hi am Rashi Rasak i would like to get details on lithium air battery ppt.My friend Anand said lithium air battery will be available here and i am living at........and i last studied in the college/school .......and now am doing .....i need help on....etc

Lithium–air battery
The lithium-air battery, Li-air for short, is a metal-air battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.[1]
Originally proposed in the 1970s as a possible power source for battery electric vehicles, Li-air batteries recaptured scientific interest in the late 2000s due to advances in materials technology and an increasing demand for renewable energy sources.
Pairing lithium and oxygen (from air) can theoretically lead to electrochemical cells with the highest specific energy possible. Indeed, the theoretical specific energy of a non-aqueous Li-air battery (in the charged state with Li2O2 product and excluding the oxygen mass) is ~12 kWh/kg. This is comparable with the theoretical specific energy of gasoline (~13 kWh/kg). In practice, the Li-air batteries with a specific energy of ~1.7 kWh/kg at the cell level have been developed, which is about 5 times greater than that of commercial lithium-ion batteries, and which is sufficient to run a Fully Electric Vehicle (FEV) for 500 km (311 miles) on a single charge. (A 700 Wh/kg battery with an electric engine would be comparable with the internal combustion engine system in terms of the driving range per kg, while lithium ion batteries have only 105 Wh/kg at the pack level, i.e. they are limited to <150 km (93 miles) driving range). However, the areal power and cycle life of lithium –oxygen/air batteries need significant improvements before they can find any competitive market niche.
Significant advances in multiple fields are necessary to develop a commercial implementation.[2] Four approaches are active: aprotic,[3][4][5] aqueous,[6] solid state[7] and mixed aqueous/aprotic.[8]
Metal-air batteries, specifically zinc-air, have received attention due to potentially high energy densities. The theoretical specific energy densities for metal-air batteries are higher than for ion-based approaches. Lithium-air batteries can theoretically achieve 3840 mA·h/g.
A major driver is the automotive sector. The energy density of gasoline is approximately 13 kW·h/kg, which corresponds to 1.7 kW·h/kg of energy provided to the wheels after losses. Theoretically lithium-air can achieve 12 kW·h/kg (43.2 MJ/kg) excluding the oxygen mass and deliver the same 1.7 kW·h/kg to the wheels, after losses from over-potentials, other cell components and battery pack auxiliaries, given the much higher efficiency of electric motors.
