英文摘要	A MnO/porous hard carbon (PHC) nanocomposite was prepared by thermolysis of the conjugated microporous polymer incorporated with Mn(CH3COO)(2). The results obtained from scanning electron microscopy, transmission electron microscope and Brunauer-Emmett-Teller analysis show that MnO nanocrystals are uniformly dispersed in the PHC matrix. The rate performance of MnO/PHC electrode at current rates over 5 C is remarkably higher than that of MnO electrode. After 200 charge/discharge cycles, the capacity retention ratio of the MnO/PHC electrode still reaches up to 91.1%. Such a unique performance of the MnO/PHC nanocomposite makes it a promising candidate as an anode material for high performance lithium ion batteries.
