Abstract
Abstract Hybrid solid‐state electrolytes (HSSEs) provide new opportunities and inspiration for the realization of safer, higher energy‐density metal batteries. The innovative application of 3‑dimensional printing in the electrochemical field, especially in solid‐state electrolytes, endows energy storage devices with fascinating characteristics. In this paper, effective dendrite‐inhibited PEO/MOFs HSSEs is innovatively developed through universal room‐temperature 3‑dimensional printing (RT‐3DP) strategy. The prepared HSSEs display enhanced dendrite inhibition due to the porous MOF filler promoting homogeneity of lithium deposition and the formation of C‐OCO 3 Li, ROLi, LiF mesophases, which further improve the migration of Li + in PEO chain and comprehensive performances. This universal strategy realizes the fabrication of different slurry components (PEO with ZIF‐67, MOF‐74, UIO‐66, ZIF‐8 fillers) HSSEs at RT environment, providing new inspirations for the exploration of next‐generation advanced solid‐state batteries.
