The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy. Indeed.
Originally proposed in the 1970s as a possible power source for , and , Li–air batteries recaptured scientific interest late in the first decade of the 2000s due to advances in.
In general lithium ions move between the anode and the cathode across the electrolyte. Under discharge, electrons follow the external circuit to do electric work and the lithium ions migrate to the cathode. During charge the lithium metal plates onto the anode.

If electric cars are to provide the range that drivers demand, they need batteries that can deliver lots more energy, pound for pound, than today''s best lithium-ion batteries can. Lithium-air batteries could—in theory—meet that challenge, but while they are far lighter than their lithium-ion cousins, they are not nearly as efficient.
A counterpart to the non-aqueous Li–air battery is the aqueous Li–air battery (), which utilizes an aqueous electrolyte on the cathode side and an additional lithium-ion conducting separator between the lithium anode and
Previous lithium–air battery projects, typically using liquid electrolytes, made lithium superoxide (LiO 2) or lithium peroxide (Li 2 O 2) at the cathode, which store one or two electrons per

The lithium-air battery holds great promise, due to its outstanding specific capacity of 3842 mAh/g as anode material. The lithium-air battery works by combining lithium ion with oxygen from the air to form lithium oxide at the positive electrode during discharge.
This air purifier uses a rechargeable lithium ion battery that offers a good 10 hours of backup. That means, with a single charge in the morning, you can set off and keep breathing fresh air all day long. A large 400mAh lithium ion battery powers this device up with a very reliable backup time. You can get well over 240 hours (10 to 12 days
