Ion Pathways Optimized via Interlayer Channels in Bimetallic Hydroxides Enable Ultra‐Stable Solid‐State Batteries
Solid polymer electrolytes (SPEs) from electrospinning offer robust mechanical frameworks but often require complex post‐treatments and suffer from low room‐temperature ionic conductivity and sluggish Li + transport, hindering the development of solid‐state batteries. Here, we propose a surface‐grown protective f...
