•A lithium-airbatterycomprisesofalithiumnegativeelectrode,apositiveelectrodethatincludesacatalystcontaininggold,andanon-aqueouselectrolyteinterposedbetweenthelithiumnegativeelectrodeandthepositiveelectrode.Inotherwords,itismetal-airbatterychemistrythatusesoxidationoflithiumattheanodeandreductionofoxygenatthecathodetoinduceacurrentflow.Itisanall-solid-statebattery.
•The conceptoflithium-airbatterieswasinitiallyproposedinthe1970sasapossiblepowersourceforbatteryelectricvehicles.Li-airbatteriesrecapturedscientificinterestinthelate2000s,duetoadvancesinmaterialstechnologyandgrowingdemandforrenewableenergysources.

•Metal-airbatteries,specificallyzinc-air,havegarneredattention,duetothepotentialforhighenergydensities.Thetheoreticalspecificenergydensitiesformetal-airbatteriesarehigherthanion-basedapproaches,duetotheuseofatmosphericoxygenasthecathode,removingatraditionalcathodestructure.Recently,lithium-airbatterieshavebeenproposedasthenextstepinlithiumbatteryarchitecture,duetothehighenergydensityoflithium,withrespecttoair(3840mA·h/g).[by Introduction]
