Abstract

A novel hierarchically hollow core?shell MnO2/C superstructure was constructed and evaluated as the anode of LIBs (lithium ion batteries). The loading of MnO2 active material in the hybrid was readily controlled in the range of 50-90 wt%. Such hierarchical architecture provides a unique face-to-face contact mode between carbon. frameworks and hollow MnO2 nanospheres for robust electrical connection as well as well-developed inner voids for MnO2 volume changes and fast ionic transport, simultaneously improving the mechanical stability, utilization, and reaction kinetics of MnO2 anodes. As a consequence, superior cycling performance and excellent rate capability were achieved for MCS@MnO2 as the anode of LIBs.
