High capacity graphite-silicon composite anode material for lithium-ion batteries

▶ A new way to produce a graphite/silicon composite anode material. ▶ Gelatinous silicon compound is decomposed on a porous natural graphite. ▶ Silicon is not only on the graphite surface deposited, also in graphite pores. ▶ Stable cycling over 100 cycles at 840 mAh g−1, excellent efficiency of over 99%.
