Abstract Herein, we developed a high‐performance lithium ion conducting hybrid solid electrolyte, consisted of LiTFSI salt, Py 14 TFSI ionic liquid, and TiO 2 nanoparticles. The electrolyte prepared by facile method had high room temperature conductivity, excellent thermal stability low interface resistance with good contact. In addition, the transference number was highly increased scavenger effect With pouch‐type solid‐state battery exhibited initial discharge capacity 150 mA h g −1 at temperature, even 1 C, reversible as 106 .
