“…Zhang et al reported that thicker electrodes delivered lower specifi c capacity. [ 34 ] This performance is attributed to slow oxygen diffusion through electrodes immersed in electrolytes. Scanning electron microscopy (SEM) images of the surfaces of the air electrode of a fully discharged cell showed that the voids on the air side were almost fully fi lled by solid deposition; however, the voids on the separator side were still wide open.…”

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.

“…[ 14,15 ] Many researchers are now focusing on the development of advanced catalysts and cathode substrates to improve effi ciency and cycle life using mostly organic electrolytes. Materials used as cathode supports comprise porous carbon, [16][17][18][19] graphene, [ 20 ] carbon nanotubes (CNT) or carbon nanofi bers (CNF) [ 21,22 ] with catalysts such as metal oxides (MnO 2 , [23][24][25][26] Co 3 O 4 , [ 27,28 ] noble metals, [ 7,[29][30][31] and others. [ 32,33 ] At an industrial level, in 2009 IBM launched the "Battery 500" project, which had the ambitious aim of developing a Li/air battery that could ensure a 500 mile driving range, [ 34 ] and it was thought that soon enough this technology would make it to practical applications.…”

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...

“…It can be concluded from the gure with EIS spectra, that the diameter of semi-circles, is increasing due to pulverization of electrodes after each cycle, and this leads to loss of electronic contact between electrolyte and electrodes. In spite of fact that EC/DEC/LiPF 6 electrolyte leads to production of higher electronic contact resistance, analysis after the discharge process has revealed, that the higher resistance is caused by the blocking of the air cathode by Li 2 O 2 , Li 2 CO 3 and nano Al 2 O 3 particles on the air side, after the electrochemical cycling test [6]. The discharge capacity of the nanocomposite EC/DEC/LiPF 6 /5 wt.% Al 2 O 3 yielded lower values, since the nano particles decreased the reaction and led to blocking of GDL cathode air breathing pores and also resulted in increasing contact resistance of the electrodes, because of insulating nature of the nano ceramic powders.…”

Electrolytes based on organic carbonate solvents of ethylene carbonate (EC) and diethyl carbonate (DEC) were prepared by using LiPF6 as the Li-source. Nano sized Al2O3 (50 nm) was used as a reinforcing component in order to control corrosion and Li2CO3 formation. Corrosion of the Li foil anode and electrochemical tests were performed by using EC/DEC/LiPF6 and nanocomposite EC/DEC/LiPF6/5wt.% Al2O3 electrolytes. Electrochemical tests were performed in the swagelok cells by using Li foil anode and carbon air cathode electrodes. Structural tests were carried out by using scanning electron microscopy (SEM), x-ray diraction (XRD) and Raman spectroscopy. Results revealed that incorporation of nano Al2O3 leads to a decrease of corrosion rate of Li anode and a small decrease in the capacity of the air cells.
