摘要

Fluctuation of oil prices and effects of global warming have forced the scientific-technicalrncommunity to look for the alternative energy storage and conversion systems, such as the smartrngrid. The maximum energy density of current lithium-ion batteries (LIB) is limited because of thernintercalation chemistry of each electrode. Then actual LIBs are not fully satisfactory for thernpractical application of electric vehicles (EV). Therefore metal-air batteries have attracted muchrnattention as a possible alternative, especially for the replacing of the diesel or gasoline, becausernof their energy density is extremely high compared to that of other rechargeable batteries andrntheoretically close to the energy density of the fossil energy (Figure 1) [1]. This technology leadsrnto a very light dispositive where the limited intercalation chemistry is avoided. Li-air batteries arernsuitable for the development of the new generation of EVs. It is estimated that a well optimized Liairrnbattery can yield a specific energy of up to 3000 Wh/Kg, over a factor of 15 greater than thernstate of the art lithium ion batteries [2]. Electrical cars today typically can travel only about 150 kmrnon current LIB technology. The development of the lithium air batteries stands chance of beingrnlight enough to travel 800 km on a single charge and cheap enough to be practical for a typicalrnfamily car. This problem is creating a significant barrier to electric vehicle adoption [3]. However,rnthe impact of this technology has so far fallen short of its potential due to several dauntingrnchallenges which must be overcome as the cyclability or the wide gap between the practical (362rnWh/kg) and the theoretical (11 kWh/g) values of the specific energy [4].
