摘 要：The manganese sulfide(MnS) has attracted more attention as anode material on energy storage and conversion field, owing to its high theoretical capacity(616 mA h g-1) and good electrochemical activity. However, low electronic conductivity and large volume expansion during charge-discharge processes have limited its further application. In order to address above mentioned problems, the composites, MnS nanoparticles embedded in N,Scodoped porous carbon skeleton(named as MnS/N,S–C composites), herein have been prepared successfully using metal organic framework(Mn-NTA) as template. The porous carbon skeleton not only can enhance electrode conductivity, but also relieve volume expansion during charge-discharge processes. Thus, the rational design towards electrode architectures has endowed MnS/N,S–C nanocomposites with superior electrochemical performance, which delivers the specific capacities of 676.7 mA h g-1at the current density of 100 mA g-1.
