摘要

Recently, lithium-ion battery has become a hot topic due to its high voltage, high energy density, and long cycle life. Traditional lithium-ion batteries employ graphite as anode materials. However, graphite suffers from several shortcomings, such as low reversible capacity and relatively low cycle life. In this study, graphene was used to replace graphite, and Co3O4 and SnO2 nanoparticles were synthesized on graphene surface. Comparative experiments clearly demonstrate that graphene anchored with Co3O4 or SnO2 nanoparticles synergistically prevented the degradation of graphene anode and the aggregation of Co3O4 and SnO2 nanoparticles during Li+ insertion and extraction process.
