Abstract	Charging overpotential, which is still relatively too high for non-aqueous electrolyte lithium-air batteries, can be extremely low at high test temperatures. The charging overpotential decreases with the increase of test temperature from 303 K to 343 K. Charging voltage plateau is about 3.1 V and 3.6 V under the current density of 100 mA $g^{-1}$ and 500 mA $g^{-1},$ respectively, at the test temperature of 343 K. X-ray diffraction is carried out to prove the oxidative decompositions of $Li_{2}O_{2}$ during the charging process. The results of electrochemical impedance spectroscopy indicate the influence of test temperature on the charge-transfer resistance. This discovery could lead to new development orientation of lithium-air battery.
