| 英文摘要 | Silicon (Si) is the most promising anode material for new generation high-performance Lithium-ion batteries (LIBs), but the colossal volume expansion and poor conductivity limit its applications. In this work, we develop a mussel-pearl-inspired Si-embedded carbon/graphite composite (Si/C composite) via a two-step process of ball-milling and subsequent annealing to overcome these obstacles. With this method, Si nanoparticles (Si NPs) are successfully embedded into dual-carbon structure with efficient protection like pearls in mussel. The Si/C composite as anode material shows an ultrastable reversible capacity of 670 mAh g(-1) with a superior Initial Coulombic Efficiency (ICE) of 89.4% and an ultrahigh capacity retention of 85% over 850 cycles. Besides, the prepared materials show superior rate capacity at the current density of 5 degrees C. The superior electrochemical performances can be attributed to the excellent structure stability of mussel pearl structure during cycling, which provides effective protection for Si NPs and accommodate the volume expansion. These results prove that a rational structure design for Si/C composite can present excellent electrochemical performances through a simple and scalable strategy. (C) 2021 Elsevier B.V.
