Novel composite polymer electrolyte for lithium air batteries

In the past decade, there have been exciting developments in the fi eld of lithium ion batteries as energy storage devices, resulting in the application of lithium ion batteries in areas ranging from small portable electric devices to large power systems such as hybrid electric vehicles. However, the maximum energy density of current lithium ion batteries having topatactic chemistry is not suffi cient to meet the demands of new markets in such areas as electric vehicles. Therefore, new electrochemical systems with higher energy densities are being sought, and metal-air batteries with conversion chemistry are considered a promising candidate. More recently, promising electrochemical performance has driven much research interest in Li-air and Zn-air batteries. This review provides an overview of the fundamentals and recent progress in the area of Li-air and Zn-air batteries, with the aim of providing a better understanding of the new electrochemical systems.

“…Manganese oxide, in particular, has attracted great interest because of its good ORR activity based on its high specifi c capacity and low cost. [ 8,13,23,25,27,[162][163][164] Bruce and co-workers compared the effectiveness of various crystal structures of manganese oxide and reported α-MnO 2 to have the best catalytic effect for oxygen decomposition and lithium ion coordination. [ 23 ] Moreover, they found the catalytic properties of α-MnO 2 nanowires to be superior to those of spherical MnO 2 , the latter being comparable to that of the porous carbon substrate.…”

gas. At the same time, the penetration of renewable energy sources has opened up the possibility of creating a CO 2 -neutral mobility system, where electric vehicles are powered by wind, hydro, and solar energy.Broad fi nancial efforts are being made at a governmental and industrial level to fund research into new areas of energy storage. The U.S. Department of Energy has allocated $20 million to energy storage research in 2012 and $15 million the following year, while the German government has committed itself to ¤200 million between 2011 and 2018; [ 1 ] similar schemes are also being promoted in Japan by the New Energy and Industrial Technology Development Organization (NEDO). The EU-backed "Horizon 2020" program aims at funding research into energy storage technologies, a fi eld where the European Union lags behind the U.S. and East Asia. [ 2 ] Lithium-ion technology has established itself as a type of reliable energy-storage chemistry over the past 20 years, fi rst being used in camcorders, then mobile phones, laptops, and more recently electric cars. However, as the size of the battery pack increases, so does the belief that the cost per kW h and its energy density are not suitable for practical vehicle applications. The Tesla Model S, which sports a 400 km driving range, does so with a whopping 85 kW h battery pack that alone has up to twice the price of a standard economy car. With a current cost higher than 400 $ kW h −1 , electric cars have so far only entered a niche, high-end market where users are willing to pay a premium. Resizing the battery pack, and so the total cost of an electric car, results in a limited driving range (typically 100-150 km) that automatically restricts the use for long-haul journeys and triggers the so-called "range anxiety" feeling. For these reasons, the need to develop energy-storage technologies that enable at least a 500 km driving range, while retaining the same battery pack volume at an affordable price, is of primary interest for governments and car manufacturers. A Brief History of Lithium/Air BatteriesOver the years, the scientifi c community has focused its interest on advanced lithium-ion and fuel cells with only incremental improvements being made. Lithium-ion technology in particular is predicted to reach an asymptotic limit in specifi c Lithium/air is a fascinating energy storage system. The effective exploitation of air as a battery electrode has been the long-time dream of the battery community. Air is, in principle, a no-cost material characterized by a very high specifi c capacity value. In the particular case of the lithium/air system, energy levels approaching that of gasoline have been postulated. It is then not surprising that, in the course of the last decade, great attention has been devoted to this battery by various top academic and industrial laboratories worldwide. This intense investigation, however, has soon highlighted a series of issues that prevent a rapid development of the Li/air electrochemical system. Although several breakthroughs have be...

:Increasing demand of energy, the depletion of fossil fuel reserves, energy security and the climate change have forced us to look upon alternate energy resources. For today's electric vehicles that run on lithium-ion batteries, one of the biggest downsides is the limited range between recharging. Over the past several years, researchers have been working on lithium-air battery. These batteries could significantly increase the range of electric vehicles due to their high energy density, which could theoretically be equal to the energy density of gasoline. Li-air batteries are potentially viable ultrahigh energy density chemical power sources, which could potentially offer specific energies up to 3000 Whkg −1 being rechargeable. This paper provides a review on Lithium air battery as alternate energy resource for the future.
