The utilization of silicon based anode materials for lithium-ion batteries is hindered by their low intrinsic electronic conductivity, unstable cycling behavior and complex scalable synthesis of nano silicon. Herein, we propose a step-by-step synthesis route to fabricate three-dimensional (3D) graphene nanosheets loaded with Si nanoparticles for lithium ion batteries. For this purpose, silica is deposited...
First-principles calculations are undertaken to analyze the properties of carbon-silicon hybrid materials consisting of silicon modified graphene and defective graphene to evaluate the stability of the structure and their interactions with lithium. Underpotential shifts are determined for the different structures on defective surfaces, showing that decoration of graphene defects with a small number...
