Nanomaterials play a key role in improving the next-generation lithium-ion batteries(LIBs) with high power and energy densities[1].Although the electrodes consist of different kind nanomaterials, the properties are strongly depend on their nano-structures and reaction kinetics. Recently, we have focused on the structure design and controlled synthesis of various kinds of manganese oxides as anode materials for high-performance lithium batteries. Base on the fact that large volume expansion and structure collapse of electrodes would happen upon electrochemical cycling[2,3],we develop an effective self-carbonization strategy to fabricate hierarchically porous and carbon compositing manganese oxides. The self-carbonization means that during the calcination, the organic groups in the hierarchical precursors are carbonized into carbon scaffolds along with the crystallization of manganese oxides.
