Recently, the research team helmed by Associate Professor Gao Guoxin from the School of Chemistry at Xi'an Jiaotong University has made significant strides in the realm of polymer solid-state electrolytes. They introduced a novel strategy termed "multi-level pore channel nano-aramid-supported dual-crosslinked polymer network." Through the copolymerization of small molecular monomers, they successfully constructed a short ether chain side chain polymer network. By leveraging hydrogen bond self-assembly technology, they further crafted a multi-level pore channel aramid nanofiber aerogel. This innovative method yielded a solid-state electrolyte boasting an ionic conductivity of 10⁻⁴ S/cm at room temperature. Moreover, it facilitated the formation of a "rich organic-rich inorganic bilayer SEI film" at the lithium metal interface, effectively curbing the growth of lithium dendrites. The full cell utilizing this electrolyte demonstrated over 1000 charge-discharge cycles at room temperature, with performance metrics on par with advanced industry standards. The pertinent findings have been published in Advanced Functional Materials.
