Abstract

"MATERIAL ATIVO NEGATIVO PARA BATERIA SECUNDÁRIA DE LÍTIO E UM MÉTODO PARA PREPARO DO MESMO". São fornecidos, um material ativo de ânodo para uma bateria secundária de lítio tendo capacidade reversível elevada e excelente eficiência na carga/ descarga, compreendendo um complexo composto de partículas de fase de Si ultra-finas e um óxido circundando as partículas de fase de Si ultra-finas, e um material de carbono; e um método para preparar o mesmo. A presente invenção da mesma forma fornece um método para preparar um material ativo de ânodo para uma bateria secundária de lítio compreendendo produzir um complexo composto de partículas de Si ultra-finas e um óxido circundando as partículas de Si ultra-finas misturando-se um óxido de silício e um material tendo um valor absoluto de entalpia de formação de óxido (<30>H~ for~) maior do que aquele do óxido de silício e entalpia de formação óxido negativo por um processo mecanoquímico ou submetendo-o à uma reação termoquímica para reduzir o óxido de silício; e misturar o complexo de óxido contendo fase de Si e o material de carbono.
