The present invention relates to the use, as an electrode active material, of a particulate material comprising spherical silicon oxycarbide (SiOC) particles, said SiOC particles having an average particle size ranging from 0.1 to 100 µm; a sphericity ranging from 0.95 to 1.0; and a total content in carbon (C), silicon (Si) and oxygen (O) equal or greater than 98 wt%, with Si ranging from 20 to 50 wt%, C from 10 to 50 wt% and O from 20 to 50 wt%, and to a method for producing said particulate material. It also relates to an electrode active material, an electrode and a battery, especially a lithium-ion battery, including the aforementioned particulate material. |
