Abstract

MATERIAL DE ELETRODO ATIVO. A invenção refere-se a materiais de eletrodo ativo e a métodos para a fabricação de materiais de eletrodo ativo. Tais materiais são de interesse como materiais de eletrodo ativo em baterias de íons de lítio ou íons de sódio. A invenção fornece um método para produzir um material de eletrodo ativo, sendo que o método compreende: fornecer um óxido de nióbio misto; combinar o óxido de nióbio misto com um precursor de carbono para formar um material intermediário, em que o precursor de carbono compreende carbono sp2 poliaromático e é selecionado de carbonos de piche, óxido de grafeno e misturas dos mesmos; e aquecer o material intermediário sob condições redutoras para pirólise do precursor de carbono formando um revestimento de carbono no óxido de nióbio misto e introduzindo vacâncias de oxigênio no óxido de nióbio misto, formando assim o material de eletrodo ativo.
