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