▎ 摘　　要

TiO2, SnO2 and Fe2O4 nanoparticles were deposited on the graphene oxide flakes, mixed with C nanotubes and poly(vinylidene fluoride)/hexatluoropropylene copolymer and studied for reversible and irreversible capacity and charging efficiency in Li-ion battery. The Fe and Sn oxide-based composites exhibited the highest initial capacities, whereas the TiO2-based composite showed the best cyclic stability, in spite of a relatively low capacity.
