英文摘要	A facile and low-cost citrate-nitrate gel combustion route was conceived to synthesize micro/nanostructured SiOx/C composite. Auto combustion process generated ultrafine and chemically active SiO2 nanopowders with a loose and porous structure. A simple carbon coating process was continuously adopted to carbothermally reduce the O/Si atomic ratio of the combustion synthesized SiO2 precursor, and simultaneously create a carbon outer layer on secondary particles. The obtained SiOx/C composite has a micro-sized loose particle structure, composing of a great deal of primary nanoparticles. The micro/nanostructured SiOx/C composite exhibits a high and stable reversible capacity of ca. 740 mAh g(-1), and excellent good rate capability. The low O/Si atomic ratio, unique micro/nanostructure and sufficient carbon component ensure the excellent electrochemical performance of the combustion synthesized micro/nanostructured SiOx/C.
