“…Some of the early work on Li-O 2 batteries was based on carbonate electrolytes including catalysts such as aMnO 2 , Co 3 O 4 , Mn 3 O 4 and PtAu [11][12][13][14][15] . However, carbonate electrolytes were found to decompose in Li-O 2 batteries 1,16,17 and consequently researchers turned to ether-based electrolytes, which have greater stability 8,11,18 . In a dimethoxyethane-based electrolyte, McCloskey et al 19 investigated the electrocatalytic role of Au, Pt and MnO 2 nanoparticles and found that none of these nanoparticles performs better than just a carbon surface.…”

The lithium-oxygen battery, of much interest because of its very high-energy density, presents many challenges, one of which is a high-charge overpotential that results in large inefficiencies. Here we report a cathode architecture based on nanoscale components that results in a dramatic reduction in charge overpotential to B0.2 V. The cathode utilizes atomic layer deposition of palladium nanoparticles on a carbon surface with an alumina coating for passivation of carbon defect sites. The low charge potential is enabled by the combination of palladium nanoparticles attached to the carbon cathode surface, a nanocrystalline form of lithium peroxide with grain boundaries, and the alumina coating preventing electrolyte decomposition on carbon. High-resolution transmission electron microscopy provides evidence for the nanocrystalline form of lithium peroxide. The new cathode material architecture provides the basis for future development of lithium-oxygen cathode materials that can be used to improve the efficiency and to extend cycle life.

“…[ 16 , 17 ] Mizuno et al suggested that this reaction is reversible based on SAED (selected area electron diffraction), EDXS (energy dispersive x-ray spectroscopy), and EELS (electron energy loss spectroscopy) analysis on the discharge products, but the polarization of its decomposition is higher than that of Li 2 O 2 . [ 14 ] This implies that an additional catalyst is required for the oxygen reduction and evolution reactions, since previous catalysts were designed to be effective for the direct formation and decomposition of Li 2 O 2 .…”

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.

“…In fact, most early studies of nonaqueous Li-Air batteries relied heavily on the use of electrolytes based on organic carbonate solvents typically used in Li-ion batteries. However, an early paper by Aurbach and Yeager [15] [16,17], followed by a search for stable nonaqueous electrolytes for Li-O 2 batteries [18].…”

The extremely high theoretical energy density of the lithium-oxygen couple makes it very attractive for nextgeneration battery development. However, there are a number of challenging technical hurdles that must be addressed for LiAir batteries to become a commercial reality. In this article, we demonstrate how the invention of water-stable, solid electrolyte-protected lithium electrodes solves many of these issues and paves the way for the development of aqueous and nonaqueous Li-Air batteries with unprecedented energy densities. We also show data for fully packaged Li-Air cells that achieve more than 800 Wh/kg.
