The severe shuttle effect and the sluggish redox reaction kinetics are the two most urgent issues with lithium‐sulfur batteries (LSBs). In this work, Se vacancy‐rich molybdenum selenide‐modified graphene aerogels are designed to serve as both cathode host (MoSe2‐x@GA/S) and freestanding interlayers (MoSe2‐x@GA) for LSBs. The graphene network‐supported binder‐free sulfur host maximizes electron conductivity/Li...
Atomically thin two‐dimensional (2D) materials have emerged as promising candidates for efficient energy harvesting from ionic gradients. However, the exploration of robust 2D atomically thin nanopore membranes, which hold sufficient ionic selectivity and high ion permeability, remains challenging. Here, the single‐layer hexagonal boron nitride (hBN) nanopores are demonstrated as various high‐performance...
