Abstract
a presente invenção refere-se a um novo processo para a preparação de partículas isotrópicas de compósito carbonáceo com propriedades cristalográficas, morfológicas e mecânicas favoráveis, em que partículas carbonáceas primárias relativamente finas são revestidas com um material precursor aglutinante carbonáceo, aglomerado e finalmente tratadas com calor em temperaturas dentre cerca de 1850 e 3500°c para converter o material precursor aglutinante em carbono grafítico ou não grafítico, dessa forma, resultando em materiais compósitos carbonáceos isotrópicos altamente estáveis em que as partículas primárias do agregado são mantidas juntas pelo aglutinante carbonizado/grafitado. a presente revelação também se refere às partículas isotrópicas de compósito carbonáceo obtenível pelo processo descrito aqui. a descrição se refere ainda aos usos do dito material compósito carbonáceo isotrópico em várias aplicações, incluindo como material ativo em eletrodos negativos em baterias de íon de lítio e em produtos secundários, contendo o dito material compósito carbonáceo isotrópico.
