چکیده
A watermelon-like internally inflated core-buffer-shell structural Si/electrochemically exfoliated graphene/C (Si/EG/C) composite is designed and prepared by the industrially established ball milling spray drying method. Owing to numerous folds voids in EG filled between nano silicon carbon shell, volume fluctuations of inside Si/EG/C particles are buffered lithium ions also could transport fast through channels. With these advantages, demonstrates excellent electrochemical performance. The anodes half cells exhibit no degradation initial capacity (834 mA h g−1) after 100 cycles. Moreover, Si/EG/C//LiCoO2 full retain almost 100% discharge 500 These results highlight potential applications next generation Li-ion batteries.
