In article 1700358, Wei Lv, Quan‐Hong Yang, and co‐workers, develop a dual‐function sulfate templating method to produce a sulfur nanodot cathode with high sulfur loading for lithium‐sulfur batteries towards excellent rate and cycling performance, where sulfate serves as both the sulfur precursor and a template for carbon‐based conducting network formation.
The sulfur content in carbon–sulfur hybrid using the melt‐diffusion method is normally lower than 70 wt%, which greatly decreases the energy density of the cathode in lithium–sulfur (Li‐S) batteries. Here, a scalable method inspired by the commercialized production of Na2S is used to prepare a hierarchical porous carbon–sulfur hybrid (denoted HPC‐S) with high sulfur content (≈85 wt%). The HPC‐S is...
