High gravimetric capacity and long cycle life in Mn3O4/graphene platelet/LiCMC composite lithium-ion battery anodes

Abstract We report the synthesis, characterization and battery performance of a novel Mn 3 O 4 /graphene composite based on graphene platelets and also an Mn 3 O 4 /reduced-graphene-oxide composite for comparison. The electrodes were cast from aqueous dispersions in which lithium carboxymethyl cellulose was used as a binder thus enabling an aqueous based process for anode fabrication. The Mn 3 O 4 /graphene-platelet and the Mn 3 O 4 /reduced-graphene-oxide composites anode system possess high gravimetric capacities (∼700 mAh g −1 ) and excellent cycling stability (>100 cycles).
