abstract = {Transition metal oxides are regarded as promising candidates of anode for next-generation lithium-ion batteries (LIBs) due to their ultrahigh theoretical capacity and low cost, but are restricted by their low conductivity and large volume expansion during Li+ intercalation. Herein, we designed and constructed a structurally integrated 3D carbon tube (3D-CT) grid film with Mn3O4 nanoparticles (Mn3O4-NPs) and carbon nanotubes (CNTs) filled in the inner cavity of CTs (denoted as Mn3O4-NPs/CNTs@3D-CT) as high-performance free-standing anode for LIBs. The Mn3O4-NPs/CNTs@3D-CT grid with Mn3O4-NPs filled in the inner cavity of 3D-CT not only afford sufficient space to overcome the damage caused by the volume expansion of Mn3O4-NPs during charge and discharge processes, but also achieves highly efficient channels for the fast transport of both electrons and Li+ during cycling, thus offering outstanding electrochemical performance (865 mAh g−1 at 1 A g−1 after 300 cycles) and excellent rate capability (418 mAh g−1 at 4 A g−1) based on the total mass of electrode. The unique 3D-CT framework structure would open up a new route to the highly stable, high-capacity, and excellent cycle and high-rate performance free-standing electrodes for high-performance Li-ion storage.}
