A novel silicon/graphite material prepared by a new process, in which a gelatinous silicon precursor is deposited on porous natural graphite, is introduced. The obtained composite material provides an excellent cycling stability, high coulombic efficiencies and a good rate capability. Morphology and structure of the new material were examined by SEM/TEM measurements using focused ion beam technique for sample preparation.
