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 ...
