Molecularly Woven Artificial Solid Electrolyte Interphase
Abstract
Abstract Lithium‐metal batteries (LMBs) are the most promising candidates for next‐generation high‐energy‐density storage systems, but they suffer from destructive dendrite growth. Here, we integrate cutting‐edge molecular weaving technology into the fabrication of artificial solid electrolyte interphases (ASEI) to realize dendrite‐free and long‐lasting LMBs. Specifically, weaving polymer chains into a 2D plane endows polymer network crystals with high strength and elasticity and creates angstrom‐level meshes for Li‐ion transport and uniform deposition. As a result, related Li plating experiments remained stable at an unprecedentedly high current density of 5 mA cm −2 . Furthermore, full cells with “woven” ASEI exhibited superior long‐term cycling performance compared to existing 2D materials, achieving a capacity retention of 98% over 270 cycles under stringent testing conditions.
