Silicon/Graphite/Amorphous Carbon as Anode Materials for Lithium Secondary Batteries.

ABSTRACT: Although silicon is being researched as one of the most promising anode materials for future generation lithium-ion batteries owing to its greater theoretical capacity (3579 mAh g^-1), its practical applicability is hampered by its worse rate properties and poor cycle performance. Herein, a silicon/graphite/amorphous carbon (Si/G/C) anode composite material has been successfully prepared by a facile spray-drying method followed by heating treatment, exhibiting excellent electrochemical performance compared with silicon/amorphous carbon (Si/C) in lithium-ion batteries. At 0.1 A g^-1, the Si/G/C sample exhibits a high initial discharge capacity of 1886 mAh g^-1, with a high initial coulombic efficiency of 90.18%, the composite can still deliver a high initial ch
