Abstract Porous architectures are important in determining the performance of lithium–sulfur batteries (LSBs). Among them, multiscale porous architecutures highly desired to tackle limitations single‐sized architectures, and combine advantages different pore scales. Although a few carbonaceous materials with porosity employed LSBs, their nonpolar surface properties cause severe dissolution lithium polysulfides (LiPSs). In this context, structure design noncarbonaceous is required, but has...
We report defect-engineered graphene chemical sensors with ultrahigh sensitivity (33% improvement in NO<sub>2</sub>sensing and 614% NH<sub>3</sub>sensing).
Lithium–sulfur (Li–S) batteries are regarded as potential high-energy storage devices due to their outstanding energy density. However, the low electrical conductivity of sulfur, dissolution active material, and sluggish reaction kinetics cause poor cycle stability rate performance. A variety approaches have been attempted resolve above issues achieve enhanced electrochemical inexpensive multifunctional host materials which can accommodate large quantities sulfur exhibit high electrode...
