A novel small-molecule compound of lithium iodine and 3-hydroxypropionitride as a solid-state electrolyte for lithium–air batteries
A novel small-molecule compound of lithium iodine and 3-hydroxypropionitrile (HPN) has been successfully synthesized. Our combined experimental and theoretical studies indicated that LiIHPN is a Li-ion conductor, which is utterly different from the I–-anion conductor of LiI(HPN) 2 reported previously. Solid-state lithium–air batteries based on LiIHPN as the electrolyte exhibit a reversible discharge capacity of more than 2100 mAh g –1 with a cyclic performance over 10 cycles. Lastly, our findings provide a new way to design solid-state electrolytes toward high-performance lithium–air batteries.
