Lithium-sulfur (Li-S) batteries are considered one of the most promising energy storage systems because of their high energy density and natural abundance of sulfur. However, the inferior cycle stability and low Coulombic efficiency mainly due to the dissolution of ploysulfides impede the practical application of Li-S batteries. Herein, a novel three-dimensional clew-like N-doped multiwalled carbon...
In spite of the ultrahigh theoretical energy density, non-aqueous Li-O2 batteries are still constrained by their inefficient cathodes. Here, we report the synthesis of a distinctive hierarchical carbon architecture (HOM-AMUW) for Li-O2 batteries, which consists of highly ordered macropores (250 nm) with abundant mesopores on their ultrathin walls (4–5 nm). This carbon architecture exhibits unprecedented...
