چکیده انگلیسی
Flexible and lightweight reduced graphene oxide wrapped Si/carbon fibers paper (Si@RGO/CFP) anodes have been prepared by pyrolysis of the common filter paper, which was soaked into the suspension containing graphene oxide and Si. The reduced graphene oxide wrapped Si nanoparticles (Si@RGO) homogeneously distributed on the interlaced carbon fibers and void among the carbon fibers. The Si@RGO/CFP as a flexible binder-free electrode exhibits an initial reversible capacity of 2055 mAh gâ1 and 1092 mAh gâ1 after 100 cycles for Si@RGO at 100 mA gâ1 along with good rate performance. The superior electrochemical performance of the Si@RGO/CFP is attributed to the interconnected carbon fibers substrate, which provides electronic conduction pathways and works as mechanical support, and the void among carbon fibers accommodates the volume changes of Si and maintains the integrity of the electrode materials.
