摘要： A process for the preparation of a material comprising at least silicon particles and silicon nanowires, said process comprising: (1) introducing, into a chamber of a reactor, at least: silicon particles, and a catalyst, (2) introducing, into the chamber, a precursor composition comprising at least a silane compound or a mixture of silane compounds as precursor compound of the silicon nanowires, (3) decreasing the content of molecular oxygen in the chamber, (4) applying a heat treatment to the chamber at a temperature ranging from 270° C. to 600° C., and (5) recovering the material comprising at least silicon particles and silicon nanowires. A material based on silicon particles and on silicon nanowires and its use for manufacturing electrodes, notably anodes, which can be used in an energy storage device.
