Abrégé
(EN)
The present invention relates to a lithium-air battery, and more particularly, to a lithium-air battery which comprises a gas diffusion positive electrode formed in a portion thereof contacting air, and which employs a low-volatility electrolyte, thus exhibiting the effect of preventing volatilization of the electrolyte, thereby enabling the battery to be used over a long period of time without safety problems and without degradation of the charging/discharging characteristics of the battery, and the effect of air flowing into the battery being provided in a quicker and more uniform manner while passing through the gas diffusion positive electrode, thus improving the performance of the battery.
