Summary:A powder for use in a negative electrode of a battery, the powder comprising particles, the particles comprising a matrix material and silicon-based particles dispersed in said matrix material, the powder having a total specific volume of open porosity at least equal to 0.005 cm3/g and at most equal to 0.04 cm3/g, a total specific volume of closed porosity at least equal to 0.01 cm3/g and at most equal to 0.1 cm3/g, and a ratio of the total specific volume of open porosity over the total specific volume of closed porosity at least equal to 0.05 and at most equal to 0.95.
