensable alternative to recover valuable metals, such as lithium and cobalt, and reduce dependence on new extractions of these minerals. However, barriers still remain, such as the lack of standardization in battery design, limited recycling networks, and high costs that hinder the implementation of these solutions on a large scale. To overcome these challenges, a collective effort is essential, combining technological advances, effective public policies, and economic incentives. The goal is to transform electric vehicle batteries into a concrete example of a circular economy, where the end of one cycle represents the beginning of another. This path not only reduces environmental impacts but also opens up new opportunities for innovation and sustainability on a global scale. Thus, the life cycle and end of life of electric vehicle batteries will be critically analyzed, identifying reuse and recycling strategies that promote the circular economy, reduce environmental risks, and optimize the use of critical raw materials. For this, the methodology adopted is based on a systematic literature review, using scientific databases such as Web of Science and Google Scholar, with the definition of research questions and keywords that relate critical raw materials, emissions, and environmental impacts to battery reuse and recycling solutions. This dissertation concludes that the circularity of electric vehicle batteries is feasible when the sequence “reuse and then recycle” is prioritized, combining reliable diagnosis, design for disassembly, adequate logistics, and a regulatory framework to reduce environmental impacts, reinforce the security of critical raw materials, and support sustainable electric mobility.
