Synthesis of carbon/silicon composites |
摘要 |
The present embodiment relates to a method for preparing a composite graphite-silicon negative electrode material whereby an essentially dry mixture of graphite carbon powder and an element or elements selected from the new IUPAC Group Number 12-15 of the Periodic Table of Elements that can form alloys or compounds with lithium is prepared to provide an electrochemically active mixture. A mechanical agitation process serves to mix the constituent materials and to produce a fine dispersion with intimate contact between graphite and the Group 12-15 materials. A lithium ion battery negative electrode of this composition takes synergistic advantage of the high lithium capacity of some IUPAC Group materials and the long cycle-life of graphite negative electrode materials.
