Abstract: A method is provided for the manufacture of an electrode for a metal-ion battery. The method comprises sintering porous silicon-containing particles at a temperature of 500 to 1200°C and in an oxygen-free atmosphere to obtain particles of reduced BET surface area which are suitable for use as the active material of a metal ion battery when disposed onto a current collector.
