Multifunctional Separator Coatings for High-Performance Lithium-Sulfur Batteries

A facile and binder-free coating method, termed Langmuir–Blodgett–Scooping, is reported. The method takes advantage of Marangoni stresses and self-assembly to rapidly create functional coating films of various nanomaterials, with single-particle thickness resolution, at an air–water interface (left). Transfer of the film to a conventional separator yields membranes that enhance cathode material utilization in lithium–sulfur batteries (right).
