Abstract

The mass transfer of O₂ is a critical factor to determine the rate capability of Li-air batteries (LABs). 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 mA h g_carbon^-1@500 mA g_carbon^-1 and 1792 mA h g_carbon^-1@5000 mA g_carbon^-1 in N₂-O₂ (78:22) with power density comparable with state-of-the-art Li-ion batteries.
