Abstract
The invention relates to methods for producing Si/C composite particles, characterised in that mixtures containing silicon particles, one or more oxygen-free polymers, one or more carbon additives based on a carbon modification and one or more liquid dispersing agents are dried by spray drying and the pre-composite particles thus obtained are thermally treated.
