Abstract

Abstract : Hierarchical MnO2 /C hybrid spheres (MCS@MnO2 ), consisting of numerous hollow core–shell MnO2 @C nanospheres, are developed via a facile deposition process. The well‐defined inner voids and robust carbon framework endow MCS@MnO2 with excellent mechanical stability, efficient utilization of MnO2, and enhanced reaction kinetics for Li‐ion batteries, therefore leading to large specific capacities, superior rate capability, and long‐term cycling stability.
