To develop next-generation lithium ion batteries (LIBs) for electric vehicles, it is essential to fulfill the requirements of electrode materials for long cycle stability, high reversible capacity, good safety and fast charge/discharge capability. However, how to controllably synthesize a suitable structure for improved performance according the electrochemical characteristics of active materials remains a challenge. Considering the unique merits of porous carbons such as good physical/chemical stability and controlled structure/morphology, herein, our research work has focused on the designed synthesis for a series of porous carbon-modified metal oxide/sulfide nanohybrids with greatly enhanced electrochemical performance as anode materials for advanced LIBs. Furthermore, we have fundamentally investigated the correlation between the reaction mechanism and their structural features. Our results have established the correlation between the electrochemical performance and their structures, morphologies of electrode materials and electrode architectures, and may help in developing a better understanding of the reaction mechanism of electrode and advantages of carbon materials.
