Abstract

Se proporcionan procesos para formar silicio microporoso útil como un material activo en un electrodo de una celda electroquímica, los procesos incluyen someter una mezcla de óxido de silicio y un agente reductor de metal, opcionalmente aluminio, fresar mecánicamente para formar óxido de silicio/aluminio activado mecánicamente, tratar térmicamente el óxido de silicio/aluminio para reducir el óxido de silicio y formar Si/Al2O3 y remover al menos una porción de la alúmina del Si para formar un silicio microporoso. El silicio microporoso electroquímicamente activo resultante también está provisto con alúmina residual presente en un 15% en peso o menos que demuestra ciclo de vida y seguridad excelentes.
