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

► Graphene/Mn3O4 composites were prepared using LiCMC as the binder. ► Composites are prepared using an aqueous process. ► Commercial graphene platelets and Mn3O4 nanoparticles are used to prepare anodes. ► Composite gives high capacities and long cycle life, comparable to RGO/Mn3O4. ► Thicker graphene platelets can support TMO particles in composite anodes.
