A rechargeable lithium air battery comprises a non-aqueous electrolyte disposed between a spaced-apart pair of a lithium anode and an air cathode. The electrolyte includes including a lithium salt and an additive containing an alkylene group or a lithium salt and an organosilicon compound. The alkylene additive may be alkylene carbonate, alkylene siloxane, or a combination of alkylene carbonate and alkylene siloxane. The alkylene carbonate may be vinylene carbonate, butylene carbonate, or a combination of vinylene carbonate and butylene carbonate. The alkylene siloxane may be a polymerizable silane such as triacetoxyvinylsilane. In preferred embodiments, the organosilicon compound is a silane containing polyethyleneoxide side chain(s).
