Graphene-wrapped MnCO3/Mn3O4 nanocomposite as an advanced anode material for lithium-ion batteries:Synergistic effect and electrochemical performances
文献摘要：
Developing new electrode materials with a high specific capacity for excellent lithium-ion storage proper-ties is very desirable.The MnCO3/Mn3O4 nanoparticles with uniform size(about 50 nm)and shape which are wrapped with graphene have been successfully synthesized via the one-step method for anode mate-rial of lithium-ion batteries.The as-prepared graphene-wrapped MnCO3/Mn3O4 nanocomposite exhibits remarkable electrochemical performance,including high reversible specific capacity,outstanding cycling stability,and excellent rate capability in comparison with the bare MnCO3 and MnCO3/Mn3O4 nanocom-posite.This is because the synergistic effect of MnCO3 and Mn3O4 nanoparticles and graphene nanosheets act as both electron conductors and volume buffer layers.From the scanning electron microscopy(SEM)analysis,we confirmed that the morphology and structure of the composite are preserved after 200 cy-cles.This further confirms that graphene-wrapped MnCO3/Mn3O4 nanocomposite acts as a stable tem-plate for reversible lithium-ion intercalation/deintercalation.
