Inferior cycling stability and rate performance respectively caused by rigorous volume change and poor electrical conductivity were the main challenge of state-of-the-art Silicon-based electrode. In this work, silylated functionalized exfoliated graphite oxide (EGO)/[email protected] carbon (3-APTS-EGO/[email protected]) was synthesized by adopting silane as intermediate to connect Si particles with EGO sheets followed by introduction of amorphous carbon. The result suggested that 3-Aminopropyltriethoxysilan connected the EGO sheets and Si nanoparticles via covalent bonds. Owing to the strong covalent interaction and the synergistic effect between the silicon, EGO sheets and amorphous carbon, 3-APTS-EGO/[email protected] composite possessed a high capacity of 774 mAh g⁻¹ even after 450 cycles at 0.4 A g⁻¹ with the retention capacity of 97%. This work also provided an effective strategy to improve the long cycling life performance of Si-based electrode.

严格的体积变化和较差的电导率分别导致较差的循环稳定性和速率性能，这是目前最先进的硅基电极面临的主要挑战。在这项工作中，硅烷化的功能化剥落的氧化石墨（EGO）/ [受电子邮件保护的]碳（3-APTS-EGO / [受电子邮件保护的]）是通过采用硅烷作为中间体，将Si颗粒与EGO片材连接，然后引入无定形碳而合成的。结果表明3-氨丙基三乙氧基硅烷通过共价键连接EGO片和Si纳米颗粒。由于硅，EGO薄片和无定形碳之间的强共价相互作用和协同作用，即使在0.4 A g的电压下经过450次循环，3-APTS-EGO / [受电子邮件保护的]复合材料仍具有774 mAh g ^-1的高容量。^-1，保留容量为97％。这项工作还提供了一种有效的策略，以改善硅基电极的长循环寿命性能。
