| abstract |
The present invention relates to a silicon / graphite / carbon composite (Si / G / C composite) comprising graphite (G) and non-agglomerated nano-sized silicon particles (Si), said silicon particles being embedded in an amorphous carbon matrix (C) Silicon / graphite / carbon composites. The invention also relates to a process for the preparation of a composite of this type, to an electrode material for a lithium ion battery containing such a composite, and to a lithium ion battery. |
