Study of a Li-air battery having an electrolyte solution formed by a mixture of an ether-based aprotic solvent and an ionic liquid

► A new electrolyte for Li-air battery based on an ether aprotic solvent mixed with an ionic liquid. ► Electrolyte was formed by PYR14TFSI ionic liquid added to TEGDME-0.91M LiCF3SO3 solution. ► IL affects the kinetics and the reversibility of the oxygen reactions involved at the cathode.
