Claim 0:
1. A composite, which is a Si—O—C—Li composite comprising nano-silicon, a silicon-oxygen-lithium compound selected from the group consisting of Li2SiO3, Li4SiO4, Li2Si2O5, Li2Si3O7 and combinations thereof, silicon oxide and a carbon coating,
wherein the silicon-oxygen-lithium compound is partially crystalline, the nano-silicon is dispersed in the silicon-oxygen-lithium compound to form fusion particles of the nano-silicon and the silicon-oxygen-lithium compound without clear interface between the nano-silicon and the silicon-oxygen-lithium compound, and the fusion particles are uniformly dispersed in the silicon oxide to form a composite particle wherein all directions of the fusion particles are surrounded by the silicon oxide matrix, forming a sea-island structure with the fusion particles as islands and with the silicon oxide as the sea, with the carbon coating coated on the surface of the composite particles;
wherein the nano-silicon and the silicon-oxygen-lithium compound are produced by in-situ redox growth.
