Abstract

RESVESTIMENTO DE CARBOBO AMORFO DE PARTÍCULAS CARBONÁCEAS A PARTIR DE DISPERSÕES INCLUINDO COMPOSTOS ORGÂNICOS ANFIFÍLICOS. A presente divulgação refere-se a um processo para a preparação de partículas carbonáceas de superfície modificada, em que as referidas partículas carbonáceas são revestidas com uma camada de superfície de carbono amorfo por dispersão de material carbonáceo com um composto anfifílico, secagem por pulverização da dispersão e subsequente calcinação do material seco. A divulgação também se refere a partículas carbonáceas de superfície modificada revestida com carbono amorfo, o que pode por exemplo ser obtidos pelo processo da invenção. A presente divulgação refere-se adicionalmente ao uso das partículas carbonáceas de superfície modificada em uma variedade de aplicações técnicas, tais como seu uso como um material ativo para os eletrodos negativos de baterias de íon-lítio. A presente divulgação também se refere a uma escova de carbono ou um material compósito de polímero, e, em geral, composições que compreendem as referidas partículas carbonáceas de superfície modificada, opcionalmente em conjunto com outros materiais carbonáceos ou não-carbonáceos.
