Abstract

The synthesis, microstructure and electrochemical properties of ball milled Si85Fe15Ox alloys with different oxygen contents are investigated. These materials combine the features of Si-M alloys (low irreversible capacity) and SiOx materials (high thermal stability). This makes Si85Fe15Ox alloys compatible with high temperature processing. As shown here, these properties allow Si85Fe15Ox alloys to be incorporated into carbon-coated graphite composite particles that can cycle well even without the use of advanced binders or electrolyte additives.
