Estudo de desempenho dos materiais mais promissores aplicados em ânodos de baterias elétricas veiculares considerando seu potencial de produção no Brasil
Abstract
The global energy context has undergone significant transformations in recent decades, driven
by the search for cleaner and more sustainable energy sources. In this sense, electric vehicles
have emerged as a promising alternative to reduce dependence on fossil fuels and mitigate
the environmental impacts caused by greenhouse gas emissions. However, the efficiency and
capacity of the batteries used in these vehicles are critical aspects for the viability of this
technology.
Brazil, with its wealth in natural resources, has considerable potential for the production of
materials used in electric batteries. Among these materials, graphite, silicon and niobium stand
out due to their unique properties and characteristics. Graphite is widely used as an anode in
lithium-ion batteries, while silicon and niobium are studied as alternatives to increase energy
storage capacity and improve battery performance.
In short, the work presented a comprehensive analysis on the production of electric batteries
with graphite, silicon and niobium anodes in Brazil, considering the context of mineral reserves
and the political scenario of the country, as well as the performance of these materials in
batteries. The results indicate a promising potential for the advancement of the electric mobility
industry in Brazil, provided that adequate policies and investments in research and
development are implemented.
