Core–Shell Structured Flame‐Retardant Separator Mediated with Metal–Organic Framework Armor Enables Self‐Acceleration Mechanism for Dendrite‐Free and Safer Lithium Metal Batteries

Developing an optimal multifunctional flame‐retardant separator is crucial for enhancing lithium metal battery (LMB) safety. However, this task poses challenges due to the inferior electrochemical stability and limited ion transport of most fire retardant‐based coatings. In this work, the core–shell...
