Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

Imaging the Thickness‐Dependent Formation of Schottky Barriers in Metal–Semiconductor van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Using nanobeam photoemission, we demonstrate imaging of the in‐plane and out‐of‐plane electric field landscape within a metal–semiconductor van der Waals heterostructure. We provide evidence for Schottky barrier formation that depends on the semiconductor thickness. ABSTRACT Achieving high‐performance optoelectronic devices based on two‐dimensional van
