A facile synthetic route for Co3O4 nanoparticle/porous carbon composite as an efficient anode material for lithium-ion batteries

摘要

Facile synthesis and electrochemical performance of a Co3O4 nanoparticles/porous carbon composite used as an anode in Li-ion batteries is reported in this work. Co3O4 nanoparticles (5-10 nm in size) were embedded in a disordered porous carbon network using a simple template-free chemical method. The synthesized composite work well as an anode material for Li-ion batteries by delivering stable cycle life and highly reversible capacities of 480 mAhg(-1) at 500mAg(-1), which is higher than that of commercially available graphite electrodes and is comparable to values reported for Co3O4/graphene composites.
