Abstract
The utilization of silicon particles as anode materials for lithium-ion batteries is hindered by their low intrinsic electric conductivity and large volume changes during cycling. Here we report a novel Si nanoparticle–carbon nanoparticle/graphene composite, in which the addition of carbon nanoparticles can effectively alleviate the aggregation of Si nanoparticles by separating them from each other, and help graphene sheets build efficient 3D conducting networks for Si nanoparticles. Such Si–C/G composite shows much improved electrochemical properties in terms of specific capacity and cycling performance (ca. 1521 mA h g–1 at 0.2 C after 200 cycles), as well as a favorable high-rate capability.This publication has 37 references indexed in Scilit:
