Construction of sandwiched graphene paper@Fe3O4 nanorod array@graphene for large and fast lithium storage with an extended lifespan

Abstract

Construction of nanostructured building blocks with specific composition, morphology, and internal architectures is an effective and promising strategy to improve the lithium storage of metal oxides. Herein, sandwiched graphene paper@Fe3O4 nanorod array@graphene (GPFG) composites are firstly designed and fabricated as integrated electrodes for high-performance lithium-ion batteries (LIBs). The Fe3O4 nanorod array, directly grown on the conductive graphene paper, assures fast reaction kinetics and high reversibility. The packing graphene not only accelerates the electron transfer but also buffers the volume strain. Therefore, the electrode delivers reasonably large and stable lithium storage, good rate capability, and an amazingly long cycling life of over 1450 cycles.
