Abstract

a presente invenção se refere a um novo material carbonáceo particulado com modificação da superfície que possui um revestimento de carbono não grafítico hidrofílico. o material pode, por exemplo, ser produzido pelo revestimento por cvd de um material carbonáceo particulado tal como grafite seguido por um tratamento oxidativo sob condições definidas. o material resultante exibe uma superfície mais hidrofílica em comparação a um material de carbono revestido por cvd não modificado, que é desejável em várias aplicações, tal como quando usado como um material ativo no eletrodo negativo de baterias de íon de lítio de ou em um material de compósito polimérico.
