Abstract

"MéTODO DE PREPARAçãO DE UM COMPOSTO DE INTERCALAçãO DE GRAFITA, E GRAFITA INTERCALADA". Um método de preparação de compostos de intercalação de grafita, no qual as partículas de grafita são imersas em um meio de eletrólito aquoso, que compreende um ácido e um agente de oxidação. As partículas de grafita imersas são submetidas a uma corrente anódica e, então, removidas do eletrólito e lavadas com um solvente. O excesso de solvente e o eletrólito, então, são removidos das partículas de grafita. As partículas de grafita podem ser colocadas em um tambor de eletrodeposição, o qual é imerso no eletrólito e girado, enquanto as partículas de grafita são submetidas à corrente. A grafita intercalada resultante tem um volume de expansão entre cerca de 100 ml/g e 2000 ml/g, quando aquecida até 1000 <198>C.
