Here,a novel Co3O4/porous graphene nanomesh(PGN) hybrid electrode material is reported.Raman spectraindicates that Co species preferentially anchor on the defective sites of the PGN,which results in markedlyreduced irreversible Li storage and therefore significantly enhanced coulombic efficiency.Besides,the ultrasmallCo3O4 NPs provide a large surface area and a short solid-state diffusion length,which contributesto a high Li-ion capacity at high rate.
