A High Power Li-air Battery Enabled by a Fluorocarbon Additive

Abstract

The mass transfer of O2 is a critical factor to determine the rate capability of Li-air battery (LAB). Here, with improved O2 transport enabled by a solution-phase fluorocarbon additive 3-[2-(Perfluorohexyl)ethoxy]-1,2-epoxypropane, the LAB's discharge capacity was significantly elevated to 16368 mAh g-1carbon @500 mA g-1carbon and 1792 mAh g-1carbon @5000 mA g-1carbon under N2-O2 (78:22) with power density comparable with state-of-the-art Li-ion batteries.
