abstract = {As a promising candidate for next generation energy storage devices, lithium sulfur (Li-S) batteries still confront rapid capacity degradation and low rate capability. Herein, we report a well-architected porous nitrogen-doped carbon/MnO coaxial nanotubes (MnO@PNC) as an efficient sulfur host material. The host shows excellent electron conductivity, sufficient ion transport channels and strong adsorption capability for the polysulfides, resulting from the abundant nitrogen-doped sites and pores as well as MnO in the carbon shell of MnO@PNC. The MnO@PNC-S composite electrode with a sulfur content of 75 wt.% deliveries a specific capacity of 802 mAh·g-1 at a high rate of 5.0 C and outstanding cycling stability with a capacity retention of 82% after 520 cycles at 1.0 C.}
