제목 Semimicro-size Agglomerate Structured Silicon-Carbon Composite as an Anode Material for High Performance Lithium-Ion Batteries
초록 A semimicro-size agglomerate structured silicon-carbon (mSi-C) composite is constructed by an aggregation of silicon nanoparticles (~100 nm) coated with conductive carbon layer through a facile and scalable aerosol-assisted process to be employed as an anode material for lithium-ion batteries (LIBs). As-formed mSi-C composite delivers good electrochemical performances of high reversible capacity (2084 mAh/g) between 0.01-1.50 V (vs. Li/Li+) at 0.4 A/g, 96% capacity retention (1999 mAh/g) after 50 cycles and good rate capability (906 mAh/g) at 12 A/g. Such good performances can be attributed to unique composite structure which accommodates the stress induced by volume change of silicon during lithiation/delithiation.
