The present invention relates to novel electroactive materials comprising graphite carbon phase C and (semi) metal phases and / or (semimetal) oxide phases (MO x phase), as well as anodes for lithium-ion batteries of such electroactive materials It relates to the use of. The invention also relates to a process for the preparation of such materials. Electroactive materials include a) C on carbon; And b) one or more MO x phases, where M represents a metal or semimetal, x represents a number greater than 0 and less than k / 2, and k represents the maximum valency of said metal or semimetal. In the electroactive material according to the invention the carbon phases C and MO x phases form essentially co-continuous phase regions, the maximum average distance between two adjacent regions of the same phase being 10 nm, in particular 5 nm, even more particularly 2 nm to be. |
