Mechanically Interlocked Polymer Electrolyte with Built‐In Fast Molecular Shuttles for All‐Solid‐State Lithium Batteries (Adv. Energy Mater. 44/2021)

All-Solid-State Batteries In article number 2102583, Ji-Hun Seo, Dong-Wan Kim and co-workers design a polyrotaxane based mechanically interlocked polymer that allows the fabrication of materials with high-ionic conductivity, while also having a mechanically tough structure for use in all-solid-state lithium batteries. The advantage of polyrotaxane is that it provides a well-connected pathway for fast/large-charge transport via “built-in molecular shuttles”, which can lead to excellent cycle stability and fast charging performance.
